Polytetraflouroethylene (TFE) and Kynar are both on allocation.

TFE sheet  products, PTFE (TFE) and also 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 temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilized within a bunch of purposes from non-stick fry pans to ptfe tape for home use. This mineral is actually a essential raw material in the production of fluoropolymers, fluorolubricants and many refrigerants.This increased demand mixed with shortage of raw materials is responsible for a dramatic price increase (almost double during the last year), shortages, and we expect both these factors to keep at it in the near future.
