Teflon (TFE) and PVDF are both on allocation.

PTFE - Polytetrafluoroethylene  product PTFE (TFE) as well as Kynar-PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide demand for this mineral has increased significantly, as well as supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is used throughout a lot of applications from non-stick fry pots and pans to ptfe tape for personal use. This specific mineral is actually the critical raw material inside the manufacturing of fluoropolymers, fluorolubricants and several refrigerants.This increasing amount of demand bundled with general 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 continue in the near future.
