PA6 LGF30 High-Performance Long Glass Fiber Reinforced Nylon 6

30% long glass fiber · injection molding grade · superior mechanical properties & thermal stability

What is PA6 LGF30 Material?

LFT-G® LGF50 PP Composite

LFT-G^® PA6 HLGF30 is a high-performance engineering thermoplastic composed of Nylon 6 (PA6) reinforced with 30% long glass fibers (LGF). Unlike conventional short-fiber compounds, the long-fiber architecture delivers superior load-bearing capacity, impact toughness, and creep resistance, making it the material of choice for lightweight structural components in automotive, industrial, and electrical applications.

The continuous fiber network within each pellet ensures excellent fiber retention after molding, translating into an exceptional strength-to-weight ratio and long-term durability under cyclic loading and elevated temperatures.

FAQ

Q: What is the difference between PA6 LGF30 and PA6 GF30?

A: PA6 LGF30 uses long continuous glass fibers, while PA6 GF30 uses short milled fibers. Compared to short-fiber grades, PA6 LGF30 has 89% higher impact strength, 27% higher flexural modulus, and better heat resistance and creep performance, making it more suitable for load-bearing structural parts.

Q: What is the heat resistance temperature of PA6 LGF30?

A: Per the ISO 75-2 standard, PA6 LGF30 has a heat deflection temperature (HDT) of 208°C at 1.8 MPa. It maintains stable performance for long-term use within -40°C to 120°C, and can withstand short-term peak temperatures up to 180°C.

Q: What drying conditions does PA6 LGF30 need for injection molding?

A: Dry PA6 LGF30 at 80–90°C for 2–4 hours with a dehumidifying dryer before molding. Ensure moisture content is below 0.05% to avoid material degradation and surface defects on finished parts.
