PTFE (TFE) and Kynar both are experiencing long lead times.
Teflon product PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide need for this mineral has risen significantly, and the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilised throughout a great deal of applications from non-stick fry griddles to ptfe tape for use at home. This mineral is a key raw material in the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This surge in demand bundled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double during the last year), shortages, and we expect both these factors to continue in the near future.
