What is EVA foam?
EVA foam material is composed of the main material EVA, fillers, foaming agents, bridging agents, foaming accelerators, lubricants,
and auxiliary materials: leftovers, antistatic agents, flame retardants, quick curing agents, and colorants.
The glue machine beats the raw materials into soft glue, and then presses the soft glue into a sheet through a roller machine.
After putting the sheet material into a large flat foam mold, after a high temperature of 160 to 170 degrees,
the time is generally 90 to 100 seconds. The pressure is 150KG, and the foaming is formed.
This process produces the plate, and the desired size and thickness are drawn through the cutting machine.
Features of EVA and PEVA
| 1. Biodegradable: No harm to the environment when discarded or burned. |
| 2.EVA costs about the same as PVC, more expensive than toxic PVC, but cheaper than PVC without phthalates. |
| 3. Lightweight: The density of EVA is between 0.91-0.93, while the density of PVC is 1.32. |
| 4. Odorless: EVA does not contain ammonian or other organic smells. |
| 5. Heavy metal free: comply with relevant international toy regulations (EN-71 Part 3 and ASTM-F963). |
| 6. Phthalate free: It is suitable for children's toys and does not cause the risk of plasticizer release. |
| 7. High clear, soft and tough: wide application scale. |
| 8. Ultra low temperature resistance (-70C): suitable for icing environment. |
Application range of EVA foam
EVA foam has a certain flexibility, excellent insulation, compressibility and natural surface viscosity, together also play the role of heat preservation, shock absorption and sealing; It can meet the requirements of equipment miniaturization and ultra-thin planning, high technology and availability, wide thickness and use scale. It is an excellent thermal conductivity filling data, widely used in electronic and electrical products. EVA foam has beautiful appearance, shockproof, anti-skid, anti-collision, anti-scratch function, high lightness. Widely used in plexiglass, glass crafts, display shelves, household appliances, furniture products, hardware accessories, plastic products, etc. |
