Chemical resistance PP long glass fiber polypropylene pp lgf granules

Product information

PP long fiber reinforced thermoplastic granules is good for the property, like high resistance, high chemical resistance, and so on. It is different about pp resin, pp long glass fiber compound pellets are very useful for car parts, in this time more and more company and factory use long fiber thermoplastic to produce car parts to achieve lightweight of the automobile, The application of long fiber plastic particles will be a new trend in the future development of auto parts.

Product process

PP long glass fiber reinforced thermoplastic suitable for injection molding grade. Like the picture, the long fiber compound injection molding process uses a machine with a single helical structure. The reason is that a single helical structure holds the best performance for long fibers. Does not destroy the fiber tissue, can let the finished product to maintain the best performance. Another double helix in the injection molding process is not suitable for the application of long fibers. When the two screws are machined, the long fibers will break due to extrusion and friction, and the material properties will be greatly reduced.
