Polytetraflouroethylene (TFE) and Kynar both are on allocation.

PTFE - Polytetrafluoroethylene  products, PTFE (TFE) along with Kynar  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide demand for this mineral has increased significantly, and also the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized throughout a good deal of purposes from non-stick fry pans to ptfe tape for personal use. This mineral is a important raw materials within the manufacturing of fluoropolymers, fluorolubricants and several refrigerants.This increase in demand joined together with general shortage of raw materials is responsible for a dramatic price increase (almost double within the past year), shortages, and we expect these two factors to keep at it in the near future.
