PTFE (TFE) and Kynar - PVDF both are on allocation.
PTFE - Polytetrafluoroethylene product PTFE (TFE) along with Kynar-PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world demand for this mineral has increased significantly, and also the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is utilised in dozens of purposes from non-stick fry pans to ptfe tape for home use. This particular mineral is actually the crucial raw material within the production of fluoropolymers, fluorolubricants and several refrigerants.This rise in demand paired with shortage of raw materials is responsible for 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.
