1, PC polycarbonate (Polycarbonate) is a colorless and transparent amorphous thermoplastic material. No. Transparent alloy, mechanical strength is very high, polycarbonate colorless and transparent, heat-resistant, impact-resistant, flame-retardant, do not need additives with UL94V-0 level flame retardant properties. Because of its colorless transparency and excellent impact resistance, common daily applications are CD-ROMs, resin eyeglass lenses, mugs, kitchenware (juicers, etc.), bulletproof glass, goggles, headlights, etc. PC is only hard.
2, PVC (polyvinyl chloride) is currently the second largest production of general-purpose plastics, but also the most widely used plastics, PVC itself is also a colorless and transparent hard materials, but much more brittle than PC, transparency is not as good as PC, other mechanical properties are also very different from PC. But PVC can add a lot of plasticizers, after adding can be made into soft PVC.
The so-called hard PVC is 100 kilograms of PVC resin powder in the amount of plasticizer added less than 5 kilograms of polyvinyl chloride PVC plastic, such as the construction of downpipes, downpipes, plastic windows, credit cards, and so on are belong to the hard PVC. plasticizer added more than 5 kilograms of semi-hard PVC, more than 25 kilograms of soft PVC, such as ordinary downpipe, downpipe, plastic windows, credit cards, and so on, are belong to hard PVC. kg called soft PVC, such as ordinary wire outer skin, disposable infusion tubes, some inflatable toys, soft curtains, supermarkets sell the kind of transparent plastic table mats called soft glass, etc. are soft PVC. PVC can also be any coloring, made of a variety of opaque color products, so PVC is currently the most widely used plastics, the price of only PC 1/2 to 1/4 or so.
PC and PVC material differences
1, PC is polycarbonate plastic, belonging to the category of engineering plastics, good transparency, high strength, good weather resistance, commonly used for optical products, optical discs, sunlight panels, etc.;
2, PVC is polyvinyl chloride plastic, belonging to the category of general-purpose plastics, hard (without plasticizers) PVC products are commonly used for plastic doors and windows, water pipes, threading pipe, sheet, etc., soft (plus plasticizer) PVC products are commonly used in film, soft board, soft sheet, hose, medical products (such as infusion bags, etc.).
3, PC is the three major applications of engineering plastics is the glass assembly industry, automotive industry and electronics, electrical industry, followed by industrial machinery parts, CD-ROMs, packaging, computers and other office equipment, medical and health care, film, leisure and protective equipment, etc. PC can be used as windows and doors, PC laminates are widely used in banks, embassies, detention centers, and public **** places of protective windows for aircraft hatch covers, lighting equipment, industrial safety stalls and bulletproof glass.
4, PVC is one of the world's largest production of plastic products, cheap, widely used, polyvinyl chloride resin is white or light yellow powder. According to different uses can be added to different additives, polyvinyl chloride plastic can show different physical properties and mechanical properties. Adding appropriate amount of plasticizer in PVC resin can make a variety of hard, soft and transparent products. With the booming development of domestic automobile electrical and electronic communication machinery industry, the demand for modified engineering plastics will rise sharply, and a variety of high-strength heat-resistant engineering plastics will be widely used. Polymer alloys, especially nylon alloy, PC alloy will be favored by the market. Green concept will be introduced into the modified engineering plastics industry, a variety of waste recycling will become a common concern in the industry. Reuse, the concept of environmental protection will be integrated into the modified polymer design and manufacturing process.
