Teflon (TFE) and Kynar are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world requirement for this mineral has grown significantly, as well as the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slippery) and is utilized in a great deal of purposes from non-stick fry griddles to ptfe tape for home use. This specific mineral is actually the critical raw material within the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This rise in demand mixed with general shortage of raw materials is 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.
