What is causing the PTFE and Kynar long lead times

Over the last year, the business has had more allocations than I have come across inside my 3 decades experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery issues because of resin allocations through resin manufacturers. This is definitely the first time I have seen all these issues at one time.

Polytetraflouroethylene (TFE) and PVDF are both on allocation.

This pair of resins are in short supply. The  PTFE Sheet suppliers product PTFE (TFE) and PVDF  manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide need for this mineral has risen significantly, additionally, 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 purposes from non-stick fry kitchenware to ptfe tape for personal use. This mineral is the critical raw materials inside the manufacturing of fluoropolymers, fluorolubricants and quite a few refrigerants.This increasing amount of demand combined with general shortage of raw materials has caused a dramatic price increase (almost double within the last year), shortages, and we expect these two factors to keep at it in the near future.
