Polytetraflouroethylene (TFE) and Kynar - PVDF both are on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world requirement 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 (slippery) and is used throughout a bunch of applications from non-stick fry griddles to ptfe tape for personal use. This particular mineral is the essential raw material within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This rise in demand bundled with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the last year), shortages, and we expect both these factors to keep at it in the near future.
