EVA foam is a new type of environmentally friendly material, a product of foam, and it is also called EVA sponge.
EVA foam can also produce the required colors according to the requirements of customers, including A material, B material, C material, low-odor environmentally friendly materials and non-environmentally friendly materials.
EVA foaming process: at the decomposition temperature of the foaming agent, a large amount of gas is released to form a foam core. After the pressure is suddenly relieved, the release of the foam core causes EVA and other materials to swell and form a foamed material.
EVA foam material grade:
Class C, Class B, Class A, Class 3A, CR material, high elastic EVA material, rubber EVA material, etc. It is often used as the lining of tool boxes and packaging boxes, and is also often used in environmentally friendly toy craft products.
Advantages of EVA foam:
EVA rubber and plastic products are new environmentally friendly plastic packaging materials, which have the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, chemical corrosion resistance, etc., and are non-toxic and non-absorbent. EVA rubber and plastic products are designed to be processed and formed, and their shockproof performance is better than traditional packaging materials such as polystyrene (foam), and they meet environmental protection requirements, making them the best choice for export products. Compared with shock-proof packaging, it can be cut and formed; due to the large difference in density, it can also have a wider range of uses.
Features of EVA foam material:
f. Sound insulation: airtight cell, good sound insulation effect.
Application of EVA foam:
