Polytetraflouroethylene (TFE) and Kynar - PVDF both are experiencing long lead times.
PTFE - Polytetrafluoroethylene product PTFE (TFE) along with Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has risen significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized in a bunch of purposes from non-stick fry pots and pans to ptfe tape for use at home. This particular mineral is actually a crucial raw materials inside the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This rise in demand linked with general shortage of raw materials has caused a dramatic price increase (almost double in the last year), shortages, and we expect these two factors to continue in the near future.
