What is PP gf40? 2021-12-22

That is, original polypropylene resin filling 40% glass fiber to improve the performance of polypropylene. Glass fiber modification is one of the most important ways to enhance modification, and glass fiber modification is also divided into short glass fiber modification, long glass fiber modification and continuous fiber modification.

LFT-G company specializes in the production of long glass fiber modified materials, that is, after mixing polypropylene and long glass fiber using a dipping process, the garbage is cut into strips and cut into particles ranging from 5 to 25 mm. The internal fibers of the particles are arranged neatly to strengthen the tensile strength. Strength and mechanical properties. Its performance is between short fiber modification and continuous fiber modification, but the cost performance is higher than these two models.

With the continuous development of science and technology, short fiber modification has become the most common modified material in the composite material industry. Its performance cannot meet the application of many materials, but the long glass fiber modified material can meet its lack of performance. PP LGF is the most advantageous material in terms of comprehensive strength, heat resistance and processing.

Applications:

PP LGF40 applied to lightweight dashboard

The dashboard is an important part of the car interior. In order to improve the perceived quality of the car interior, a soft dashboard is generally used in medium and high-end models, that is, a soft skin layer is added to the surface of the dashboard frame.

As the main part of the instrument panel system, the instrument panel frame is also the load-bearing structure of electrical components and other functional parts. Therefore, it is required to have high strength and high rigidity. At present, the most widely used material on the instrument panel frame is PP with the same density. The PP-LGF material replaces the traditional PP material. While meeting the relevant performance, it can improve the energy absorption performance of the instrument panel. At the same time, the design thickness of the existing instrument panel frame can be reduced from 3mm~3.5mm to 1.8mm~2.5mm, thus Reduce the weight of the instrument panel frame and promote the lightweight of car interiors.
