How come there's a Teflon and PVDF extended delivery times

In the last year, the business has had more difficulties than I have come across within my 3 decades experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery problems as a result of resin allocations from resin manufacturers. This is the first occasion I have seen all these issues at one time.

PTFE (TFE) and Kynar - PVDF both are on allocation.

This pair of resins are in short supply. The  PTFE Sheet suppliers product PTFE (TFE) and also Kynar  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world requirement for this mineral has grown significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and incredibly low co-efficient of friction (slick) and is utilised in tons of purposes from non-stick fry cookware to ptfe tape for personal use. This mineral is a essential raw materials in the production of fluoropolymers, fluorolubricants and many refrigerants.This rise in demand joined together with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the past year), shortages, and we expect these two factors to keep at it in the near future.
