PTFE (TFE) and Kynar - PVDF are both on allocation.

PTFE - Polytetrafluoroethylene  products, PTFE (TFE) and also PVDF  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world demand for this mineral has increased significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is utilized throughout a great deal of purposes from non-stick fry kitchenware to ptfe tape for home use. This particular mineral is actually a essential raw material in the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This increase in demand coupled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double throughout the last year), shortages, and we expect these two factors to stay in affect in the near future.
