PTFE - Polytetrafluoroethylene products, PTFE (TFE) and also Kynar manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide requirement for this mineral has increased significantly, and the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilized throughout dozens of applications from non-stick fry kitchenware to ptfe tape for use at home. This particular mineral is a important raw material in the production of fluoropolymers, fluorolubricants and lots of refrigerants.This surge in demand joined together with general shortage of raw materials is responsible for a dramatic price increase (almost double in the last year), shortages, and we expect these two factors to continue in the near future.
