What caused the TFE and Kynar- PVDF long lead times
During the last year, the market has experienced more shortages than I've come across in my three decades experience. In the past I have seen sharp price increases, and I have witnessed several shortages, and delivery problems on account of resin allocations by plastic resin companies. This is actually the very first occasion I have seen all these issues at one time. PTFE Sheet (TFE) and PVDF are both on allocation. These two resins are in short supply. The PTFE Sheeting product PTFE (TFE) and Kynar-PVDF manufacturing requires a mineral called Fluorspar that is mined in Mongolia and China. The world demand for this mineral has risen significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilised in tons of applications from non-stick fry cookware to ptfe tape for use at home. This specific mineral is a important raw materials within the manufacturing of fluorop...
