Polytetraflouroethylene (TFE) and Kynar - PVDF are both in short supply.
PTFE - Polytetrafluoroethylene product PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world need for this mineral has risen significantly, and the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is used in a great deal of purposes from non-stick fry griddles to ptfe tape for personal use. This particular mineral is actually a critical raw materials inside the production of fluoropolymers, fluorolubricants and many refrigerants.This surge in demand combined with shortage of raw materials is mainly responsible for a dramatic price increase (almost double in the last year), shortages, and we expect these two factors to continue in the near future.
