PVC heat shrink tubing and pvc insulation casing raw materials are PVC:

PVC (full name polyvinylvinyl chloride), the main ingredient for the polyvinyl chloride, in addition to other ingredients to enhance its heat resistance, toughness, ductility and so on. The top layer of this surface film is a paint, the middle of the main component is polyvinyl chloride, the bottom is the back coating adhesive. It is the world's favorite, quite popular and also widely used in a synthetic material. Its global use in a variety of synthetic materials in the second. According to statistics, only one year in 1995, PVC production in Europe, there are about five million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption of an average of 1.4 million tons. PVC pipe (PVC-U pipe) hard polyvinyl chloride pipe, PVC resin and stabilizer, lubricant, etc. with hot pressing extrusion, is the earliest development and application of plastic pipe. PVC-U pipe corrosion resistance, easy to bond, low price, hard texture, but because of PVC-U monomer and additive exudation, only for the delivery temperature does not exceed 45 ℃ in the water supply system. Plastic pipes are used to transport drinking water, waste water, chemicals, heating fluids and coolants, foodstuffs, ultrapure liquids, muds, gases, compressed air and vacuum systems.
