PTFE (TFE) and PVDF both are on allocation.
PTFE - Polytetrafluoroethylene product PTFE (TFE) and also 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 heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilized throughout a great deal of purposes from non-stick fry cookware to ptfe tape for use at home. This mineral is a critical raw materials inside the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This rise in demand combined with shortage of raw materials has caused a dramatic price increase (almost double within the last year), shortages, and we expect both these factors to stay in affect in the near future.
