Polytetraflouroethylene (TFE) and Kynar - PVDF are both on allocation.

PTFE - Polytetrafluoroethylene  products, PTFE (TFE) and also PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide interest in this mineral has grown significantly, as well as supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is used throughout a great deal of applications from non-stick fry pans to ptfe tape for use at home. This specific mineral is a essential raw material inside the production of fluoropolymers, fluorolubricants and lots of refrigerants.This escalating demand paired with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double throughout the last year), shortages, and we expect these two factors to continue in the near future.
