PTFE (TFE) and PVDF both are in short supply.
Teflon product PTFE (TFE) and also PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide interest in this mineral has increased significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilised within dozens of applications from non-stick fry pots and pans to ptfe tape for personal use. This specific mineral is actually a crucial raw material in the production of fluoropolymers, fluorolubricants and lots of refrigerants.This escalating demand paired with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the last year), shortages, and we expect these two factors to stay in affect in the near future.
