In modern society, people’s requirements for product quality are increasing day by day. Under such circumstances, FANG YUAN in Hangzhou boasts a pool of fine teams with rich experience in production and operation. If you are interested in this, you can try to contact them. The team provides EPP machine and EPS machine solutions including design, training, operation and projects.
First of all, EPP polypropylene plastic foam material is a kind of high crystalline polymer material with very good performance, which is environmentally friendly, pressure-resistant, buffering and heat-insulating material. EPP products have excellent shock resistance and energy absorption, high recovery rate after deformation, good heat resistance, chemical resistance, oil resistance and heat insulation. In addition, their light weight can greatly reduce the weight of items.
EPP applications are becoming more and more extensive. IT products, electronic communication equipment, liquid crystal displays, plasma color TVs, precision electronic components, precision instruments and meters have all begun to use EPP as packaging materials. Another particularly important field of application is a large number of applications in the automotive industry: car bumpers, car side shock cores, car door shock cores, advanced safety car seats, child safety seats, tool boxes, trunks, armrests, bottoms Backing plates, sun visors, instrument panels, etc. (According to statistics, the average plastic used in each car is 100~130kg, of which about 4~6kg of EPP plastic is used).
Speaking of EPE, it refers to foamed polyethylene, which is often referred to as pearl cotton. It is a new type of environmentally friendly packaging material. It is composed of a lot of independent bubbles produced by physical foaming of low-density polyethylene resin. It can be extruded or foamed, made into plates, sheets or pipes, and then punched, cut and bonded to form. It has good toughness, is not easy to break, and has good cushioning performance.
The most familiar EPS, polystyrene, is made by pre-expanding, curing, molding, drying and cutting. It can be made into different densities, different shapes of foam products, and can produce various thicknesses of foam boards. Widely used in construction, thermal insulation, packaging, refrigeration, daily necessities, industrial casting and other fields.
Finally, let's talk about EPO, a mixture of expanded polystyrene and polyethylene. It is a "copolymer" produced by a special polymerization process. Its composition and structure are relatively new. It consists of 30% polyethylene and 70% polystyrene. . The PE component is mainly distributed in the outer layer of the particles, which promotes plasticization and bonding between the particles, and the PS component is mainly distributed in the interior of the particles, which has a good supporting effect on the structure of the foam particles.
In the realm of foam block construction, whether it’s used for insulation, roadways, landscaping or commercial buildings, the term “Styrofoam” is often used and misused when referring to expanded polystyrene (EPS) foam blocks. Styrofoam is actually a trademarked word under the Dow Chemical Company that technically refers to closed-cell, extruded polystyrene foam (think foam coffee cups, takeout containers and packing material). However, this extruded polystyrene is often mistakenly used when talking about expanded polystyrene foam which is similar yet different in many ways. If you refer to Styrofoam when you are actually looking for the construction project material known as expanded polystyrene foam blocks, you most definitely will not be getting what you pay for.
As the experts in EPS foam block construction, we’re here to set the record straight about extruded vs expanded polystyrene so you can be better informed as a consumer in the type of materials you invest in for your next project. Here are 5 differences between Styrofoam blocks and EPS foam blocks.
The major difference between Styrofoam and EPS foam blocks is that Styrofoam is made from extruded polystyrene (XPS) while EPS foam blocks are made of expanded polystyrene. So, what’s the actual difference between extruded and expanded? Both are polystyrene foam products made from polystyrene resins but they are manufactured into sheets and blocks very differently. For EPS foam blocks, the blowing agent that is used to form the final product leaves the polystyrene beads quickly which works to create thousands of tiny cells filled with air. The blowing agent used to make XPS or Styrofoam products stays embedded in the beads for long periods of time, thus preventing and reducing air flow through the material. This gives XPS foam a lower moisture absorption rating compared to EPS. To add, XPS is made using a continuous extrusion process that creates a closed-cell form while EPS is manufactured through an expansion process that molds spherical beads and uses heat and pressure to fuse the foam product together.
There are many differences in physical attributes of Styrofoam vs EPS foam blocks. For one, the color is different. You will often see original Styrofoam sheets in a blue color while EPS foam blocks start out as white, unless custom dyed. EPS foam is lightweight but has a high-density which makes it stronger and more durable than Styrofoam. Many will look to EPS as a go-to fill material thanks to its compressive strength and ability to withstand heavy loads over long periods of time. Its permeability rating is higher than Styrofoam, which makes it more optimal for water and mold resistance.
Recyclability is another major differentiating factor between EPS foam and Styrofoam. While Styrofoam is not recyclable, expanded polystyrene is extremely recyclable. It’s considered very green which bodes well with the ever-growing trend toward green construction. The expanded polystyrene is made up of organic elements which means it doesn’t contain toxic chemicals like chlorofluorocarbons (CFCs) or hydrochlorofluorocarbons (HCFCs). Last but not least, the blowing agents used to make EPS are exponentially less harmful to the environment than the ones used to manufacture Styrofoam.
When it comes to using Styrofoam or EPS foam blocks and sheets, EPS is the more ideal option for construction projects that call for durability and resistance against harsh external conditions. Its applications include soil stabilization, road banks, sheathing, below grade applications, insulation, tapered roof insulation, pools and landscaping.
Plastic foam materials are often used in many different daily life applications including packaging, logistics, construction, food and beverage packaging, and stationery applications.
These wide usages of plastic foams also bring the question of whether the foams are recyclable. The short answer is yes, most of the foams such as EPE, EPP, and EPS foams are technically recyclable.
Polymer-based foams are recyclable. The three foam types that are commonly used in production and recycled by foam recycling machines can be categorized as follows.
( EPS foam packaging buffer )
EPS foam (expanded polystyrene foam) is the foam version of polystyrene polymer, which is a white plastic foam primarily used for food and beverage packaging, shipping, stationery applications, etc. EPS foam or expanded polystyrene foam is also commonly known as Styrofoam. Styrofoam, indeed, is a trademarked name for a type of EPS. This foam material consists of rigid and lightweight structures and contains up to 95% of air.
Polyethylene foam, also known as expanded polyethylene (EPE) is a resilient, durable, odorless, and lightweight foam made of PE polymer. The main properties of PE foams can be mentioned as well insulation, vibration protection, and resistance to chemicals and moisture.
( Polyethylene foam rolls )
PE foams are often used for the packaging of fragile goods as well as for heavy goods, electronic products, tools, and machinery. We can also see PE foams in the applications such as floating pool noodles, floor underlays, shock absorbers, sports equipment, and so on.
( PP foam material )

Polypropylene foams, also known as expanded polypropylene (EPP) are famous for their rigid yet flexible structure, flexibility for low and high temperature, and moisture and chemical resistant characteristics. That makes PP foams very convenient to use in applications where durability and lower mass are needed. Therefore, we often see PP foams or EPP in cushioning, heavy-duty packaging, automotive components, thermal, and sound insulation applications.

A roll forming machine is an industrial equipment used to continuously shape sheet metal into specific profiles by passing it through a series of precisely aligned rollers.
The process starts when flat metal coils are loaded into the uncoiler and fed into the machine. As the sheet passes through multiple roll stations, each set of rollers incrementally bends the material until the desired cross-sectional shape is achieved.
This cold forming technique maintains the metal’s thickness while improving its strength and dimensional accuracy. Roll forming is widely used in the production of purlins, metal roofing panels, sandwich panels, garage door panels, and more.
Compared to press brakes or stamping, roll forming offers higher production speed, consistent quality, and cost efficiency for medium to large-scale manufacturing.
More details at our post Unravelling the marvels of Roll Forming Machines.
C and Z purlins are structural steel members used to support roofing and wall cladding in metal building construction. The main difference lies in their shape and application. C purlins have a consistent C-shaped cross-section and are typically used as roof purlins, wall girts, and structural frames where one orientation suffices. Z purlins have a Z-shaped cross-section with an overlapping design that allows them to interlock and be lapped for continuous runs, providing greater structural efficiency over longer spans. Z purlins are commonly chosen when the design requires overlapping sections or when optimizing material for large projects. Our C/Z purlin roll forming machines can produce both profiles with high precision.
More details at our post 7 Key Facts You Must Know about difference between C & Z purlins
Our roll forming machines are designed to process a wide range of materials, depending on your application and product requirements. Common materials include galvanized steel (GI), galvalume steel (GL), cold-rolled steel (CR), hot-dip aluminum-zinc coated steel, pre-painted color-coated steel, stainless steel, and sometimes aluminum sheets.
The machines are capable of handling thicknesses typically ranging from 0.3 mm to 6.0 mm, depending on the profile and material strength. We can also customize the machine design to suit specific materials or surface finishes, ensuring optimal forming performance and minimal surface scratches or deformation.
A PU sandwich panel is a building material consisting of two metal sheets bonded to a rigid polyurethane (PU) foam core.
PU sandwich panels are known for their superior thermal insulation, fire resistance, and long-term durability compared to expanded polystyrene (EPS) panels. PU foam has a much lower thermal conductivity, which means better energy efficiency in buildings.
Additionally, PU panels offer higher compressive strength, better dimensional stability, and reduced water absorption. While EPS panels are cheaper, PU panels provide a more premium solution for cold storage, clean rooms, and energy-efficient buildings.
Our PU sandwich panel production lines deliver high-quality panels with consistent foam density and excellent adhesion.
Our quick-change CZ purlin machines are designed to produce a wide variety of C and Z profiles with different sizes and thicknesses. These machines can switch between C and Z profiles without replacing the rollers manually, thanks to an advanced quick-change mechanism. They are capable of forming purlins with web heights from 80 mm to 300 mm (or more on request) and thicknesses typically between 1.5 mm and 3.0 mm. This flexibility makes them ideal for metal building contractors who need to produce different purlin specifications efficiently. If you have custom profile drawings, we can also adjust the machine settings to accommodate specific dimensions and hole patterns.
Selecting the right roll forming machine depends on several factors. Start by identifying the profile shape and dimensions you need, as this determines the roller design and machine configuration.
Next, consider the material type and thickness, which affect the machine’s forming force and power requirements. Production capacity is another key factor—high-speed lines are recommended for large-scale operations, while simpler manual machines can suffice for smaller jobs.
Also, evaluate the level of automation and budget you prefer. Our engineering team is ready to help you analyze your requirements and recommend the most suitable machine solution to ensure optimal performance and return on investment.
Details at How to choose the right roll forming machine?
Yes, we specialize in manufacturing fully customized roll forming machines, like floor deckin roll forming machine, solar channel roll foring machine, based on your profile drawings and technical specifications. Whether you have standard or non-standard profiles, our engineers will design the roller layout, machine frame, and punching systems to accurately produce your desired shape. We can also integrate additional features such as automatic cutting, punching, embossing, and stacking according to your production needs. Before manufacturing, we’ll provide detailed CAD designs and discuss every detail with you to ensure the final machine meets your expectations.
The main difference lies in the time and effort required to switch between C and Z profiles. In a manual change CZ purlin machine, the operator must manually adjust or replace roller sets to change profiles, which can take up to 30–60 minutes or longer. A quick-change CZ purlin machine, on the other hand, is designed with a mechanical or hydraulic system that allows operators to switch profiles within 3–5 minutes, significantly improving production efficiency. Although quick-change machines have a higher initial cost, they save substantial time and labor in high-volume or multi-profile production environments.
Installing PU sandwich panels properly is crucial for optimal insulation and structural performance. Begin by inspecting the site and ensuring the supporting structure is level and clean.
Use the appropriate fasteners and sealing materials recommended for PU panels. Start installation from one corner and align the first panel accurately to serve as a reference.
Continue placing panels, making sure the joints are tight and sealed to prevent air or water leaks. Avoid damaging the panel surfaces during handling, and follow the manufacturer’s guidelines for cutting and finishing edges.
