PTFE (TFE) and PVDF both are on allocation.
PTFE - Polytetrafluoroethylene product PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world need for this mineral has grown significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slick) and is used within a good deal of purposes from non-stick fry cookware to ptfe tape for home use. This mineral is actually a essential raw material within the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This surge in demand linked with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double in the last year), shortages, and we expect these two factors to stay in affect in the near future.
