Chlorinated polyvinyl chloride
Chlorinated polyvinyl chloride (CPVC), also known as a vinyl chloride, polyvinyl chloride by specific grades (PVC) and under the effect of chlorine substituted in the trigger reaction obtained a new synthetic polymer materials, is a white or slightly yellow powder can flow. Similar to the basic performance and PVC, but the modified PVC resin obtained by chlorination of CPVC, its heat resistance, mechanical properties, chemical stability and flame retardant, etc. to obtain significant improvement is a cheap project plastic.
Chlorinated polyvinyl chloride (CPVC) has excellent heat resistance, chemical resistance, anti-aging properties, flame resistance and high heat distortion temperature, etc., not only has many excellent performance PVC, and good flame resistance and low smoke properties, the ability of most of the acid, alkali, salt, and heat are significantly better than other plastics (PVC can increase than the average 20-40), the Vicat heat resistance is superior to other thermoplastics. As the chlorine content of the product increased, the heat distortion temperature increased significantly, its targets have been increased mechanical strength, its wide range of applications.
Chlorinated polyvinyl chloride can replace traditional thermoplastic engineering plastic, widely used in petroleum, chemical, building materials, shipbuilding, electronics, printing and dyeing, electroplating, food and paper and other fields, mainly for the manufacture of heat resistance, corrosion of pipes and fittings , residential pipe (water pipe) systems, communications pipeline system, sewage piping systems. Meanwhile, according to the different levels of chloride, CPVC chlorinated fiber modification can be used to create composite materials, foam materials, coatings and adhesives. In addition, CPVC also be used as plastic modifiers, blending with the thermoplastic or thermoset plastic blend manufacture of alloys, to improve the material properties, making it superior engineering plastics.
