PTFE (TFE) and PVDF both are on allocation.
TFE sheet products, PTFE (TFE) as well as Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world interest in this mineral has increased significantly, and the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilized within a bunch of applications from non-stick fry kitchenware to ptfe tape for home use. This particular mineral is actually a important raw materials within the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This escalating demand mixed with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double in the last year), shortages, and we expect both these factors to continue in the near future.
