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, pvc hose, 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, the solid material into a molten viscous fluid. So the temperature Tm or Tf and Td area between, pvc, defined thermoplastic PVC water pipe processing temperature window. Processing of plastic materials using this feature can be carried out within this temperature window, pvc casing design molded into different shapes PVC pipe or other products. Buy high-quality PVC pipe, make the crown certified quality! ! ! The crown plastic - mainly produces a full range of PU hose (transparent and colored) are consistent with 100% pure TPU polyurethane raw materials higher manufacturing, it does not contain any other material, in line with SGS International Certification; color ingredients (masterbatch) also 100% pure TPU polyurethane raw materials higher carrier; (due to the change of seasons and the choice) hardness of 75A-95A. Professional production processes and machine! Such corporate conscience, it is the only reason to survive in a tough market. pvc pipes _pvc_ the crown plastic pipe products provided by the Dongguan City crown plastic products Limited.
