Molding process of EVA foam and anti-static EVA foam
The production principle of EVA foam material is explained as : the foaming agent releases a large amount of gas under the decomposition temperature and pressure and a foam nucleus is formed. After sudden pressure relief, the bubble nucleus causes EVA and other materials to expand to form foam materials. The hardness, density and color can be customized.
EVA foam is a new type of environmentally friendly plastic packaging material. It is easy to be designed, processed and formed. In the field of shockproof packaging, EVA foam has the following advantages:
· It can be cut and shaped;
· Due to the large span of density and hardness, it can be used widely;
· It has the characteristics of non-absorbent and non-toxic, and meets environmental protection requirements;
· It has the advantages of good moisture resistance, heat insulation, buffering, chemical corrosion resistance and earthquake resistance;

Anti-static EVA foam is still based on the principle of EVA foam, and the raw material is involved in anti-static ingredients, so that it has anti-static effect. anti-static EVA is usually black, with the resistance value in the range of 10^6--10^9.
As a new type of environmentally friendly plastic foam material, anti-static EVA foam still has the advantages of good buffering, earthquake resistance, heat insulation, moisture resistance, chemical corrosion resistance and other advantages of ordinary EVA foam, and is non-toxic and non-absorbent.

The benefits of EVA foam production process are self-evident, because EVA foam can be made into different specifications and shapes of products, as long as customers provide corresponding drawings or samples. Shenzhen Yufa Polymer Products Co., Ltd. (Yufa Polymer Products Co.Ltd.) can make satisfactory products for customers.
