Teflon (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as Kynar manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world requirement for this mineral has risen significantly, as well as supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slippery) and is utilized throughout a lot of purposes from non-stick fry cookware to ptfe tape for personal use. This particular mineral is actually the critical raw materials inside the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This increased demand combined with shortage of raw materials is responsible for a dramatic price increase (almost double over the last year), shortages, and we expect these two factors to keep at it in the near future.
