The Ultimate High-Temp Metal Replacement
When traditional engineering plastics melt and standard die-cast metals corrode, LFT-G® PPS-NA-LGF60 stands resilient. Standard short-fiber PPS GF40 often suffers from brittleness under continuous thermal stress. In stark contrast, our 60% long glass fiber PPS forms an indestructible internal 3D skeletal network. This structural architecture delivers an astonishing 20,000 MPa flexural modulus while locking molecular dimensions in place, ensuring zero warpage even when subjected to continuous 200°C+ extreme heat and aggressive chemical immersion.

Processing Guidelines for High-Temp PPS
Pre-drying
120–140°C / 4–6h
Moisture < 0.02%
Injection
Melt Temp: 300–350°C
Critical Heat Zones
Tooling Settings
Mold Temp: 100–120°C
For Maximum Crystallinity
Engineered for Hostile Thermal & Chemical Environments
Chemical Pump Cases & Impellers
Industrial fluid transfer systems face constant exposure to highly corrosive acids and alkalis. PPS LGF60 offers near-zero water absorption (< 0.02%) and unparalleled chemical inertness, successfully replacing brass and stainless steel impellers while guaranteeing zero dimensional warpage over years of operation.
EV Thermal Management Systems
Electric vehicle cooling modules require plastics that endure continuous coolant immersion and sudden thermal shocks up to 200°C. The robust 3D long glass fiber matrix inside PPS-NA-LGF60 ensures maximum creep resistance under heavy pressure, preventing catastrophic fluid leaks in critical auto systems.
Aerospace Electronic Housings
Electrical housings in aviation demand strict fire safety compliances without using toxic halogen additives. Benefiting from the inherent V-0 flame retardancy of the PPS polymer base, this 60% LGF composite provides a highly rigid, fire-proof, and insulating shield for high-frequency electronics.
