Polytetraflouroethylene (TFE) and Kynar are both experiencing long lead times.
PTFE - Polytetrafluoroethylene product PTFE (TFE) along with Kynar manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide requirement for this mineral has increased significantly, along with the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilised in dozens of applications from non-stick fry pans to ptfe tape for use at home. This specific mineral is the critical raw materials within the production of fluoropolymers, fluorolubricants and many refrigerants.This surge in demand coupled with shortage of raw materials has caused a dramatic price increase (almost double throughout the last year), shortages, and we expect both these factors to continue in the near future.
