Rebounds, PC and PVC, the material is stronger
PVC material is PVC material, is currently general plastics production ranks second, and also the most widely used plastic, PVC itself is a colorless transparent hard materials, but more brittle than PC, transparency is not as good as PC, other mechanical properties is also very different with PC. But PVC can be added a lot of plasticizers, it can be made into soft PVC after adding. The so-called hard PVC is 100 kg PVC resin powder and plasticizer content less than 5 kilograms of PVC plastic PVC, like a sewer pipe, drain pipe, plastic steel windows, credit cards are hard for building PVC. Plasticizer content greater than 5 kg called semi hard PVC, more than 25 kilograms of soft PVC, like ordinary wire skin, disposable infusion tube, inflatable toys, soft curtain, supermarkets that sell soft glass transparent plastic mat are soft PVC. PVC can also be arbitrarily colored, made of a variety of transparent, opaque color products, so PVC is currently the most widely used plastic, the price is only PC of 1/2 to 1/4 or so.
PC material is polycarbonate material, Polycarbonate, is a colorless transparent qualitative thermoplastic material. Mechanical strength is very high, polycarbonate colorless transparent, heat-resistant, shock resistance, flame retardant, without additives, will have UL94, V-0 grade flame retardant performance.
