PTFE (TFE) and PVDF both are in short supply.
Teflon product PTFE (TFE) as well as PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has risen significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slippery) and is utilised in a good deal of applications from non-stick fry pots and pans to ptfe tape for home use. This particular mineral is the critical raw materials inside the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This increase in demand coupled with shortage of raw materials has caused a dramatic price increase (almost double throughout the last year), shortages, and we expect these two factors to keep at it in the near future.
