Foam
Foam is a kind of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, shock absorption, etc., and its dielectric performance is better than that of matrix resin, so it has a wide range of uses. Common foam materials include polyurethane (PU) foam, polystyrene (PS) foam, polyolefin foam, polyvinyl chloride (PVC) foam, phenolic foam, epoxy resin foam, etc.
