Polytetraflouroethylene (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as Kynar manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world demand for this mineral has risen 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 griddles to ptfe tape for personal use. This specific mineral is the essential raw material in the manufacturing of fluoropolymers, fluorolubricants and several refrigerants.This surge in demand joined together with shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the past year), shortages, and we expect both these factors to continue in the near future.
