Description
Product Overview
PPS (Polyphenylene Sulfide) is a high-performance, semi-crystalline thermoplastic with excellent heat resistance, chemical resistance, inherent flame retardancy and good dimensional stability. SZHL supplies high-quality PPS resin pellets suitable for injection molding, extrusion and other processing methods. PPS is widely used in automotive, electrical & electronics, industrial and chemical fields.
Available Specifications
- Standard Grade: General purpose, balanced performance and cost-effectiveness
- Glass Fiber Reinforced: GF 10% / 20% / 30% / 40% – higher strength, higher modulus, improved heat resistance
- Mineral / Carbon Filled: e.g. 10% / 20% / 30% – enhanced stiffness, dimensional stability and wear resistance
- Various grades and custom formulations are available.
