一.Introduction of LFT
1. LFT（Long-fiber reinforced Thermoplastic）
The length of Long basalt fiber reinforced Thermoplastic is usually above 2 mm, in current processing technology, the length can be remained above 5 mm.
There is a conventional length definition of LFT in auto composites industry—above 10 mm.
2. LFT-G（Long-Fiber Reinforced Thermoplastic Granules）
Long-Fiber Reinforced Thermoplastic Granules were impregnated with molten polymer to basalt fiber bundle in impregnation mould, cutting in a certain length after cover coated and cooling down.
二.LFT pultrusion mold system
The LFT production line of QianYi was introduced from Germany advanced set, which is dedicated to developing and producing high strength, high tenacity, high temperature resistance basalt fiber LFT products.
LFT pultrusion mold production line
This pultrusion mold production line takes advantage of first-class technology and equipment to achieve excellent performance of the products, and we constantly improve the pultrusion solution to meet the customer’s need.
The innovative solutions for lightweight structure
Qianyi company's advanced pultrusion production line of LFT granular materials enables LFT granular materials to have a wide range of optional polymer matrix when reinforced with basalt long fiber.Pultrusion process is the best way to wrap basalt fiber bundles in impregnation mold. The LFT pellets produced are used to produce high strength and low weight plastic parts. The advantages of LFT are widely recognized, especially in automotive components, medical and aerospace components.

四.Performance advantages of basalt long fiber reinforced LFT aggregate
1. Under the condition of high temperature and low load for a long time, it will not produce deformation and has good dimensional stability
2. Fatigue resistance, high temperature resistance, low warpage, aging resistance, less fiber exposure and superior surface properties
3. Small creep property, small anisotropy, low warpage, density < 1.6 g / cm3
4. Good wave transmission and absorption performance, good fluidity, good molding performance, suitable for thin-walled products processing, can be injection molding or extrusion molding
5. It can keep its performance at low temperature and will not be degraded by ultraviolet and electromagnetic radiation
6. Excellent mechanical properties, especially impact resistance, low water absorption, good seawater and salt spray resistance
7. Excellent high temperature creep resistance, high low temperature impact strength, suitable for high and low temperature alternating current applications
