Why are there PTFE and Kynar are such high priced plastics
Throughout the last year, the business has had more difficulties than I've come across within my 30 years experience. In the past I have seen sharp price increases, and I have seen several shortages, and delivery problems resulting from material allocations by plastic resin manufacturers. This is definitely the first instance I have seen all these issues at one time. PTFE (TFE) and PVDF both are on allocation. The two of these resins are in short supply. The PTFE - Polytetrafluoroethylene product PTFE (TFE) and also Kynar manufacturing requires a mineral called Fluorspar which is mined in Mongolia and China. The world need for this mineral has risen significantly, additionally, the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is utilised throughout a bunch of applications from non-stick fry cookware to ptfe tape for personal use. This particular mineral is the essential raw ma...
