Polytetraflouroethylene (TFE) and Kynar - PVDF both are in short supply.

Teflon  product PTFE (TFE) and also Kynar-PVDF  manufacturing requires a mineral called Fluorspar that's mined in Mongolia and China. The worldwide need for this mineral has increased significantly, as well as the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and very low co-efficient of friction (slick) and is utilised within a good deal of applications from non-stick fry cookware to ptfe tape for personal use. This mineral is actually the critical raw material within the manufacturing of fluoropolymers, fluorolubricants and many refrigerants.This increasing amount of demand bundled with shortage of raw materials is mainly responsible for a dramatic price increase (almost double within the past year), shortages, and we expect these two factors to continue in the near future.

Is Green DIY Energy A Scam?

Image
It has been shown that renewable energy resources are more resilient in these weather events than fossil fuel dominated sources such as coal, natural gas and nuclear power plants. The dirty coal energy plants can be decommissioned by turning to alternatives to these energy sources. One of these renewable energy resources is solar energy. We need to work together to protect our states from any catastrophic events causing life threatening power outages resulting in higher death tolls But with the latest technology on waste treatment nowadays, biosphere technology is a great help to many countries. If we really want a change we need to start with our homes. Since it undergoes thermal conversion, it does not emit harmful emissions to the atmosphere unlike fossil fuels which are known to be the highest emitter of carbon dioxide. However, photovoltaic cells are not presently as cost effective as "utility produced" electricity By using magnetic generator for electrical energy genera...
