PTFE - Polytetrafluoroethylene product PTFE (TFE) and also Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide interest in this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized in a good deal of purposes from non-stick fry pots and pans to ptfe tape for use at home. This specific mineral is actually the critical raw material within the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This increase in demand combined with general shortage of raw materials is responsible for a dramatic price increase (almost double within the last year), shortages, and we expect both these factors to continue in the near future.
