PTFE (TFE) and PVDF are both on allocation.
PTFE - Polytetrafluoroethylene products, PTFE (TFE) as well as PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world need for this mineral has grown 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 utilized within a lot of applications from non-stick fry pots and pans to ptfe tape for home use. This specific mineral is a crucial raw material within the production of fluoropolymers, fluorolubricants and a lot of refrigerants.This increasing amount of demand linked with general shortage of raw materials is 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.
