Teflon (TFE) and Kynar are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and also Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world demand for this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilized in a great deal of purposes from non-stick fry kitchenware to ptfe tape for use at home. This particular mineral is actually a crucial raw material in the production of fluoropolymers, fluorolubricants and several refrigerants.This increase in demand linked with shortage of raw materials is responsible for a dramatic price increase (almost double during the last year), shortages, and we expect both these factors to keep at it in the near future.
