Product Description:
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:
Has excellent buffering and seismic performance: This material excels at absorbing impact energy and providing outstanding seismic performance.
Good processing performance: It can be easily molded using different methods like injection molding, extrusion, and blow molding.
Resistant to chemical corrosion: It withstands chemical corrosion and has good resistance to a wide range of chemicals including acids, alkalis, and salts.
Excellent insulation performance: It effectively maintains product temperature and provides reliable insulation.
Safe and environmentally friendly: This material is non-toxic, safe to use, and does not emit harmful substances during production or use.
