How come there's a PTFE and Kynar- PVDF extended delivery times

During the last year, the market has experienced more challenges than I've come across inside my three decades experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery problems as a consequence of material allocations from plastic resin suppliers. This is definitely the first time I have seen all these issues at one time.

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

These two resins are in short supply. The  PTFE Sheet product PTFE (TFE) and also Kynar-PVDF  manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The worldwide demand for this mineral has increased significantly, additionally, the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and really low co-efficient of friction (slippery) and is utilized within tons of purposes from non-stick fry cookware to ptfe tape for use at home. This particular mineral is a important raw materials within the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This increased demand coupled with 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 keep at it in the near future.
