PTFE (TFE) and PVDF both are in short supply.

PTFE - Polytetrafluoroethylene  product PTFE (TFE) and also Kynar-PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world demand for this mineral has increased 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 utilised throughout tons of purposes from non-stick fry griddles to ptfe tape for personal use. This particular mineral is actually the essential raw material in the production of fluoropolymers, fluorolubricants and several refrigerants.This escalating demand linked with shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the past year), shortages, and we expect these two factors to continue in the near future.
