Detailed Description
What is CPVC resin? The CPVC resin is made by chlorination modification of PVC resin and is one advanced engineering material. it improve the mechanical performance of numerical heat distortion temperature and chlorine content increases from 56.7% to 63-69% and Vicat softening temperature from 72-82 ℃ to 90-125 ℃ ; its highest service temperature can reach 110 ℃ and long-term service temperature can reach 95 ℃ . Accordingly, CPVC is one kind of advanced engineering plastic with vast foreground. What makes CPVC resin different? 1.chlorinated content:64%-68% 2.Vicat temperature above 125℃ 3.Low thermal conductivity, Low thermal expansion, excellent resistance to non-polar strong acid and alkali Comparison with PVC resin: Index PVC CPVC Density(g/cm3) 1.38—1.45 1.45—1.58 Vicat softening temperature(℃) 72—82 100—125 Tensile strength(MPa) 39—58 54—70 Bend strength(MPa) 105 120 Linear coefficient of thermalexpansion(K-1) (6—7)×10-5 (7.5-8)×10-5 Extension at break 120 50
