Teflon (TFE) and PVDF both are on allocation.
TFE sheet products, PTFE (TFE) as well as PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide requirement for this mineral has grown significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is utilized within a bunch of applications from non-stick fry cookware to ptfe tape for use at home. This particular mineral is the critical raw material within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This rise in demand bundled with general shortage of raw materials is responsible for a dramatic price increase (almost double in the last year), shortages, and we expect both these factors to stay in affect in the near future.
