PTFE (TFE) and Kynar - PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world need for this mineral has increased significantly, along with the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilized within tons of applications 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 quite a few refrigerants.This escalating demand linked with shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the last year), shortages, and we expect both these factors to keep at it in the near future.
