What is PA6 LGF30 Material?
LFT-G® PPS LGF50 is an advanced high-performance engineering thermoplastic composed of Polyphenylene Sulfide (PPS) reinforced with 50% long glass fibers (LGF). Designed for extreme operating environments, this long fiber reinforced PPS compound provides outstanding heat resistance, dimensional stability, and chemical durability compared with conventional short-fiber PPS grades.
The unique long glass fiber structure creates a stable reinforcement network throughout molded parts, enabling excellent creep resistance, low moisture sensitivity, and reliable mechanical performance under continuous high temperatures and aggressive chemical exposure. PPS LGF50 is widely used for precision structural components, electrical systems, and industrial applications requiring long-term reliability.
