LFT Material
What is PP LGF40?
LFT-G® PP LGF40 stands at the forefront of polypropylene composites innovation, combining 40% long glass fiber reinforcement with advanced polymer engineering.Designed for manufacturers prioritizing weight reduction without compromising structural integrity, this material delivers exceptional performance-to-cost ratios across automotive, appliances, and industrial sectors.
Why PP LGF40 Outperforms Conventional Options?
While traditional materials face performance compromises, PP LGF40 delivers:
- 55% lower density than aluminum with comparable stiffness
- 3x faster production cycles vs. compression-molded SMC
- Zero corrosion maintenance unlike metals
- Superior fatigue resistance (10⁷ cycles at 50% UTS)

Advantages of LFT long fiber composite
Extremly Mechanical Properties
Keep longer glass carbon fiber,the LFT long fiber composite will provide higher stiffness strength,high modulus, thoughness than short fiber reinforced material
Strong dimensional durability
LFT long fiber composite is made of high-strength fiber materials such as high-flow Polypropylene/Nylon , which greatly improves its durability and strength.
Excellent Chemical Corrosion
LFT Composite choose multi matrix resin from PP to PEEK,Very good corrosion and chemical resistance Retains performance across low and elevated temperatures
Unmatched Impact Resistance
The oriented long glass fiber network in PP LGF40 demonstrates 254% higher impact strength versus short fiber PP composites. This exceptional toughness remains stable at temperatures as low as -30°C, making it ideal for:
- Automotive bumpers
- Outdoor equipment housings
- Cold chain logistics components
PP LGF40 resists degradation from:
- Battery acids (H₂SO₄, HCl)
- Alkaline cleaners (pH 12+)
- Automotive fluids (brake fluid, transmission oil)
- Salt spray (2000+ hours neutral salt spray test)
Emerging applications demonstrate PP LGF40's versatility:
- Drone arm components (5G signal transparent grades)
- Modular construction fasteners (fire-retardant versions)
- Hydrogen fuel cell bipolar plates (conductive variants)
Case Study:
Continental reduced component costs by 18% using PP LGF40 for cable channels while achieving 50% weight savings over metal alternatives.
Next-Gen Appliance Engineering
- Refrigerator structural supports (-30°C cold impact certified)
- Dishwasher sumps (withstands 95°C water/steam cycles)
- Air conditioner fan blades (25% quieter operation)
