Lasenic PVC and CPVC industrial plastic sheets and rods comparison for high temperature and chemical applications

PVC vs. CPVC: Temperature & Chemical Resistance Comparison Guide

Leave a Comment / Uncategorized / By

When specifying thermoplastics for harsh industrial environments, chemical processing systems, or fluid handling equipment, polymer selection often comes down to two dominant materials: Polyvinyl Chloride (PVC) and Chlorinated Polyvinyl Chloride (CPVC). While both materials belong to the vinyl family and share excellent inherent chemical inertness, subtle chemical structural variations result in drastically different thermal limits …
