Polytetraflouroethylene (TFE) and PVDF are both experiencing long lead times.
PTFE - Polytetrafluoroethylene product PTFE (TFE) as well as PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world demand for this mineral has grown significantly, and 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 great deal of applications from non-stick fry cookware to ptfe tape for use at home. This particular mineral is a essential raw material in the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This surge in demand paired with shortage of raw materials is responsible for a dramatic price increase (almost double in the last year), shortages, and we expect both these factors to continue in the near future.
