poly(tetrafluoroethylene-co-2,2-bis(trifluoromethyl)-4,5-difluoro-1,3-dioxole)

polymer

This is a specialty perfluoropolymer copolymer combining tetrafluoroethylene (PTFE) with a perfluorinated dioxole monomer, engineered to achieve enhanced thermal stability and chemical resistance beyond standard PTFE. It belongs to the family of high-performance fluoropolymers developed for extreme-condition applications where conventional fluoropolymers reach their performance limits, and is typically found in aerospace, chemical processing, and semiconductor manufacturing where exceptional thermal stability, non-reactivity, and dimensional consistency are critical.

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.
