Polytetrafluoroethylene_(PTFE)

polymer

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer known for its exceptional chemical inertness, low friction surface, and broad temperature stability. It is widely used in chemical processing equipment, non-stick coatings, seals, gaskets, and pipeline linings where resistance to corrosive fluids and extreme temperatures is critical. PTFE's unique combination of lubricity and chemical resistance makes it the default choice for applications where conventional polymers would degrade, though its higher cost and processing complexity compared to standard thermoplastics limit its use to situations where performance demands justify the investment.

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.
