PTFE (TFE) and Kynar - PVDF are both on allocation.
TFE sheet products, PTFE (TFE) as well as Kynar manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world need for this mineral has increased significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilized in a great deal of purposes from non-stick fry griddles to ptfe tape for home use. This particular mineral is actually a important raw materials inside the manufacturing of fluoropolymers, fluorolubricants and lots of refrigerants.This increased demand paired with general shortage of raw materials is responsible for a dramatic price increase (almost double within the past year), shortages, and we expect these two factors to stay in affect in the near future.
