Polytetraflouroethylene (TFE) and Kynar - PVDF both are on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world requirement for this mineral has grown significantly, and the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is used within a bunch of purposes from non-stick fry pots and pans to ptfe tape for use at home. This mineral is a important raw materials within the production of fluoropolymers, fluorolubricants and several refrigerants.This increasing amount of demand coupled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double throughout the last year), shortages, and we expect both these factors to stay in affect in the near future.
