LFT-G®PP LGF40: The Ultimate Long Glass Fiber Reinforced Polypropylene Solution
Advanced PP LGF40 Composite Material
What is PP LGF40?
Core Material Science
LFT-G® PP LGF40 is a reinforced thermoplastic that is made up of Copo polypropylene and 40%long glass fibers.LFT-G® PP LGF40 represents a breakthrough in polymer composites, combining:
- High-crystallinity polypropylene matrix (≥95% isotactic index)
- 40wt% E-glass fibers with 12mm nominal length
- Proprietary interfacial coupling agents
The manufacturing process utilizes state-of-the-art pultrusion technology with:
- Precise fiber alignment control (±3° orientation)
- Multi-stage melt impregnation system
- Closed-loop viscosity monitoring
Performance Advantages
PP LGF40 delivers exceptional mechanical properties through:
- Fiber length preservation >90% after processing
- Three-dimensional reinforcement network
- 0.02-0.04mm fiber diameter optimization
Key benefits for engineers:
- 45% higher specific strength vs aluminum alloys
- Vibration damping coefficient of 0.15-0.25
- -40°C to +135°C operational range
