Products Introduction

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.
