Foam material is a porous elastomeric material made by physical or chemical foaming process. In the manufacturing process, the basic polymer (such as polyethylene PE, polyurethane PU, ethylene vinyl acetate copolymer EVA, silicone rubber, etc.) mixed with the appropriate blowing agent to produce many small, uniformly distributed bubbles under specific conditions, resulting in the formation of lightweight materials with a three-dimensional mesh structure. Because it is filled with air, it gives the foam unique physical and mechanical properties, such as low density, high elasticity, sound, and heat insulation, cushioning and shock absorption.
Foam material have the following features: lightweight and elasticity, excellent shielding effectiveness, corrosion resistance, low contact resistance, fast pressure-sensitive fixed, environmental adaptability, Variety of forms and sizes, Good security features.
