Product Description:
EVA, short for ethylene vinyl acetate copolymer, is a polymer material widely used in various industries.
Its raw material composition involves the free radical polymerization of two primary monomers, ethylene and vinyl acetate. Ethylene constitutes more than 80% of its composition, ensuring its essential characteristics. Throughout the production process, additional auxiliary raw materials like zinc oxide are incorporated as stabilizers to enhance its heat and oxidation resistance. Calcium carbonate, talc powder, and other fillers are utilized to lower costs and boost heat and impact resistance. Moreover, anti-aging agents, anti-ultraviolet agents, and other modifiers are included to refine processing properties and mechanical strength.
