Polytetraflouroethylene (TFE) and Kynar - PVDF are both on allocation.
TFE sheet products, PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world need for this mineral has grown significantly, as well as supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilized throughout a great deal of purposes from non-stick fry kitchenware to ptfe tape for use at home. This mineral is actually the critical raw material within the production of fluoropolymers, fluorolubricants and many refrigerants.This escalating demand linked with shortage of raw materials is responsible for a dramatic price increase (almost double during the last year), shortages, and we expect these two factors to stay in affect in the near future.
