Excellent Properties of Weprofab EVA Sheet
EVA sheet has a low density. It is lightweight and easy to transport. It is very flexible and can be bent and processed into various complex shapes.
EVA sheet has good elasticity, and its closed-cell structure allows it to absorb impact very well, achieving the effect of shock absorption and buffering.
EVA sheet has a wide temperature resistance range and can be used normally in the range of -40°C to 80°C. It also has the characteristics of anti-ultraviolet aging, which is very suitable for outdoor use.
EVA sheet’s closed-cell structure can well prevent water penetration and absorption. Its water absorption rate is less than 1%, which is suitable for humid environments.
EVA sheet is non-toxic, odorless, recyclable, and renewable. After adding flame retardants, it can reach the UL94 V-0 fireproof standard.
The specially treated EVA sheet has a light transmittance of over 90% and a reflectivity of 85-90%, which can significantly improve the power generation efficiency of solar cells.
The resistivity of the EVA sheet can reach 1015 Ω·cm, the dielectric constant is very low, and the insulation performance is very good.
EVA sheet supports hot pressing, screen printing, laser cutting, and other processes, and is easy to bond with other materials.
Intelligent Production Control and Management
Weprofab has high-precision raw material ratio control technology, which can accurately control the proportion of each raw material. And we also have an MES system, which can realize batch tracking from raw material storage to finished product delivery. All data in the production process is uploaded to the cloud in real time, and historical data can be traced back to 3 years ago. Our detection system deploys hyperspectral imaging and machine learning algorithms. It can automatically identify various defects, and the interception rate of defective products is >99.7%, which is 20 times more efficient than manual detection.
Customize Your Own EVA Sheet
Weprofab can customize EVA sheets of different hardness by controlling the content of VA. At the same time, we have engineers with more than 10 years of experience who can specially adjust the material formula for you, and can change the properties of EVA sheets by adding additives such as flame retardants, graphene, silver ion antibacterial agents, etc., to meet your personalized needs. In addition, we can also customize various sizes, thicknesses, and colors, and come with matte, high gloss, texture, and other surface treatments.

How to Produce EVA Sheet?
What steps are required to produce EVA sheet?
Step 1: You need to prepare ethylene, vinyl acetate, and additives such as foaming agent, cross-linking agent, stabilizer, etc., as raw materials, and then use high-speed stirring equipment to evenly mix the raw materials at a temperature of 80-90℃.
Step 2: You need to heat the mixture to 120-160℃ through a twin-screw extruder to melt and plasticize the raw materials. Then use the casting process or calendering process to form the melt into a sheet. This step requires the thickness of the EVA sheet to be precisely controlled through the gap between the rollers.
Step 3: You need to cross-link it at a temperature of 160-200℃ to enhance the mechanical properties of the EVA sheet. At the same time, during this step, the foaming agent will decompose and produce gas, forming a closed-cell foam structure during the cross-linking process.
Step 4: You need to adjust the temperature of the oven to 150-180℃, so that the EVA sheet can complete the final curing in the oven and make the pore structure more stable. Finally, use a water cooling or air cooling system to quickly cool down the EVA sheet and shape it.
Step 5: You need to cut the EVA sheet into sheets or rolls as required, and apply an antistatic layer, UV stabilizer, or perform surface treatments such as matte, high gloss, embossing, etc.
If it is an indentation or dent, you can use a hot air gun to evenly heat the deformed area for 30-90 seconds, and then manually shape the material after it softens, and then shape it after cooling. You can also immerse the damaged EVA sheet in 60-80℃ warm water for 10-15 minutes, take it out and immediately flatten it with a heavy object, and shape it after cooling. If it is a tear repair, you can use EVA special adhesive to apply the cross-section, cover the adhesive surface with release paper, and press and fix it with a clamp for 6-8 hours to repair the crack. If it is a burn mark, you can cut off the carbonized area, embed the gap with an EVA foam filling block of the same density, and use hot pressing welding to achieve seamless repair.
You can use a double-shaft shredder to crush EVA waste into 3-5mm particles, and then use a near-infrared sorting system to identify and separate EVA materials with different VA contents. Then add 5-20% virgin EVA resin and re-melt and regenerate it in a twin-screw extruder. If it is a cross-linked EVA sheet, you can use supercritical CO₂ to destroy the three-dimensional network structure, reduce the gel content from 85% to below 15%, and achieve molecular chain re-plasticization.
The surface of the EVA sheet is easy to accumulate dust and dirt, so you need to clean it regularly. You can use a mild detergent mixed with water, and then gently wipe the EVA sheet with a sponge. Although the EVA sheet is very durable, you should still try to avoid contact with sharp objects and excessive force, which may cause the EVA sheet to break. Although the EVA sheet has good heat resistance, you should still try to avoid leaving it outdoors for a long time.
The price of industrial-grade sheets is about $150-160/cbm, the price of thin sheets is about $1.8-5/sheet, the price of photovoltaic encapsulation special sheets is $2.02/kg, and the price of retail-grade sheets is $7.85/sheet.
Weprofab’s EVA sheet complies with ISO 4597, ASTM D792, UL 94, GB/T 20672, IEC 61215, RoHS 3.0 certifications.
