Product Overview
Kingfa PPS-G40 BK111 is a modified Polyphenylene Sulfide (PPS) material designed for applications requiring high thermal stability, strong mechanical properties, and excellent dimensional accuracy.
With a heat deflection temperature above 250°C, UL 94 V-0 flame retardancy, and very low molding shrinkage, it is widely used in automotive, electrical, and industrial components that operate under extreme heat and mechanical stress.
Key Features
• Heat deflection temperature above 250°C for high-temperature environments
• Excellent dimensional stability with low shrinkage (0.2–0.4%)
• High tensile and flexural strength for structural applications
• UL 94 V-0 flame-retardant rating for safety-critical components
• High volume resistivity suitable for electrical insulation
• Reliable performance in harsh chemical and thermal conditions
• Optimized for precision injection molding
Typical Applications
• Automotive under-the-hood parts (connectors, housings, sensors)
• Electrical sockets, insulators, and enclosures
• Industrial pumps, seals, and high-temperature valve components
• High-temperature appliance components
• Aerospace and precision mechanical engineering parts
