Polytetraflouroethylene (TFE) and Kynar are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and also Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world demand for this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is used throughout a bunch of applications from non-stick fry cookware to ptfe tape for home use. This mineral is a essential raw materials inside the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This escalating demand combined 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 keep at it in the near future.
