Lihat Profil SellerHigh-Flow, Crystal-Clear General Purpose Polystyrene for Injection Molding
GPPS Diarex THF77 is a premium-grade general-purpose polystyrene (GPPS) resin engineered for superior processability and optical clarity. Designed specifically for injection molding, this material offers an optimal balance of flow characteristics, mechanical strength, and thermal stability. Its high melt flow rate ensures consistent filling of complex molds with minimal defects, while its excellent transparency makes it ideal for applications where aesthetics and visibility are critical. Compatible with HIPS for enhanced impact resistance, GPPS Diarex THF77 delivers versatility without compromising on performance or safety, meeting the demands of consumer goods, food packaging, and appliance manufacturing.
