产品说明：
    氯化聚氯乙烯（CPVC）又名过氯乙烯，是由特定牌号的聚氯乙烯（PVC）与氯气在引发作用下进行取代反应而制得的一种新型合成高分子材料，是一种白色或微黄色可流动固体粉末。基本性能与PVC相仿，但PVC树脂经氯化改性后制得的CPVC，其耐热性能、物理机械性能、化学稳定性能及阻燃性等获得显著改善，是一种质优价廉的工程塑料。
    氯化聚氯乙烯（CPVC）具有良好的耐热性、耐化学腐蚀性、防老化性能、阻燃性和热变形温度较高等优点，既具有PVC的很多优良性能，又有良好的阻燃性和低发烟特性，能耐大多数的酸、碱、盐，而且耐热方面明显优于其它塑料（比普通PVC能提高20－40℃），其维卡耐热温度优于其它热塑性塑料。该产品随着氯含量的提高，其热变形温度明显上升，其机械强度指标也相应提高，其应用范围十分广泛。
    氯化聚氯乙烯可取代传统的热塑性工程塑料，广泛应用于石油、化工、建材、造船、电器、印染、电镀、食品及造纸等领域，主要用于制造耐热、耐腐蚀的管道和配件、住宅管（热水管道）系统、通信管道系统、排污管道系统等。同时，根据氯化程度的不同，CPVC还可用于氯化纤维的改性、制造复合材料、发泡材料、涂料及粘合剂等。另外，CPVC还可用作塑料的改性剂，与热塑性或热固性塑料掺合共混制造合金，改善材料的性能，使之成为更优越的工程塑料。             
 
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.
