Polytetraflouroethylene (TFE) and Kynar - PVDF both are experiencing long lead times.
Teflon product PTFE (TFE) along with Kynar manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has increased significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilised in dozens of purposes from non-stick fry cookware to ptfe tape for home use. This mineral is actually a crucial raw material inside the production of fluoropolymers, fluorolubricants and many refrigerants.This increasing amount of demand joined together with shortage of raw materials has caused a dramatic price increase (almost double over the past year), shortages, and we expect both these factors to continue in the near future.
