What kinds of plastic pipes are available? Which ones are free to deform and turn?! At the same time can bear the pressure of tap water!
PPR give the water pipe, this is the most building, the most commonly used! To meet the high water pressure, adapt to various routes, with a heat capacity and elbow on it!
According to various plastic molding methods, can be divided into film pressure, lamination, injection, extrusion, blow molding, casting plastics and reaction injection plastics and other types.
General purpose thermoplastic plastic, its continuous use temperature below 100 degrees Celsius, polyethylene, polyvinyl chloride, polypropylene, polystyrene and called the four major plastic. Thermoplastic plastics are divided into hydrocarbons, polar genes of vinyl, engineering, cellulose and other types. Become soft when heated, harden when cooled, soften and harden repeatedly, and maintain a definite shape.
There are five kinds of general plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile butadiene styrene copolymer (ABS). These five categories of plastics occupy the vast majority of plastic raw materials used, and the rest can be classified as special plastic varieties, such as: PPS, PPO, PA, PC, POM and so on.
