PP LGF50 Composite | High-Strength LFT Polypropylene | LFT-G®
PP LGF50 is a cutting-edge long glass fiber reinforced polypropylene composite engineered for demanding industrial applications. With 50% long glass fiber (LGF) by weight, this material combines the lightweight versatility of polypropylene with exceptional mechanical strength, thermal stability, and fatigue resistance. Designed for metal replacement and structural components, PP LGF50 is ideal for automotive, appliances, and industrial sectors seeking cost-effective, high-performance solutions.
Key Technical Properties
1.Mechanical Performance
- Tensile Strength: 125–150 MPa (ISO 527-2), outperforming short-glass-fiber composites by 20–30%
- Flexural Modulus: 10,000–12,500 MPa, ensuring rigidity for load-bearing parts.
- Impact Resistance: 32–50 kJ/m² at -30°C,retaining toughness even at -30°C
2.Thermal Stability
- Heat Deflection Temperature (HDT): 155–161°C at 1.8 MPa (ISO 75), suitable for under-the-hood
- Low Thermal Expansion: Reduces warping in high-temperature environments.
3.Enhanced Processing
- High Flowability: Enables complex geometries in injection molding
- Low Shrinkage: 0.1–0.3% (ISO 294-4), ensuring dimensional accuracy.
Competitive Advantages
1.Superior Strength-to-Weight Ratio
PP LGF50 achieves 40–50% weight reduction compared to metals like aluminum, reducing energy consumption in transportation...
2.Fatigue and Creep Resistance
The interlaced fiber network dissipates stress, extending product lifespan in cyclical loading applications (e.g., automotive brackets)
3.Chemical and Environmental Resilience
UV Stabilization: Optional additives for outdoor use (e.g., construction equipment).
Low Water Absorption: <0.1%, ideal for washing machine components and humid environments
4.Chemical and Environmental Resilience
Lower Tooling Costs: Simplified injection molding vs. metal stamping.
Part Consolidation: Reduces assembly steps by 30%
Industrial Applications
1.Automotive
- Structural Components: Front-end modules, door panels, and seat frames.
- Under-the-Hood: Engine covers, cooling fans (HDT >150°C)
2.Appliances
- Washing Machine Parts: Drum assemblies, pump housings (low water absorption).
- HVAC Systems: Fan blades, ducting (high rigidity and chemical resistance)
3.Industrial Equipment
- Material Handling: Conveyor belts, robotic arms (wear resistance).
- Renewable Energy: Wind turbine components (fatigue endurance).
