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