Long Fiber Glass Coating LFRT Twin Screw Extrusion Line High Production Capacity
plastic extruder machinery
,lft pellet production line
LFT-D Long Fiber Glass CoatingTwin Screw Extrusion Line for 500kg/hr
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-oriented gridding structure enables it can keep the original property even in high/low temperature and high frequency environment.
- Low shrinkage,low creep deformation, high dimension stability.
- Excellent anti-impact,high modulus,high strength, low bulkling and similar thermo expansion factor with metal.
- Excellent anti-chemical
- Highly anti-wear
- Excellent surface rating
- Excellent processing, highly flow-rate, 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. Perfect fiber pre-treatment system
2. Perfect extrusion die head design to ensure the fiber can immerge into the melt and minimize the fiber floatation.
3.High quality twin screw extruders to make sure the stable extrusion
4. Professional team working with you together
5. Effective fast cooling system for the strands
6.Constant pulling machine
7. Good pelletizer to make sure the uniform granule size
8. Good controlling system for the whole line
9. Turkey projects are available here. One stop service for you.
