Description of eps raw material

Expanded Polystyrene (EPS) is a light polymer. It is a foamed plastic which is added with a foaming agent by using a polystyrene resin and softened at the same time to generate a gas to form a hard closed cell structure. The uniformly closed cavity structure makes the EPS have small water absorption and good heat preservation. , light weight and high mechanical strength Products made from foamed polystyrene are nearly ubiquitous, for example packing materials, insulation, and foam drink cups.
