Polytetraflouroethylene (TFE) and Kynar - PVDF are both on allocation.
TFE sheet products, PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world requirement for this mineral has increased significantly, additionally, 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 dozens of purposes from non-stick fry pots and pans to ptfe tape for personal use. This specific mineral is actually the key raw materials in the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This rise in demand coupled with general shortage of raw materials has caused a dramatic price increase (almost double over the last year), shortages, and we expect these two factors to continue in the near future.
