PP LGF50 Structural Composite | Ultra-High Performance LFT Material | [LFT-G®]

Advanced Composite Engineering
Fiber-Matrix Synergy
- Our 50% long glass fiber reinforced composite achieves unprecedented mechanical performance through:
- Optimized Interfacial Bonding: Maleic anhydride grafted PP enhances fiber-matrix adhesion, achieving interfacial shear strength of 28MPa (ASTM D2344)
- Fiber Length Preservation: Patented pultrusion technology maintains 12mm fiber length with 92% retention rate post-processing
- 3D Orientation Control: ±3° fiber alignment precision through multi-gate injection molding
Manufacturing Excellence
Production process features:
- Precision Temperature Control: 8-zone barrel system (±1.5°C stability) from feed zone (190°C) to die head (230°C)
- Real-time Quality Monitoring: In-line viscosity sensors maintain melt flow rate at 18g/10min (ISO 1133)
- Moisture Management: <0.02% residual moisture through dehumidifying dryers
