40% Long Carbon Fiber Reinforced Polyphenylenesulfide (LFT-G® PPS-CF40)
LFT-G® PPS CF40 is a high-performance long-fiber reinforced Polyphenylenesulfide (LCF-PPS) that offers superior high-temperature resistance and exceptional chemical inertness compared to traditional short-fiber PPS CF40. This super engineering plastic, featuring 40% long carbon fiber in an inherently robust PPS matrix, is engineered for the most extreme applications where conventional materials fail. It stands as the ultimate thermoplastic solution for advanced automotive exhaust systems, challenging oil & gas components, and high-performance industrial pump/valve parts. In short, this page details an engineering solution for superior high-temperature performance, ultimate chemical resistance, and excellent structural integrity (LFT-G® PPS CF40-BC04A) - blending the potent mechanical properties of 40% long carbon fiber with the phenomenal thermal stability and chemical inertness of a Polyphenylenesulfide matrix, ideal for next-generation automotive exhaust systems, oil & gas components, and industrial pump/valve parts.
Q: What is carbon fiber PPS used for?
A: It's used in highly corrosive and high-temperature environments, such as automotive exhaust systems, industrial pump components, electrical connectors in harsh conditions, and chemical processing equipment. The inherent chemical resistance of PPS combined with carbon fiber strength is key.
Q: How does PPS CF40 perform at high temperatures?
A: LFT-G® PPS-CF40 exhibits exceptional thermal stability. With a Heat Deflection Temperature (HDT) exceeding 260°C and a continuous use temperature (UL RTI) often above 200°C, it maintains mechanical properties and dimensional stability even under prolonged exposure to extreme heat, making it perfect for automotive and industrial thermal applications.
Q: Can carbon fiber PPS replace metal?
A: Yes, in many applications. LFT-G® PPS-CF40 offers metal-like stiffness and strength while providing significant weight reduction (up to 50%), inherent corrosion resistance, and greater design freedom for complex parts. It's an excellent choice for replacing steel, aluminum, and brass in components exposed to heat and aggressive chemicals, leading to reduced part count and assembly costs, especially for oil & gas operations.

Case Study: Oil & Gas Downhole Pump Impeller
The Challenge
A leading equipment supplier for the oil & gas industry needed a material for impellers in downhole pumps that could operate reliably in extremely corrosive environments (sour gas, brine, hydrocarbons) at high temperatures (up to 200°C) and high pressures. Traditional metal impellers suffered from rapid corrosion and erosion, leading to frequent downtime and high replacement costs. PEEK offered good chemical resistance but was too expensive for large-scale adoption and difficult to process for complex impeller geometries.
The Solution: LFT-G® PPS-CF40
Our LFT-G® PPS-CF40 proved to be the ideal replacement. The inherent chemical inertness of the PPS matrix provided unparalleled resistance to the aggressive downhole fluids, far exceeding that of specialty metals. The 40% long carbon fiber reinforcement delivered exceptional strength and stiffness to withstand high rotational speeds and pressures, preventing creep and deformation. Crucially, the injection molding capability allowed for the production of complex impeller designs with integrated features, achieving significant cost savings compared to machined PEEK or exotic alloys, while dramatically extending service life.
Result: A lighter, corrosion-proof impeller with a 5X longer service life than metal, a 40% reduction in manufacturing cost per part, and improved pump efficiency due to smoother flow geometry.
