PVC pipe fittings using special resin materials
PVC pipe fittings with special resin refers to regular particles in more than 0.90, the main pore properly, the apparent density of 15% higher than the ordinary type, and a good fluidity, easy to melt plasticizing, good mobility, to the satisfaction of the large diameter pipe such as high speed extrusion request, PVC resin production capacity improvement of extruder. Overseas production PVC pipe fittings is widely adopted this kind of resin.
This domestic and resin is still in development and utilization of the start, Tianjin chemical field, South East Su Chlor Alkali Company and Beijing chemical plant has been developed two special resin, although the apparent density is progress, but the existence of VCM residue, the other is still from the processing request gap, especially compared with the overseas finite distance public use resin, otherwise very difficulty. The domestic PVC pipe production plant and research unit, should increase the public PVC pipe resin development efforts, the actual need with pipe processing field, the progress of cooperation itself is also helpful.
