Polychlorotrifluoroethylene_(PCTFE)

polymer

Polychlorotrifluoroethylene (PCTFE) is a thermoplastic fluoropolymer that combines chlorine and fluorine atoms in its backbone, offering a unique balance of chemical resistance and mechanical rigidity compared to other fluoropolymers. It is widely used in aerospace, pharmaceutical, and chemical processing industries where exposure to aggressive solvents, fuels, and corrosive environments demands both durability and dimensional stability. PCTFE is particularly valued in applications requiring lower creep and superior chemical resistance to oils and chlorinated solvents compared to PTFE, making it the preferred choice for precision-critical seals, tubing, and valve components in harsh operating conditions.

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
