PTFE (TFE) and PVDF both are on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world requirement for this mineral has grown significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is utilized in a bunch of purposes from non-stick fry cookware to ptfe tape for home use. This specific mineral is the important raw materials within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This increased demand mixed with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the last year), shortages, and we expect both these factors to keep at it in the near future.
