Kaneka CPVC is a chlorinated polyvinyl chloride resin developed using Kaneka's unique technology. CPVC is characterized by heat resistance which has been improved by 20 to 40°C without harming PVC's physical and chemical properties. CPVC can be used in applications under high temperatures, where general purpose PVC would soften, rendering it useless.
