Product information

pp plastic

As one of the general plastic materials, PP has excellent comprehensive properties, good chemical stability, better molding performance and relatively low price. But PP has the disadvantages of low strength, modulus, hardness, low temperature impact resistance strength, forming shrinkage, easy aging and so on.

Generally speaking, the tensile strength of PP material is between 20M and 30MPa, the bending strength is between 25M and 50MPa, and the bending modulus is between 800M and 1500MPa. Therefore, it is modified to make it adapt to the demand of the product. Nowadays, each kind of modified PP has a large number of applications in the field of household appliances and vehicles.

Long glass fiber

It is a kind of inorganic non-metallic material with excellent performance. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittle and poor wear resistance. One of the main uses of glass fiber is to reinforce composite materials. Long glass fiber generally refers to the length of more than 10mm glass fiber.

PP-LGF

Long Glass Fiber reinforced PP plastic refers to the modified PP composite material which contains the glass fiber length between 10 and 25mm. After injection molding and other processes, the three-dimensional structure of the glass fiber length is larger than 3.1mm. It is also called Long Glass Fiber polypropylene, or LGFPP.

The material can not only effectively improve the rigidity, impact strength, creep resistance and dimensional stability of the product, but also can make complex products.

Why use LGF instead of SGF

Compared with short fiber reinforced thermoplastic composites, LFT has the following advantages:

• Long fiber length, significantly improve the mechanical properties of products.

• High specific stiffness and strength, good impact resistance, especially suitable for automotive applications.

• Improved creep resistance, good dimensional stability, high component forming accuracy.

• Excellent fatigue resistance.

• Better stability in hot and humid environments.

• The fiber can be relatively moved in the molding mold during the molding process, and the fiber damage is small

Product application

Automotive filed

Front end module, door module, shift mechanism, electronic accelerator pedal, dashboard skeleton, cooling fan and frame, battery carrier, bumper bracket, underbody protection plate, sunroof frame, etc., are used to replace reinforced PA or metal materials. The application of the material in these fields has been widely promoted in Europe, where the current consumption is 20,000 T/Y.

Home Appliance Industry
