Why are there Teflon and Kynar- PVDF long lead times

February 24, 2021

In the last year, the industry has had more allocations than I have come across during my thirty years experience. In the past I have seen sharp price increases, and I have experienced several shortages, and delivery problems because of resin allocations coming from resin vendors. This is actually the first time I have seen all these issues at one time.

PTFE (TFE) and Kynar are both on allocation.

This pair of 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, as well as supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is used within tons of purposes from non-stick fry cookware to ptfe tape for home use. This mineral is actually the essential raw materials in the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This increased demand coupled with general shortage of raw materials is responsible for a dramatic price increase (almost double within the past year), shortages, and we expect both these factors to keep at it in the near future.

When you are searching for a plastic sheet provider you will also wish to investigate the company that you are dealing with to make sure that they are most likely to be around for a long time. If you are going to be having a lot of troubles with your plastic sheet supply you are most likely to wish to ensure that you are going to have the ability to rely on them to remain to offer you with the top quality item that you have involved anticipate, for many years.
