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
1. 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
2. Warp-Free Dimensional Stability
Unique fiber-matrix bonding technology reduces post-molding shrinkage to 0.15-0.25%, enabling tight-tolerance (±0.1mm) production of:
- Precision gear assemblies
- Electronic connector housings
- Medical device components
