What is the difference between foam pad EVA and PE?

Polyvinyl chloride (PVC) has good light transmittance, blocks far infrared rays, strong thermal insulation, soft and easy to shape, good adhesion, good weather resistance and high density. The cost is high, it becomes hard and brittle at low temperature, and it is easy to soften and relax at high temperature. After the additive is precipitated, the film surface is easy to stick to dust, which affects the light transmission. The residual film cannot be burnt, because toxic chlorine gas will be generated. Polyethylene (PE) is light in texture, soft, easy to shape, good in light transmission, non-toxic, has poor weather resistance, poor thermal insulation, and is not easy to bond. Ethylene-vinyl acetate polymer (EVA) has good compatibility and strong tolerance
