Polytetraflouroethylene (TFE) and PVDF are both experiencing long lead times.
Teflon product PTFE (TFE) along with PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide requirement for this mineral has risen significantly, as well as supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilised in a great deal of applications from non-stick fry griddles to ptfe tape for use at home. This particular mineral is actually a crucial raw material within the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This surge in demand coupled with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the past year), shortages, and we expect both these factors to stay in affect in the near future.
