Teflon (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene product PTFE (TFE) and also Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world demand for this mineral has grown significantly, and also the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is used within a bunch of purposes from non-stick fry kitchenware to ptfe tape for personal use. This mineral is actually the important raw materials in the manufacturing of fluoropolymers, fluorolubricants and quite a few refrigerants.This escalating demand coupled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double during the last year), shortages, and we expect these two factors to keep at it in the near future.
