Do you know these knowledge points about EVA

EVA is a kind of material that we often see in our lives, but many people are not particularly familiar with EVA. What kind of material is EVA foam? What are the uses of EVA? Next, this article will tell you about EVA. Information.

1. What is EVA material?

EVA is a very common material. It has vinyl acetate monomer in its composition, which improves flexibility and impact resistance, compatibility, and heat tight sealing performance. It has good cushioning, shock resistance, heat insulation and moisture resistance. It is extremely resistant to corrosion and is non-toxic and non-absorbent. Most of the slippers sold in the mall are made of eva foam sheets and rubber. It is a relatively common midsole material. It usually has a strong cushioning function and function, but this material is very slippery, so it is usually mixed with hard rubber. Use.

2. What are the usages of EVA?

EVA has strong water resistance, can close the cell structure, and has strong non-absorbent and moisture-proof properties.

EVA is very resistant to corrosion: corrosion, alkali and acid.

EVA's precision processing: no joints, easy to heat compression, split, paste and other processing.

EVA anti-vibration: high shock resistance and cushioning performance.

The EVA resin is an ethylene-vinyl acetate copolymer, and the content of vinyl acetate (VA) is generally 5% to 40%. Compared with polyethylene, EVA is widely used in foaming shoes due to the introduction of vinyl acetate monomer in the molecular chain, which reduces high crystallinity, improves flexibility, impact resistance, filler compatibility and heat sealing performance. Materials, functional shed film, packaging film, hot melt adhesive, wire and cable and toys. In general, the performance of EVA resins depends primarily on the content of vinyl acetate on the molecular chain.

Regarding the materials of EVA and the use of EVA, through the reading of the article, everyone has already had a certain understanding and understanding of this material of EVA. I hope this chapter can help everyone.
