PTFE (TFE) and Kynar - PVDF are both in short supply.
Teflon product PTFE (TFE) and Kynar manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide demand for this mineral has increased significantly, as well as supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slippery) and is utilized in dozens of applications from non-stick fry kitchenware to ptfe tape for home use. This specific mineral is actually a key raw materials in the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This rise in demand joined together with shortage of raw materials has caused a dramatic price increase (almost double within the last year), shortages, and we expect these two factors to keep at it in the near future.
