Product Description:
EVA Overview
The full name is ethylene vinyl acetate copolymer, also known as EVA.
Raw Material Composition
It is mainly produced by free radical polymerization of two monomers, ethylene and vinyl acetate, with ethylene accounting for more than 80%. During the production process, auxiliary raw materials such as zinc oxide will also be added as stabilizers to improve heat resistance and oxidation resistance; Calcium carbonate, talc powder, and other fillers can reduce costs and improve heat and impact resistance; In addition, there are anti-aging agents, anti ultraviolet agents and other modifiers to improve processing properties and mechanical properties.
Features:
Attribute 1: Has excellent buffering and seismic performance, and can effectively absorb impact energy;
Attribute 2: Good processing performance, can be molded through various methods such as injection molding, extrusion, blow molding, etc;
