PTFE (TFE) and Kynar - PVDF both are on allocation.
TFE sheet products, PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has risen significantly, and the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized in a good deal of applications from non-stick fry cookware to ptfe tape for use at home. This mineral is actually the crucial raw materials within the production of fluoropolymers, fluorolubricants and a lot of refrigerants.This rise in demand paired with general shortage of raw materials is responsible for a dramatic price increase (almost double within the last year), shortages, and we expect these two factors to stay in affect in the near future.
