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.

The company actively responds to the national call for carbon neutrality, carbon peak green environmental protection and energy saving policy requirements, the use of physical principles for mixing, extrusion, granulation, making the production process more environmentally friendly and energy saving, than the ordinary process (chemical reaction) to reduce the emissions of three wastes, and successfully designed and developed recycled foam recycling operations.
