PTFE - Polytetrafluoroethylene product PTFE (TFE) and Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world need for this mineral has increased significantly, as well as the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is used in tons of applications from non-stick fry griddles to ptfe tape for home use. This specific mineral is actually a essential raw materials inside the production of fluoropolymers, fluorolubricants and many refrigerants.This increasing amount of demand paired with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the past year), shortages, and we expect both these factors to continue in the near future.
