LGF PPS Material for Demanding Environments

Under the circumstances of continuous upgrading in the fields of new energy vehicles, high-end equipment manufacturing and electronic electrical industries, traditional engineering plastics have been unable to meet the comprehensive demands of high temperature, high strength and long-term reliability. LGF PPS (long glass fiber reinforced polyphenylene sulfide) emerged precisely as a high-performance structural composite material solution in response to this trend.

Brief Description of LGF PPS

LGF PPS is made from polyphenylene sulfide (PPS) as the base resin. Through the long glass fiber reinforcement technology, it constructs a stable structural framework system, perfectly integrating the high-temperature resistance, chemical corrosion resistance, electrical insulation and flame retardant properties of PPS with the high strength, high rigidity and anti-fatigue performance of long-fiber reinforced materials.
Compared to traditional short-fiber reinforced PPS, LGF PPS plastic pellet achieves a leapfrog improvement in aspects such as structural strength retention rate, impact resistance, creep and fatigue life, and dimensional stability. It is an ideal choice for metal substitution and lightweight structural design.

Outstanding Performance

Ultra-high heat resistance performance: Continuous operating temperature: 200–220 °C. Short-term heat resistance: high. Maintains stable mechanical properties and dimensional accuracy even in high-temperature environments.

Excellent mechanical strength and structural rigidity: The long glass fiber reinforced structure significantly enhances tensile, bending and impact strength, and provides more reliable long-term creep and fatigue life.

Extremely strong resistance to chemical corrosion: Resistant to acids, alkalis, solvents, and oil. Suitable for chemical, oil and gas, and electronic manufacturing environments.

Exceptional electrical and flame retardant properties: Easy to achieve UL94 V-0 certification, with high volume resistivity and low dielectric loss, suitable for high-voltage systems in new energy vehicles.

Ultra-low water absorption rate and high dimensional stability: The water absorption rate is extremely low, and it maintains precise dimensions and assembly stability even in a humid environment.
