PVDF vs. PP-FRP for Highly Aggressive Halogens & Hot Acids: Chemical Resistance Engineering
Introduction: Pushing Beyond Polypropylene Boundaries While Polypropylene (PP) handles the majority of industrial acids, certain chemical process conditions—specifically high operating temperatures (>90°C), wet chlorine gas, bromine, concentrated nitric acid, and aggressive organic solvents—rapidly degrade standard polyolefins. For these extreme duty profiles, Polyvinylidene Fluoride (PVDF) dual laminate composites are required. 1. Polymer Structure & Chemical Inertness […]
