            時間:2014/11/14 13:48:48   From:   View:2316

              The chemical structure of ptfe is all hydrogen atoms replaced in the polyethylene. In fluorine plastic, ptfe consumption is the largest, most versatile, it is a very important part in fluorine plastic varieties.

              Ptfe advantages:

              High temperature resistant, use the working temperature of 250 ℃.

              Good low temperature resistance, good mechanical toughness; Even if the temperature drops to 196 ℃, also can keep 5% elongation.

              Corrosion - to most chemicals and solvents, inert, acid alkali, water and a variety of organic solvents.

              Weather - to be the best in the plastic in aging life.

              High lubrication - is the lowest in the friction coefficient in solid materials.

            Don't stick - is the smallest, the surface tension of the solid material don't adhere to any material.

              Non-toxic, has a physiological inertia, long as artificial blood vessels and organs implanted without adverse reaction.

              Teflon commonly known as "plastics king". It has excellent chemical stability, high corrosion resistance, sealing, lubrication is not sticky, electric insulation and good anti-aging endurance. At + 250 ℃ to 180 ℃ under the temperature of working for a long time, all kinds of ptfe products have been in the chemical industry, machinery, electronics, electrical, military, aerospace, environmental protection and Bridges and other fields of national economy has played a pivotal role.
