Polytetraflouroethylene (TFE) and PVDF both are on allocation.

Teflon  product PTFE (TFE) and also Kynar  manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world requirement for this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilized throughout a lot of purposes from non-stick fry kitchenware to ptfe tape for personal use. This mineral is actually the essential raw materials in the manufacturing of fluoropolymers, fluorolubricants and quite a few refrigerants.This increased demand coupled with shortage of raw materials is responsible for a dramatic price increase (almost double over the past year), shortages, and we expect these two factors to continue in the near future.
