Plastic hose, what is PVC flame retardant HOSE?

Plastic hose, what is PVC flame retardant HOSE? PVC (full name Polyvinylchlorid), the main component is polyvinyl chloride, in addition to other components to enhance its heat resistance, toughness, ductility and so on. The top layer of the surface film is lacquer, the main component in the middle is polyvinyl chloride, and the bottom layer is the back coating adhesive.
PVC pipe (PVC-U pipe) is a rigid PVC pipe, which is extruded by hot pressing after the combination of PVC resin, stabilizer and lubricant. It is the earliest plastic pipe developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price and hard texture. However, because of the leakage of PVC-U monomer and additives, it is only suitable for water supply system with conveying temperature not exceeding 45 C. Plastic pipes are used for drainage, waste water, chemicals, heating and cooling fluids, food, ultra-pure liquids, slurries, gases, compressed air and vacuum systems.
PVC flame retardant hose is a kind of synthetic material which is popular and widely used in the world. Its global usage ranks second in various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the average production and consumption of PVC is one million and four hundred thousand tons.
