Polytetraflouroethylene (TFE) and Kynar are both 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 requirement for this mineral has risen significantly, and the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilized within tons of purposes from non-stick fry pans to ptfe tape for personal use. This specific mineral is actually a crucial raw material in the production of fluoropolymers, fluorolubricants and quite a few refrigerants.This increased demand combined with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the last year), shortages, and we expect both these factors to keep at it in the near future.
