pp 40 long glass fiber reinforced polypropylene pellets recycle materials

PP modified material with glass fiber as the reinforcing agent, through a unique process and twin screw combination to control the reasonable length of the glass fiber, the preferred additives make the glass fiber and resin have better compatibility and dispersion, thus greatly improved In addition, the rigidity, impact strength, tensile strength, heat resistance and dimensional shrinkage of the material are different; different customers have different requirements for the product, and the length of the pp lengthened glass fiber can be cut into different lengths of 5-25mm.

In recent years, ordinary polypropylene PP has been filled, reinforced, blended and modified, and then used as raw materials to make industrial supporting parts such as automobiles, electrical appliances, and meters. It has also become its important application field. Copolymer polypropylene or modified polypropylene can be used to make automobile bumpers, dashboards, steering wheels, battery shells, brackets, fenders, cranks, stoppers, fan blades, air-conditioning covers, etc. At present, as far as the world's average level is concerned, the plastic parts used in each car or light vehicle account for about 12% of the total weight of the car, and 20% of them are made of polypropylene PP. In other fields such as washing machines, dishwashers, beverage jugs, tableware as well as instruments, meters, furniture, etc., polypropylene is rapidly increasing in use due to its excellent hygiene, chemical resistance, and high cost performance.
