Fiber Reinforcement Technology
- PP LGF50 represents the pinnacle of long glass fiber reinforced polypropylene technology with 50% fiber loading. This aerospace-grade composite delivers exceptional stiffness-to-weight ratios, achieving performance benchmarks previously exclusive to metal alloys. The patented fiber alignment technology ensures optimal load distribution throughout the polymer matrix, enabling isotropic mechanical properties critical for structural applications.
Performance Advantages of 50% Fiber Loading:
- Superior Structural Integrity: 50% LGF reinforcement yields 210% higher flexural strength than standard PP, outperforming many engineering plastics including PA6 and PBT composites
- Enhanced Thermal Performance: Maintains dimensional stability up to 160°C (HDT @1.8MPa), suitable for under-hood automotive applications
- Vibration Damping: 40% better damping coefficient than aluminum alloys, ideal for dynamic load-bearing components
