Product Description
Virgin pp pp +glass fiber Melt-blown fabric grade pp
Polypropylene (Polypropylene, referred to as PP) is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents and acid and alkali corrosion. It is widely used in the industry and is one of the common polymer materials. Australian coins are also made of polypropylene.
Why need to modify the virgin PP ?
Usually, PP is modified by adding glass fiber, metal additives or thermoplastic rubber. The MFR of PP mobility ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower tensile strength. For materials with the same MFR, the strength of copolymer type is higher than that of homopolymer type. Due to crystallization, the shrinkage rate of PP is quite high, generally 1.8 to 2.5%. And the directional uniformity of the shrinkage rate is much better than that of materials such as PE-HD. The addition of 30% glass additive can reduce the shrinkage rate to 0.7%.

Injection and pressure preservation:
High injection pressure (1500-1800bar) and holding pressure (about 80% of the injection pressure) are used. About 95% of the total travel time to change the pressure holding, with a longer pressure holding time.
Melting temperature:
The melting point of PP is 160-175 ° C and the decomposition temperature is 350 ° C, but the temperature can not be set above 275 ° C during injection processing. The temperature of the melting section is preferably 240ºC.
