GPO is an engineering grade exploitable polystyrene mixed bead material with adequate impact resistance and toughness. Its main composition is polystyrene, followed by modified materials, and contains 4 ~ 6% of the blowing agent pentane, which is manufactured by extrusion one-step process. Compared with traditional foam materials, GPO can widely replace EPO and EPP in performance and most application scenarios.

On the basis of conventional materials, the company's research and development team jointly initiated the project "Modified flexible polystyrene physical melt load neutral resin halogen-free non-precipitated antistatic material" by well-known universities at home and abroad (Anhui University, South Korea National Busan University), aiming to achieve a breakthrough in the antistatic function of foam packaging materials through physical technology
