Product Description
The particle shape of long glass fiber reinforced PP: generally columnar particles with a length of 12 mm or 25 mm and a diameter of about 3 mm. Among them, pellets with a length of about 12mm are mainly used for injection molding, while pellets with a length of about 25mm are mainly used for compression molding.
In this kind of particles, the glass fiber has the same length as the particles, the content of glass fiber can range from 20% to 70%, and the color of the particles can be matched according to customer requirements.
Advantages of LFT compared to short fiber reinforced thermoplastic composites
The longer fiber length significantly improves the mechanical properties of the product.
It has high specific stiffness and specific strength and good impact resistance, and is especially suitable for automotive parts applications.
Improved creep resistance, good dimensional stability, and high component molding accuracy.
Excellent fatigue resistance.
Better stability in high temperature and humid environments.
During the molding process, the fibers can move relative to each other in the mold, and the fiber damage is small.
Long glass fiber reinforced PP manufacturing process
There are three production processes: GMT, LFT-G, LFT-D
Long glass fiber reinforced PP applications
Automotive industry: front-end modules, door modules, shift mechanisms, electronic accelerator pedals, instrument panel frames, cooling fans and frames, battery brackets, bumper brackets, underbody protection panels, sunroof frames, etc., used to replace reinforced PA or metal Material. The application of this material in these fields has been greatly promoted in Europe, and the current consumption is 20,000T/Y.
Home appliance industry: washing machine drum, washing machine tripod bracket, brush machine drum, air conditioning fan, etc., used to replace short glass fiber reinforced PA, ABS or metal materials.
Communications, electronics, and electrical appliance industries: High-precision connectors, igniter components, coil shafts, relay bases, microwave oven transformer coil formers/frames, electrical connectors, solenoid valve packages, scanner components, etc. in the communications electronics industry.
Others: power tool casings, water pump or water meter casings, impellers, bicycle frames, skis, ground motorcycle pedals, civilian safety helmets, safety shoe toe caps, etc., used to replace short glass fiber reinforced PA, PPO, etc.
