GPPS chemical stands for General Purpose Polystyrene, a widely used plastic material.
What GPPS is
GPPS is a type of Polystyrene, made from the monomer Styrene. It is a transparent, rigid, and brittle thermoplastic.
Key Properties
• Clear and glass-like appearance
• Rigid but brittle (can crack under impact)
• Lightweight
• Good electrical insulation
• Easy to process (injection molding, extrusion)
• Low heat resistance
Common Uses
GPPS is used in everyday products such as:
• Disposable cups and food containers
• CD/DVD cases
• Packaging materials
• Laboratory ware
• Cosmetic containers
GPPS vs HIPS
You may also see HIPS (High Impact Polystyrene):
• GPPS → clear, brittle
• HIPS → opaque, tougher (rubber-modified)
Limitations
• Poor impact resistance
•
