The granulates in long-fiber plastics are approximately 10 mm long, which is also the length of the fiber. Long fibers are used in most engineering plastics, usually with PP and PA.
Why choose?
- Significantly improved impact resistance; retains in sub-zero temperatures.
- Excellent creep resistance
Why not choose?
- If you want improvement in modulus only, the positive effect of long fibers is rather small.
- Changing from normal length fibers to long fibers has its complications due to the runner system requirements.
Typical applications:
- Car parts
