Polystyrene Resin for Clear Parts, XPS Board and Thermoforming
General purpose and high impact polystyrene for clear parts, light panels, XPS board and thermoforming.
Polystyrene is chosen for clarity, stiffness and easy processing. BASTONE supplies GPPS from PetroChina Dushanzi and Lianyungang Petrochemical, and HIPS from Dushanzi.
Common Problems in Polystyrene & HIPS
What buyers ask us about, and the grades that solve it.
Clarity that cloudy resin cannot give
Transparent food packaging and light-diffusion parts need high light transmittance and low haze. GPPS 525 and 300NT are specified for those parts.
Recommended grades
Insulation board that needs a steady melt
XPS extrusion needs thermal stability and the right melt flow. GPPS 180NT (1.8 g/10 min) and 500NT target XPS board.
Recommended grades
Brittle parts from rigid polystyrene
HIPS adds impact strength where GPPS would crack. HIE-1 (Charpy 12 kJ/m²) and HIEM serve thermoforming and rigid packaging.

What is GPPS used for?
GPPS serves transparent food packaging, disposable utensils, light diffusion plates, LED light guide plates, XPS insulation board and decorative panels, depending on the grade.
What is the difference between GPPS and HIPS?
GPPS is clear and rigid. HIPS contains rubber that raises impact strength and makes it opaque. Choose GPPS for clarity and HIPS for toughness.
Which GPPS grade suits XPS insulation board?
GPPS 180NT and 500NT are listed for XPS insulation board. 180NT has a melt flow rate of 1.8 g/10 min and high thermal stability.
