What Is The Biggest Drawback Of Raw Materials Of PTFE Filler?

Jun 24, 2018

The biggest disadvantage of raw materials of PTFE filler: it is not easy to degrade. Because  PTFE is excellent in various adverse environments such as acid and  alkali resistant to oxidation reduction and high temperature resistance,  it is one of the most chemically stable plastics, so PTFE waste is not  good to deal with, resulting in more white pollution. Powerful. So this is its biggest drawback.

PTFE  has high corrosion resistance to strong acids, strong alkalis, and  strong oxidants. Even if the temperature is high, it will not work. Its  corrosion resistance even exceeds that of glass, ceramics, stainless  steel, and even gold and platinum. PTFE  has a carbon atom as the skeleton. Fluorine atoms are distributed  symmetrically and evenly around it, forming a tight barrier and giving  it very valuable comprehensive physical and mechanical properties. PTFE is one of the fluorine plastics used for sealing. Except  that some aromatic compounds can slightly swell PTFE, they have  corrosion resistance to ketones, alcohols and other organic solvents. Only molten alkali metals and elemental fluorine can work at high temperatures.
If there are oil stains or dirt, you can use alkaline cleaners. If it is rust, chemical residues, you can use acid to clean. Chemical  resistance and weather resistance In addition to the molten alkali  metal, PTFE is hardly corroded by any chemical agents. PTFE  does not absorb moisture, is not flammable, and is extremely stable  against oxygen and ultraviolet rays, so it has excellent weather  resistance. All  types of PTFE products have played a pivotal role in the national  economy such as chemical engineering, machinery, electronics, electrical  appliances, military industry, aerospace, environmental protection, and  bridges.
