Lihat Profil SellerHigh-clarity, heat-resistant GPPS for extrusion applications with low volatility and excellent dimensional stability
GPPS-550P is a premium-grade general purpose polystyrene (GPPS) engineered for extrusion processes. It offers exceptional optical clarity with a subtle blue tint, outstanding thermal resistance, and extremely low volatility (<750 ppm), ensuring cleaner processing and enhanced workplace safety. With balanced mechanical properties—including high tensile and flexural strength, reliable impact resistance, and consistent melt flow—GPPS-550P delivers structural integrity, process reliability, and aesthetic appeal. Ideal for applications requiring transparency, hygiene, and performance under thermal stress, it is widely used in food packaging, consumer goods, lighting components, and rigid sheet products. Manufactured at Vietnam’s only dedicated PS production facility in Vung Tau, every batch undergoes rigorous ASTM-standard testing to guarantee quality and consistency.
