Teflon (TFE) and PVDF both are on allocation.

TFE sheet  products, PTFE (TFE) as well as Kynar  manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world demand for this mineral has grown significantly, along with the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slick) and is utilized within a good deal of purposes from non-stick fry griddles to ptfe tape for use at home. This mineral is actually the key raw materials inside the production of fluoropolymers, fluorolubricants and several refrigerants.This surge in demand combined with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the last year), shortages, and we expect both these factors to continue in the near future.
