Polytetraflouroethylene (TFE) and Kynar - PVDF both are in short supply.

Teflon  product PTFE (TFE) and also Kynar-PVDF  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide need for this mineral has increased significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilised within a good deal of applications from non-stick fry cookware to ptfe tape for personal use. This mineral is actually the critical raw material within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This increasing amount of demand bundled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the past year), shortages, and we expect these two factors to continue in the near future.
