PVC is the growth rate of 4% of the production and application worldwide. PVC growth in Southeast Asia is particularly significant, thanks to the Southeast Asian countries have carried out urgent infrastructure needs. In the three-dimensional surface film can produce the material of the material properties of ABS (acrylonitrile - butadiene - styrene) ABS is used for conveying drinking water, mud and chemicals. The most commonly used DWV (drain waste exhaust) applications. Unplasticized polyvinyl chloride (UPVC) and CPVC (chlorinated polyvinyl chloride after) having the entire operating temperature range within UPVC excellent chemical resistance, with a wide range of operating pressure belt. Due to the nature of long-term high-intensity, stiffness and cost-effectiveness, UPVC systems account for a large proportion of the plastic pipe installation. CPVC is resistant to many acids, bases, salts, paraffins, halogen and alcohols. This is not an anti-solvent, aromatic hydrocarbons and some chlorinated hydrocarbons. PP (polypropylene) Polypropylene is suitable for use in food, drinking water and ultra pure waters, as well as in the pharmaceutical, chemical and other industries. PE (polyethylene) polyethylene has been used successfully for many years pvc pipe drinking water and wastewater, hazardous waste, and safe transportation of compressed gas. Hard PVC pipe has a nominal outside diameter 50CM, but soft PVC pipe is generally the largest of 50mm. pvc pipe fittings rigid PVC pipe specifications: GB / T13020-1991 soft PVC pipe specifications: GB / T13527.1-1992 rigid PVC pipe has a nominal diameter units have :( mm) 2.5,3,4,5,6, .. ... 355,400,450,500,560,630,710,800,900,1000 such as PVC-U and PVC-U difference UPVC and UPVC is what we usually say that the PVC pipe, but the wording of the order just not the same . PVC production process, in order to increase the performance of PVC plastics pvc tubes offer, improve productivity, added plasticizer (such as DOP, DBP pvc pipe technology, DINP, etc.), and add the plasticizer in PVC products will be relatively soft. Generally, we will not add processing plasticizer in PVC products collectively known as UPVC, also writing PVC-U. PVC composition structure qualities yellowish translucent and shiny. Transparency better than polyethylene, polypropylene, polystyrene poor, with the additive of different professional pvc pipe, into soft and hard PVC, soft products soft and tough, feel sticky, hard harder than low-density products polyethylene, polypropylene and lower than at the inflection point will appear bleaching. Common products: plates, pipes, shoes, toys, doors and windows, wire jacket, stationery, packaging boxes.
