People Also Ask:
What is PPS GF40?
It is a high-stiffness, high-strength composite with a PPS matrix and 40% glass fiber. Our long-fiber version enhances this with superior toughness, making it a robust material for structural auto parts and industrial pump parts.
How strong is PPS GF40?
With a tensile strength often exceeding 190 MPa, it is one of the strongest thermoplastics available. Its strength, especially at high temperatures, makes it a viable alternative to metals like aluminum and steel in many applications.
What can replace stainless steel?
For applications requiring high chemical and corrosion resistance, LFT PPS GF40 is an excellent replacement for stainless steel. It offers comparable resistance to a broad range of chemicals at a fraction of the weight and with significantly lower manufacturing costs.

Case Study: Automotive EGR Valve Housing
The Challenge
An automotive Tier-1 supplier needed a material for an Exhaust Gas Recirculation (EGR) valve housing. This component is exposed to one of the harshest environments in a vehicle: continuous high temperatures up to 200°C, and constant exposure to acidic exhaust gases, unburnt fuel, and engine oil. The traditional solution was a costly, heavy, die-cast aluminum part which required significant machining.
The Solution: LFT-PPS-LGF40-NG04
Our PPS long-fiber composite was the only thermoplastic capable of surviving this environment. Its PPS matrix provided complete immunity to the corrosive chemical cocktail, while the 40% long glass fiber reinforcement delivered the high stiffness and creep resistance needed to maintain tight seals and dimensional stability at extreme temperatures. The material's low moisture absorption also ensured consistent performance regardless of humidity.
Result: A 50% lighter EGR housing that passed all thermal shock and chemical exposure tests, enabling a 30% reduction in total part cost and improving overall engine efficiency.
