Teflon (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as Kynar manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide need for this mineral has grown significantly, additionally, the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is used within a lot of applications from non-stick fry pans to ptfe tape for personal use. This particular mineral is actually the crucial raw materials inside the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This increase in demand mixed with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double during the last year), shortages, and we expect these two factors to keep at it in the near future.
