Polypropylene is a kind of polymer material with low cost, excellent performance and wide range of uses. Through the reinforcement of long carbon fibers, the strength, heat distortion temperature and dimensional stability of polypropylene materials can be improved, and the application field of polypropylene materials can be expanded.
The reinforcement of long fibers and the addition of high crystalline polypropylene resin make the high-temperature fatigue strength of the material at 120 °C twice that of ordinary glass fiber reinforced polypropylene, and even nearly 17% higher than that of glass fiber reinforced nylon, which is famous for its heat resistance. , so this new material has the durability and reliability required as a structural member.
Under the conditions of high temperature and long-term low load, the long carbon fiber reinforced polypropylene PP material will not deform, which can make its products have good dimensional stability. At present, LFT-PP has been widely used in automobiles, power tools, home appliances, and water treatment components. However, each field has different requirements for LFT-PP, please consult us for details.
Advantages of long carbon fiber PP:
The fibers have long length and uniform distribution, and can form a three-dimensional network structure with strong comprehensive mechanical properties.
1. Both bending and tensile strength are increased by 30-100%;
2. The impact resistance is increased by 2-3 times (the impact strength is increased by 2-3 times);
3. Excellent high temperature creep resistance, high low temperature impact strength, suitable for frequent high and low temperature alternating occasions;
4. High dimensional accuracy, small and consistent vertical and horizontal shrinkage;
5. The molding is simple, and it can be injection molded or molded;
6. Low warpage, less glass fiber exposure, good surface performance
