LFT Polypropylene PP filling long glass fiber 20%-60% high performance thermoplastic resin

PP material

Polypropylene, PP for short, is a polymer of propylene by adding polymerization. White waxy material, transparent and light in appearance. Polypropylene is a thermoplastic synthetic resin with excellent properties. It is a colorless translucent thermoplastic lightweight general plastic with chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear-resisting machining properties.

PP-LGF material

PP plus glass fiber is by adding glass fiber reinforced PP material, due to the addition of glass fiber, limited the mutual movement between polymer chains of PP plastic, therefore, the shrinkage rate of glass fiber reinforced PP (PP plus glass fiber) decreases, rigidity, impact resistance, tensile strength, compression strength, bending strength and flame retardant are improved.

The mechanical properties of PP plus glass fiber specifically, tensile strength reached 65MPa--90MPa, bending strength reached 70MPa--20MPa, bending modulus reached 3000MPa--4500MPa, such mechanical strength can be completely comparable with ABS and enhanced ABS products, and more heat resistant.

Generally, the heat resistance temperature of ABS and reinforced ABS is between 80℃--98℃, and the heat resistance temperature of glass fiber reinforced PP material can reach 135℃--145℃, and even 150 degrees can withstand more than 1000 hours.

Application of PP-Long glass fiber

PP filling long glass fiber material, can be used to make refrigerators, air conditioning and other refrigeration machines in the axial flow fan and fan. In addition, it can also be used to manufacture the inner drum of high speed washing machine, wave wheel, belt wheel to adapt to its high mechanical performance requirements, used for rice cooker base and handle, electronic microwave oven and other places with high temperature resistance requirements, generally speaking, most glass fiber reinforced PP material is used in the structural parts of the product, is a kind of structural engineering materials.

Frequently asked questions

1. Does long glass fiber injection have special requirements for injection molding machines and molds?

A. There are certainly requirements. Especially from the product design structure, as well as the injection molding machine screw nozzle and mold structure injection molding process must consider the requirements of long fiber.

2. After long glass fiber reinforced, glass fiber can enter the surface of the plastic product during injection molding process, so that the surface of the product become rough and floating fiber. How to make the surface of the material smoothly?

A. During injection molding process need to ensure that the plastic particles are well plasticized and dispersed, also ensure that the drying of plastic particles have no moisture removal, mold temperature adjustment to the appropriate temperature, mold surface is polished in place.

3. Can products with appearance requirements be made of long-fiber materials?

A. The main feature of LFT-G thermoplastic long glass fiber and long carbon is to show the mechanical properties. If the customer has bright or other requirements for the appearance of the product, it needs to be evaluated in combination with specific products,
