Sponges are plastic or textiles
The foaming resin, the foaming aid and the binder resin (the finished product having adhesiveness) are mixed together; For foam processing. 80 parts of ethylene vinyl acetate (EVA), 20 parts of APAO PT 3385, 20 parts of azodicarbonamide, 9 parts of CaCO and 0.6 part of dicumyl peroxide were mixed together and placed in a mold, And mechanical resistance to break the hole, you can get foam sponge. The density (d) is 0.028 g / cm, and the compression hardness of 25% is 1.9 KPa.
As well as shock-resistant, anti-friction applications such as elastic materials, such as soles, tractor tanks. Sponge production process is as follows
Sponge: Polyurethane soft foam rubber, polyurethane is the most common in life a polymer material, widely used in the production of various "sponge" products
