PTFE (TFE) and PVDF are both in short supply.
PTFE - Polytetrafluoroethylene product PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world demand for this mineral has risen significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and really low co-efficient of friction (slick) and is utilised in tons of purposes from non-stick fry pots and pans to ptfe tape for personal use. This particular mineral is a important raw material inside the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This increased demand coupled with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double during the last year), shortages, and we expect both these factors to stay in affect in the near future.
