Teflon (TFE) and Kynar - PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide demand for this mineral has risen significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilized within a great deal of purposes from non-stick fry kitchenware to ptfe tape for use at home. This particular mineral is actually a important raw materials inside the manufacturing of fluoropolymers, fluorolubricants and quite a few refrigerants.This increased demand combined with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the last year), shortages, and we expect these two factors to stay in affect in the near future.
