CPVC advantage: 1.Using temperature can reach 93-110℃,the highest using temperature can be 110℃,long time used temperature can be 95℃.2.CPVC is a new engineering plastic material made of modified PVC resin.This resin is white or light yellow odorless, tasteless and nontoxic loose granule or powder3.chlorination of PVC resin  irregularity of molecular link , polarity,solubility and chemical stability are addedStandards of CPVC Testing MaterialIndex NameUnitIndexDensitykg/m31450-1650Vicat Softening Temperature℃≧110Vicat Softening Temperature(Fittings)℃≧103 Longitudinal Reversion%≦5Chlorine Concerntration(Mass Percent)%≧60Hydrostatic Test－－No leafing,no breakHydrostatic Reheat Test－－Drop Impact Test－－TIR≦10%Oven TestCal/g/℃No lamination,no crack Modulus of ElasticityMPa≧2660Tensile StrengthMPa≧56 Impact StrengthKJ/m2≧16Coefficient of Linear Expansionm/m℃3.4×10-5Thermal ConductivityCal/g/℃0.14 Specific HeatCal/g/℃0.14Bulk Resistance Ω/cm≧1015Dielectric StrengthAC,KV/mm13Flame Retardant－－Self-extinguish(DIN)CPVC Pipes For Water Supplyoutside diameter dnmean outside diameterpipe seriesS6.3S5S4Dem,minDem,maxnominal wall thickness en 2020.0 20.2 2.0*(1.5)2.0*(1.9)2.3 2525.0 25.2 2.0*(1.9)2.3 2.8 3232.0 32.2 2.4 2.9 3.6 4040.0 40.2 3.0 3.7 4.5 5050.0 50.2 3.7 4.6 5.6 6363.0 63.3 4.7 5.8 7.1 7575.0 75.3 5.6 6.8 8.4 9090.0 90.3 6.7 8.2 10.1 110110.0 110.4 8.1 10.0 12.3 125125.0 125.4 9.2 11.4 14.0 140140.0 140.5 10.3 12.7 15.7 160160.0 160.5 11.8 14.6 17.9 180180.0 180.6 13.3 --200200.0 200.6 14.7 --225225.0 225.7 16.6 --250250.0 250.8 18.4 --280280.0 280.9 20.6 --315315.0 316.0 23.2 --355355.0 356.1 26.1 --400400.0 401.2 29.4 --Note:Considering the request of  stiffness,the minimum wall thickness marked with "*"is  2.0mm.Use the wall thickness in  parenthesis when calculating the hydrostatic test pressure.
