High Performance PPS Engineering Plastics Long Glass Fiber Plastic Compounds

What Is PPS GF?

Our PPS (Polyphenylene Sulfide) composite reinforced with continuous long glass fibers (LGF) delivers exceptional mechanical strength, outstanding chemical and thermal resistance, and superior dimensional stability. Engineered for demanding industrial applications where high performance, reliability, and long-term durability are critical.

Technology Behind the Strength
Continuous Long Glass Fiber Reinforcement
Unlike short fiber composites, our PPS-LGF materials contain long glass fibers (typically 12–25 mm) that are carefully oriented and embedded during compounding and molding. This continuous fiber architecture creates a robust internal skeleton, significantly enhancing tensile strength, flexural modulus, impact toughness, and fatigue resistance.

Advanced Compounding & Pultrusion Process
Using state-of-the-art pultrusion and compounding technologies, the long glass fibers are uniformly dispersed and protected within the PPS matrix. This ensures excellent fiber-matrix adhesion, consistent fiber length retention, and stable mechanical performance with minimal fiber breakage.

Exceptional Chemical and Thermal Resistance
PPS polymer backbone provides excellent resistance to harsh chemicals such as acids, bases, fuels, oils, and solvents. It also withstands continuous operating temperatures up to ~260°C (500°F), making it ideal for high-temperature environments where other thermoplastics degrade.

Dimensional and Creep Stability
The combination of PPS’s inherent thermal stability and long glass fiber reinforcement results in minimal thermal expansion and outstanding creep resistance, essential for precision components in aerospace, automotive, and electronics.

Where It Works Best
Designed for the most challenging environments where standard plastics fail to meet the performance requirements:

Automotive:
High-temperature engine components, fuel system parts, electrical connectors, and brackets requiring excellent chemical resistance and mechanical stability.

Electrical & Electronics:
Insulating housings, circuit breakers, connectors, and components exposed to elevated temperatures, chemicals, and mechanical stresses.

Industrial Equipment:
Chemical-resistant pumps, valves, compressor parts, structural supports, and components in harsh chemical processing environments.

Energy & Aerospace:
Battery housings, fuel cell components, and lightweight structural parts demanding long-term thermal and chemical durability.

Consumer Goods:
High-performance parts in appliances and tools that require durability, heat resistance, and dimensional stability under mechanical load.
