General Introduction of LFT


Long-fiberReinforce Thermoplastic(LFRT), the length of the fiber glass is bigger than 3mm, while the commercialized LFRT is normally 6-25mm.

The modulus of long fiber reinforcement is double than that of short fiber reinforcement, while impact tension is four times, can keep its function without any change under the temperature of minus 30℃

The excellent properties are as following:

  • Non-orientation gridding structure enables it can keep the original property even in high/low temperature and high frequency environment.
  • Excellent anti-impact,high modulus,high strength, low bulkling and similar thermo expansion factor with metal.
  • Low shrinkage,low creep deformation, high dimension stability.
  • High anti-wear and endurance
  • Excellent anti-chemical
  • Excellent surface rating
  • Excellent processing, high flow, easy demould,low damage to screw


We always focusing on new innovation on the LFRT/LFT-D. We have already done such turn-key project for some customers. The projects are LFRT compounding system, LFT-D,LFT-G and LFT-D-ILC.


Our Product Advantages:


1. Professional team working with you together

2. High quality twin screw extruders to make sure the stable extrusion

3. Perfect extrusion die head design to ensure the fiber can immerge into the melt and minimize the fiber floatation.

4. Perfect fiber pre-treatment system

5. Effective fast cooling system for the strands

7. Constant pulling machine

8. Good pelletizer to make sure the uniform granule size

9. Good controlling system for the whole line

10. Turkey projects are available here. One staion service for you.
