Why is there PTFE and Kynar- PVDF extended delivery

Throughout the last year, the business has had more challenges than I've come across around my 30 years experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery problems resulting from resin allocations by resin vendors. This is actually the very first instance I have seen all these issues at the same time.

Polytetraflouroethylene (TFE) and Kynar are both on allocation.

The two of these resins are in short supply. The  PTFE Sheet suppliers product PTFE (TFE) along with PVDF  manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide interest in this mineral has grown significantly, along with the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is used throughout a bunch of applications from non-stick fry pans to ptfe tape for personal use. This mineral is actually a important raw materials within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This increased demand combined with general shortage of raw materials is responsible for a dramatic price increase (almost double over the last year), shortages, and we expect both these factors to continue in the near future.
