The world need for this mineral has risen significantly, and also the supply has tightened. PTFE materials have high heat resistance, excellent chemical resistance and extremely low co-efficient of friction (slippery) and is used in a good deal of purposes from non-stick fry pans to ptfe tape for personal use. This particular mineral is actually a critical raw materials inside the...
