What's the reason for the Teflon and Kynar- PVDF long lead times
Over the past year, the market has experienced more allocations than I have come across during my three decades experience. In the past I have seen sharp price increases, and I have experienced several shortages, and delivery problems caused by plastic resin allocations coming from resin suppliers. This is actually the very first time I have seen all these issues at the same time.
PTFE Sheet (TFE) and PVDF are both on allocation.
Both of these resins are in short supply. The PTFE Sheet suppliers product PTFE (TFE) as well as Kynar manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The worldwide need for this mineral has grown significantly, as well as supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and really low co-efficient of friction (slick) and is utilised within tons of applications from non-stick fry pots and pans to ptfe tape for home use. This specific mineral is actually a essential raw material in the manufacturing of fluoropolymers, fluorolubricants and a lot of refrigerants.This rise in demand paired with shortage of raw materials has caused a dramatic price increase (almost double during the last year), shortages, and we expect these two factors to continue in the near future.
