Description & Usage

PTFE is the “ultimate” filter medium for the most aggressive industrial environments. It is chemically inert, meaning it is unaffected by almost all acids, alkalis, and solvents. Its naturally low-friction surface allows for excellent cake release during cleaning cycles. While it is the most expensive option, its ability to survive in conditions that would destroy any other synthetic fiber makes it essential for specialized high-heat chemical processing.
