EVA Foam


EVA foam is a kind of copolymer, which is foamed from ethylene and vinyl acetate. Generally, the content of EVA is 5% to 40%. Compared with polyethylene, EVA material introduces vinyl acetate monomer in the molecular chain, thereby reducing high crystallinity, improving flexibility, impact resistance, filler compatibility and heat sealing performance.

The classification of EVA foam by EVA manufacturers mainly includes:


1. Color: EVA foam can be divided into four colors: black, white, color and camouflage according to the color;


2. Density: EVA foam can be divided into eight densities of 15 degrees, 20 degrees, 25 degrees, 30 degrees, 38 degrees, 45 degrees, 50 degrees, and 60 degrees according to the density;


3. Processing: According to processing, EVA foam can be divided into six processes: sheet, roll, glue, back glue, molding, and embossing;
