Polytetraflouroethylene (TFE) and Kynar - PVDF are both on allocation.
PTFE – Polytetrafluoroethylene product PTFE (TFE) and also Kynar manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide need for this mineral has increased significantly, along with the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is used throughout tons of applications from non-stick fry griddles to ptfe tape for home use. This specific mineral is a essential raw material in the manufacturing of fluoropolymers, fluorolubricants and several refrigerants.This increased demand linked with general shortage of raw materials is mainly 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.
