1.PC is the abbreviation of polycarbonate. Polycarbonate in English is Polycarbonate, abbreviated as PC engineering plastic. PC material is actually one of the so-called engineering plastics. As a widely used material worldwide, PC has Its own characteristics, advantages and disadvantages.

PC is an amorphous thermoplastic resin with excellent comprehensive properties. It has excellent electrical insulation, extensibility, dimensional stability and chemical resistance, high strength, heat resistance and cold resistance. It also has self-extinguishing, Flame retardant, non-toxic, colorable and other advantages, you can see the shadow of PC plastic in every corner of your life, large-scale industrial production and easy processing characteristics also make it extremely cheap.

Its strength can meet various needs from mobile phones to bullet-proof glass. The disadvantage is that it has insufficient hardness compared to metal, which leads to its appearance being more easily scratched, but its strength and toughness are very good, whether it is heavy pressure or general beating As long as you are not trying to stone it, it will be long enough.

2. PP is polypropylene resin. Because the homopolymer PP temperature is above 0℃, it is very brittle, so many commercial PP materials are random copolymers with 1 to 4% ethylene or clamps with a higher ratio of ethylene content. Type copolymer.

The copolymer type PP material has a lower heat distortion temperature (100℃), low transparency, low gloss, and low rigidity, but has a stronger impact strength. The strength of PP increases with increasing ethylene content. The Vicat softening temperature of PP is 150℃. Due to the high crystallinity, this material has good surface stiffness and scratch resistance.

"Make good quality luggage" is our commitment to every customer.
