Polytetraflouroethylene (TFE) and Kynar are both on allocation.

PTFE - Polytetrafluoroethylene  product PTFE (TFE) as well as Kynar  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world demand for this mineral has grown significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilised throughout tons of purposes from non-stick fry pots and pans to ptfe tape for home use. This specific mineral is a crucial raw materials in the production of fluoropolymers, fluorolubricants and many refrigerants.This increased demand mixed with general shortage of raw materials is 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.
