Polytetraflouroethylene (TFE) and PVDF both are on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) along with PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide requirement for this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilized within dozens of purposes from non-stick fry griddles to ptfe tape for personal use. This mineral is actually a crucial raw material within the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This increased demand bundled with shortage of raw materials is responsible for a dramatic price increase (almost double over the past year), shortages, and we expect both these factors to keep at it in the near future.
