For industries demanding ultra-high performance composites that balance extreme rigidity, thermal resistance, and structural integrity, LFT-G® PP LGF40 Long Glass Fiber Reinforced Polypropylene sets a new benchmark. Engineered with 40% long glass fibers strategically aligned within the polypropylene matrix, this advanced material outperforms standard LGF30 grades and traditional engineering plastics, delivering unparalleled mechanical properties for mission-critical applications in harsh operating conditions.
Key Features and Benefits
- Superior Load-Bearing Capacity: 40% glass fiber reinforcement boosts tensile strength to 145 MPa (per ASTM D638), enabling use in heavy-load structural components.
- Enhanced Stiffness-to-Weight Ratio: Flexural modulus reaches 6,200 MPa (ISO 178), offering 27% improvement over LGF30 while maintaining lightweight advantages vs. metals.
- Thermal Dimensional Stability: Heat deflection temperature of 162°C (1.8MPa, ISO 75) ensures performance stability in elevated temperature environments.
- Impact Resistance: Notched Charpy impact strength of 45 kJ/m² (ISO 179/1eA) provides exceptional toughness for dynamic load applications.
- Low CTE: Linear thermal expansion coefficient of 0.14×10⁻⁶/K (ISO 11359) minimizes dimensional changes across temperature gradients.
- Chemical Resistance: Maintains PP's inherent resistance to acids, alkalis, and automotive fluids per SAE J2748 standards.
- Eco-Efficient Processing: Compatible with gas-assisted injection molding (GAIM) for complex geometries with 15-20% cycle time reduction.
