Molecular formula : MW : CAS :
nature : a non-metallic pipe. Plastic pipe made of the name. The main hardware (qualitative), PVC, use of asbestos Bakelite (France Ouellet), polyethylene, poly-1-butene, modified polypropylene and reinforced plastics (FRP) produced. Light weight, good corrosion resistance and is easily processed, or bending can be arbitrary repression into all sorts of shapes. But the heat and poor heat resistance can not be used to the higher temperature. For example, hard PVC pipe, allowing for -15-60 ° C. Under pressure in general 19.6 MPa (two kilograms of force / cm 2) around. Bakelite asbestos pipe can be used to 130 ° C Hot water pipeline are currently using high heat CPVC or poly-1-butene manufacturers.
