LFT-G PPS Polyphenylene sulfide LGF composite long glass fiber customized engineering plastics

What Is PPS?

Polyphenylene Sulfide (PPS) is a high-performance engineering thermoplastic known for its excellent heat resistance, chemical stability, flame retardancy, and mechanical strength. Through reinforcement and modification, PPS offers a well-balanced combination of physical, mechanical, and electrical properties.

PPS features outstanding dimensional stability, corrosion resistance, and electrical insulation performance, making it suitable for harsh industrial environments.

Key Characteristics of PPS

• Excellent high-temperature resistance
• High hardness and wear resistance
• Strong creep resistance under long-term load
• Excellent electrical properties over a wide temperature range
• Low sensitivity of mechanical properties to temperature changes

Unmodified PPS is naturally brittle and has relatively low impact strength. These limitations can be effectively overcome through fiber reinforcement and material modification.

What Is PPS-LGF?

PPS-LGF refers to Polyphenylene Sulfide reinforced with Long Glass Fiber. Among engineering plastics, PPS-LGF stands out for its superior heat resistance, structural strength, and long-term reliability.

• Heat deflection temperature (HDT) above 260°C
• Chemical resistance second only to PTFE
• Low molding shrinkage and extremely low water absorption
• Excellent flame retardancy and vibration fatigue resistance
• Outstanding electrical insulation even in high humidity and high-temperature environments

By incorporating long glass fibers, PPS-LGF significantly improves toughness and impact strength, overcoming the brittleness of pure PPS and delivering excellent comprehensive performance.

In many applications, PPS-LGF can replace metals such as stainless steel, copper, aluminum, and alloys—making it an ideal material for metal replacement and lightweight design.

Applications of PPS-LGF

PPS-LGF is widely used in industries requiring high strength, heat resistance, and chemical stability, including:

• Automotive components
• Aerospace structures
• Household appliances
• Mechanical and structural parts
• Chemical processing equipment
• Electrical insulation and corrosion-resistant components
