It is widely used in industry and is one of the common polymer
materials.Australian coins are also made of polypropylene. The modified materials are more widely used and can meet more and higher requirements.
PP plastic reinforced with glass fiber
Glass fiber reinforced PP is on the basis of the original pure PP, adding glass fiber and other additives, so as to improve the
scope of use of materials. Generally speaking, most of the glass fiber reinforced materials are used in the structural parts of the product, which is a kind of structural engineering material.
1.The heat resistance temperature of reinforced plastic is much higher than before without glass fiber.
2. The mutual movement between the polymer chains of plastic is limited, therefore, the shrinkage rate of reinforced plastic decreases a lot, and the rigidity is greatly improved.
3.P plastic will not stress cracking, at the same time, the impact resistance of PP improved a lot.
4. After reinforced,which greatly improves the strength of PP, such as tensile strength, compressive strength and bending
5. The combustion performance of PP plastic decreases a lot, flame retardant becomes difficult.
