PTFE (TFE) and Kynar are both experiencing long lead times.
Teflon product PTFE (TFE) and also Kynar-PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide need for this mineral has increased significantly, along with the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilised in tons of applications from non-stick fry pots and pans to ptfe tape for use at home. This particular mineral is actually a important raw materials within the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This increasing amount of 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 continue in the near future.
