How come there's a TFE and Kynar extended delivery times

Over the past year, the business has had more shortages than I've come across inside my three decades experience. In the past I have seen sharp price increases, and I have experienced several shortages, and delivery delays because of resin allocations from resin manufacturers. This is the very first occasion I have seen all these issues at the same time.

PTFE (TFE) and PVDF both are on allocation.

These two resins are in short supply. The  PTFE Sheet suppliers product PTFE (TFE) and PVDF  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The world requirement for this mineral has risen significantly, additionally, the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and very low co-efficient of friction (slippery) and is utilised in tons of applications from non-stick fry griddles to ptfe tape for personal use. This particular mineral is actually a critical raw material inside the manufacturing of fluoropolymers, fluorolubricants and quite a few refrigerants.This escalating demand paired with general shortage of raw materials has caused a dramatic price increase (almost double throughout the last year), shortages, and we expect both these factors to keep at it in the near future.
