Applications of 1,3-Dichlorohexafluoropropane in Industrial Manufacturing

As a specialized manufacturer, we supply 1,3-dichlorohexafluoropropane primarily for established chemical transformation and high-grade specialty synthesis sectors. Its downstream use falls within stringent regulatory frameworks and demands precise formulation control to meet industrial-scale production needs. Below, we detail authentic application scenarios in which this material serves a critical role throughout the processing chain.

1. Fluoropolymer Intermediate Production

Chemical manufacturers use 1,3-dichlorohexafluoropropane as a precursor in the synthesis of advanced fluoropolymers, such as perfluoroalkoxy (PFA) and fluorinated ethylene propylene (FEP) resins. These resins require feedstock with tightly controlled impurity levels to ensure high molecular weight and consistency in polymerization. The addition occurs during the gas-phase or solution-phase telomerization process, where reactivity and sequence in feed timing affect polymer structure and end-use specifications.
