PC material is actually one of the engineering plastics we call. As a material widely used in the world, PC has its own characteristics and advantages and disadvantages, metal additives or thermoplastic rubber to modify PP. The flow rate of PP has a MFR range of 1~40.8~2, which can be colored. You can see the shadow of PC plastic in every corner of your life. Both homopolymer type and copolymer type PP materials have excellent moisture absorption resistance. PC is an amorphous thermoplastic resin with excellent comprehensive properties, excellent electrical insulation, elongation, dimensional stability and chemical resistance. Sex, higher strength; also has self-extinguishing, heat resistance and cold resistance. Low MFR PP materials have good impact resistance but low elongation, and large-scale industrial production and easy processing characteristics make them extremely inexpensive. Its strength can meet the needs of everything from mobile phones to bulletproof glass. The disadvantage is that it has less hardness and less rigidity than metal. And the uniformity of the shrinkage direction is much better than that of PE-HD, which makes it easier to scratch, but its strength and toughness are very good, whether it is heavy pressure or general beating, as long as you are not trying to use stones. Look at it, it will be long enough.
