Material Insights – CPVC Explained
CPVC (chlorinated PVC) is a modified version of polyvinyl chloride. Chlorination enhances its molecular irregularity and polarity, improving heat and corrosion resistance.
• Chlorine Content: Increased from 56.7% to 63–69%
• Vicat Softening Point: Improved from 72–82°C to 90–125°C
• Maximum Use Temperature: Up to 110°C (long-term use at 95°C)

Among CPVC variants, CORZAN CPVC is noted for even better performance and durability, making this K-board a versatile choice for crafting robust knife sheaths and outdoor gear accessories.
