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:
Excellent Performance: This material boasts outstanding buffering and seismic performance, allowing it to effectively absorb impact energy. Its resilience makes it a reliable choice for a variety of applications.
Flexible Processing: With its good processing capabilities, it can be molded using various methods like injection molding, extrusion, and blow molding. This versatility enhances its usability across different manufacturing processes.
Chemical Resistance: Resistant to chemical corrosion, it shows a strong resistance to a wide range of substances such as acids, alkalis, and salts. This feature ensures its durability and longevity in harsh environments.
Insulation Properties: Its excellent insulation performance enables it to maintain product temperatures efficiently, making it suitable for applications where temperature control is crucial.
Safety and Environmental Benefits: This material is safe, non-toxic, and environmentally friendly. It does not generate harmful substances during production and use, aligning with sustainable and eco-friendly practices.
