PTFE (TFE) and PVDF are both on allocation.

PTFE - Polytetrafluoroethylene  product PTFE (TFE) and Kynar-PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilized in a good deal of applications from non-stick fry pots and pans to ptfe tape for personal use. This mineral is actually a important raw material in the production of fluoropolymers, fluorolubricants and several refrigerants.This rise in demand combined with general shortage of raw materials has caused a dramatic price increase (almost double within the last year), shortages, and we expect these two factors to keep at it in the near future.
