LFT-G® PP LGF60 Black Structural Long Glass Fiber Polypropylene
LFT-G® PP LGF60 Black (Model: LFT-PP-LGF60-BG06) represents the absolute peak of structural polyolefin performance. By successfully impregnating a highly crystalline polypropylene matrix with 60% continuous long glass fibers through an automated pultrusion manufacturing setup, this engineered composite achieves a staggering flexural modulus exceeding 15,500 MPa. Featuring an optimized black pigment dispersion that improves long-term thermal shielding and UV endurance, it serves as a definitive metal replacement solution for industrial components requiring exceptional mechanical load bearing and strict environmental stability.
Standard short-fiber PP GF60 Black materials frequently suffer from extreme structural brittleness and catastrophic part failure because short chopped fibers act as internal stress faults. Conversely, our premium long glass fiber compound maintains a continuous 10-12mm internal 3D glass matrix. This internal skeleton securely locks the polymer matrix together, minimizing isotropic mold shrinkage, preventing surface wear, and delivering unmatched dimensional stability under severe cyclic fatigue.
Core Material Advantages:
● Extreme Mechanical Rigidity: 15,500 MPa flexural modulus effortlessly replaces die-cast aluminum and zinc alloys.- ● Minimal Isotropic Shrinkage: Ultra-low shrinkage values (0.1-0.2%) prevent part warping and guarantee tight assembly tolerances.
- ● Superior Surface Wear Resistance: The continuous fiber mesh limits subsurface crack propagation and wear abrasion.
- ● Hydrophobic Dimensional Stability: Zero moisture absorption ensures uncompromised mechanical ratings in humid or wet spaces.
