Why is there Teflon and Kynar- PVDF extended delivery

Within the last year, the market has experienced more shortages than I've come across in my thirty years experience. In the past I have seen sharp price increases, and I have witnessed several shortages, and delivery problems caused by material allocations by resin vendors. This is the first instance 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 Sheeting product PTFE (TFE) along with Kynar-PVDF  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide interest in this mineral has grown significantly, and the supply has tightened. PTFE materials have high temperature resistance, excellent chemical resistance and extremely low co-efficient of friction (slick) and is used within a great deal of purposes from non-stick fry griddles to ptfe tape for home use. This particular mineral is actually a critical raw materials in the production of fluoropolymers, fluorolubricants and a lot of refrigerants.This surge in demand linked with general shortage of raw materials is mainly responsible for a dramatic price increase (almost double over the past year), shortages, and we expect both these factors to continue in the near future.

Bayer Makrolon Polycarbonate Flat Sheet offering light weight and break resistance

Polycarbonate materials offer a balance of useful features including high temperature resistance, impact resistance and optical properties position polycarbonates in between commodity plastic materials and engineering materials. Polycarbonate is a very sturdy material. Whilst it offers higher impact-resistance, it's got a lower scratch-resistance and thus a hard coating is often applied to polycarbonate eyeglasses lenses and polycarbonate exterior motor vehicle equipment. The characteristics associated with polycarbonate are generally along the lines of those of Acrylic PMMA materials, although polycarbonate is actually stronger, it is usable in a wider temperature range and is a bit more expensive. This plastic polymer is highly transparent to visible light and it has better light transmission characteristics than many different types of glass. Polycarbonate carries a glass transition temperature near 150 °C (302 °F), consequently it softens slowly above this point and flows above
