Fluoropolymers for Chemical Industry


Materials for the challenge of chemical industry applications

Materials for the challenge of chemical industry applications

In the chemical industry, fluoropolymers play an indispensable role due to their excellent chemical resistance, mechanical property, thermal property, and weather stability, such as coatings for heat exchangers, pumps, diaphragms, impellers, tanks, reaction vessels, autoclaves, containers, flue duct expansion joints, heavy-wall solid pipe and fittings.

In many cases, fluoropolymers such as PTFE, PFA, FEP and ETFE with inert, non-stick and non-corrosive properties have replaced traditional chlorinated plastics or hydrocarbon plastics, providing higher yields and higher purity process for the chemical and manufacturing industries.
