What fields are long glass fiber PP used in?
 July 8, 2022
In recent years, long glass fiber modified PP has been extremely popular in the modified plastics industry. Long glass fiber reinforced PP material is cheap and has excellent performance no less than that of reinforced engineering plastics. The combination of these two points shows the advantages of high cost performance and is widely favored by the industry.

At present, these manufacturers have invested a lot of manpower and material resources in the production, research and development and market development of this type of material.
PP material
As one of the general plastic materials, PP has excellent comprehensive properties, good chemical stability, good molding performance and relatively low price; however, fiberglass for PP has low strength, modulus, hardness, poor low temperature impact strength, and molding. The disadvantages of large shrinkage and easy aging.
Generally speaking, the tensile strength of PP material is between 20M~30MPa, the bending strength is between 25M~50MPa, and the bending modulus is between 800M~1500MPa. Therefore, it is modified so that it can be adapted to the needs of the product. Today, each modified PP has a large number of applications in the field of household appliances and vehicles.
long glass fiber

Glass fiber (or fiberglass) is an inorganic non-metallic material with excellent performance. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittleness, resistance Poor abrasiveness. One of the main uses of glass fiber is the reinforcement of composite materials. Long glass fiber generally refers to fiberglass roving with a length of more than 10mm.
