LFT Polypropylene Manufacturer Glass Fiber filled Compounds high strength lightweight

Due to its advantages of low cost, low density, corrosion resistance, stable processing and chemical properties and recycling, PP has become one of the most widely used general plastics in the world. Its application involves all aspects of production and life.

However, it has a large shrinkage rate, low temperature easy cracking, stiffness and impact performance and other factors, hinder its application in some occasions, so you can use glass fiber to enhance it, so that the cost is reduced, mechanical properties are optimized.

As the industrial development expands its new application range, the development and research of PP modification process has gained attention, prompting it to develop in a new direction. Glass fiber is a very common material in the chemical industry, and its own temperature resistance, flame retardant, corrosion resistance, heat insulation, high tensile strength, good electrical insulation characteristics, often used to manufacture reinforced plastics.

After PP is added, because of the nature of the glass fiber itself, it has the advantages of high tensile strength, good rigidity, non-combustible, good chemical resistance, small size and high cost performance compared with ordinary materials.

PP fiber is a very common kind of glass fiber reinforced material. The high temperature fatigue strength of PP fiber reinforced material is more excellent than that of ordinary PP material. Under the conditions of high temperature and low load for a long time, PP fiber reinforced material will not be deformed, which can make its products have good dimensional stability.

Which Is Better, Homopolymer or Copolymer?

It depends. Neither homopolymer nor copolymer is better than the other.

It will depend on the application as to which is more desirable. Homopolymers are better suited to high-strength and high-hardness applications, whereas copolymers are suited for corrosion resistance and high operating temperatures. Although a raw homopolymer has better mechanical properties, copolymers have better mechanical properties when reinforced with glass over glass-reinforced homopolymer. This is because copolymers are better suited to adhering to fibers.

FAQ

*What processes are LFT materials suitable for?

LFT material is mainly suitable for injection molding, as well as partial extrusion. The requirements for injection molding machines are mainly reflected in the nozzle.

*Why are your products so long? Why does the material I used before, filled with glass fiber, look different than this?

Although long fiber modified materials (LFT) and short fiber modified materials (SFT) are through the combination of fiber and resin to produce higher properties of the complex. However, the two materials are different from the production process, internal structure, appearance, performance, application and so on.

Production process: The fiber of SFT is chopped and mixed with resin, and the production process of LFT is melt impregnation.

Internal structure: The fibers inside SFT particles are short and disordered, while the fibers inside LGF are neatly arranged and longer.

Appearance: The length of SFT is usually less than 3 mm, and the length of LFT is 5-24mm.

Performance: LFT impact performance than SFT increased 1-3 times, tensile strength increased by more than 50%, mechanical properties improved by 50-80%.

Application: LFT is more suitable for use in products with high strength requirements, as load-bearing parts and structural parts.
