Dongguan to the crown Plastic Products Co., said PVC water pipe can be combined in various ways to produce the raw material of different properties to PVC pipes. Now some type of PVC water pipe hot melt performance. Hot melt PVC pipe can be further processed, hot melt plastic tube important temperature parameters glass transition temperature Tg, viscous flow temperature Tf, the crystal melting temperature Tm and the thermal decomposition temperature Td. Crystalline PVC plastic at or above the crystal melting temperature Tm crystalline plastic viscous flow at temperatures above the temperature Tf, pu, the solid material into a molten viscous fluid. Therefore, Tf and Tm or Td temperature region between the definition of thermoplastic PVC water pipe processing temperature window. Processing of plastic materials using this feature can be in this temperature window, the design is formed into various shapes PVC pipe or other products.
