Polytetraflouroethylene (TFE) and Kynar both are on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) and PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide interest in this mineral has grown significantly, as well as supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilized in a lot of applications from non-stick fry griddles to ptfe tape for personal use. This particular mineral is the essential raw materials in the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This rise in demand linked with general shortage of raw materials is responsible for a dramatic price increase (almost double within the past year), shortages, and we expect both these factors to stay in affect in the near future.
