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

Teflon  product PTFE (TFE) along with PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world need for this mineral has grown significantly, and also the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized in a good deal of applications from non-stick fry cookware to ptfe tape for home use. This specific mineral is actually a critical raw material in the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This rise in 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.
