What's the reason for the TFE and Kynar- PVDF long lead times

Over the last year, the industry has had more allocations than I have come across inside my thirty years experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery issues resulting from plastic resin allocations through resin manufacturers. This is the very first occasion I have seen all these issues at one time.

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

This pair of 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 demand for this mineral has risen significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is utilised throughout a great deal of applications from non-stick fry pans to ptfe tape for use at home. This specific mineral is actually the important raw material in the production of fluoropolymers, fluorolubricants and many refrigerants.This increase in demand paired with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the last year), shortages, and we expect these two factors to stay in affect in the near future.

Lower Left Back Pain from Internal Organs

It is possible for left-sided back pain to be caused by a problem with one or more internal organs, such as from the kidney or colon. Several common internal causes of lower left back pain include: Kidney Stones.  Lower left back pain from a kidney stone may be felt when a stone moves inside the left kidney, or moves through the ureters, thin tubes connecting the kidneys to the bladder. Other symptoms include pain with urination, difficulty urinating despite a persistent need to do so, blood in the urine, and nausea and/or vomiting. Kidney Infection.  An infection in the left kidney can cause dull or intense lower left back pain. Kidney infections usually start in the urinary tract and bladder, and from there can spread to the kidneys, causing local inflammation and pain in the kidney.

Pain is typically felt next to the spine above the hip, and typically worsens with movement or pressure.
