Product Description

PPS + 40% Glass Fiber (GF): High-Performance Thermoplastic for Demanding Industrial Applications
Polyphenylene sulfide (PPS) reinforced with 40% by weight glass fiber - commonly referred to as PPS+40%GF - represents one of the most robust and reliable high-performance thermoplastics available in today's engineered materials portfolio. Engineered for extreme environments where thermal stability, dimensional integrity, chemical resistance, and mechanical strength converge, this composite delivers unmatched performance across aerospace, automotive, electronics, energy, and industrial automation sectors.
At its core, PPS is a semi-crystalline, aromatic polymer renowned for its exceptional inherent flame retardancy (UL94 V-0 without additives), outstanding resistance to hydrolysis and a broad spectrum of aggressive chemicals - including strong acids, bases, solvents, and fuels - even at elevated temperatures. However, unfilled PPS exhibits relatively low stiffness and creep resistance under long-term load. The addition of 40% chopped E-glass fiber dramatically transforms its mechanical profile: tensile strength increases by over 150% (reaching ~200-220 MPa), flexural modulus exceeds 13 GPa, and heat deflection temperature (HDT) under 1.82 MPa rises to approximately 265-290°C - among the highest of all commercially available thermoplastics. Crucially, this reinforcement significantly improves dimensional stability: coefficient of linear thermal expansion (CLTE) drops to ~20-25 × 10E-6/°C (parallel to flow), minimizing warpage and ensuring tight tolerance retention across wide thermal cycles (-60°C to +240°C continuous use).
These synergistic properties make PPS+40%GF uniquely suited for mission-critical structural and functional components where conventional engineering plastics (e.g., PA66, PBT, or even 30% GF PEEK) fall short - either due to insufficient thermal capability, inadequate chemical durability, or excessive cost. In the automotive industry, it is widely specified for under-hood sensor housings, turbocharger components, fuel system connectors, and electric vehicle (EV) battery module frames - benefiting from its non-hygroscopic nature (0.02% water absorption), zero outgassing, and ability to withstand repeated exposure to hot oil, coolant, and battery electrolytes without degradation. In electronics and electrical applications, its intrinsic arc resistance (>175 sec, CTI ≥ 600 V), dielectric stability up to 200°C, and low smoke/toxicity during combustion make it ideal for high-density connector bodies, circuit breaker housings, and 5G base station RF filter brackets operating in harsh outdoor conditions.
Industrial pump components - impellers, valve seats, and seal rings - leverage PPS+40%GF's exceptional wear resistance (especially when paired with compatible counterfaces) and resistance to cavitation erosion in aggressive media such as chlorine-laden water, wastewater, or process chemicals. Similarly, in semiconductor manufacturing equipment, its ultra-low particle generation, cleanroom compatibility (ISO Class 5 compliant when processed properly), and resistance to plasma etchants (e.g., CF4, SF6) enable use in wafer handling arms, chamber liners, and purge ring assemblies.
Importantly, PPS+40%GF maintains excellent processability in standard injection molding equipment - despite its high melt viscosity - enabling complex, thin-walled geometries with high repeatability. It exhibits minimal post-molding shrinkage (<0.2%) and excellent weld line strength, supporting robust, high-yield production of precision parts. While not intended for transparent or aesthetic applications (due to its opaque, dark gray appearance), its functional superiority more than compensates in performance-driven markets.
Backed by ISO 9001-certified manufacturing, rigorous lot-to-lot consistency, and full regulatory compliance (RoHS, REACH, UL recognition), our PPS+40%GF grade is supplied globally in pellet form - ready for direct processing or further compounding with lubricants, PTFE, or carbon fiber for specialized variants. Whether you're designing next-generation EV power electronics, upgrading legacy metal components to lightweight thermoplastics, or solving persistent failure modes in corrosive fluid systems, PPS+40%GF offers a technically sound, economically viable, and future-ready material solution - delivering reliability where it matters most.
