Colorful Fluoroelastomer Rubber Material For Watch Strips
Description:
Because of the high tensile strength/good tear resistance/good waterproof Elastic silicone rubber is very welcome as common watch strip material. But its also have lots of disadvantages for example poor oxidation resistance and ozone resistance, oil resistance and chemical resistance properties are also not good, generally temperature range is about -60-80 degree.
For better solution we found out maybe fluoroelastomer FKM is a better choice for watch strip. Fluoroelastomer FPM material have better heat resistance, better oxidation resistance, better oil and chemical resistance, its really perfect material to cover silicone disadvantages of silicone. Certainly
Fluoroelastomer is the introduction of fluorine atoms in the main or side chain of rubber, thus giving rubber excellent heat resistance, antioxidant, oil resistance, corrosion resistance, perfectly solve the shortcomings of ordinary natural rubber, fluoroelastomer in aerospace, aviation, automotive, petroleum and household appliances and other fields have been widely used, is the defense cutting-edge industry can not replace the key material.
As a strap, in addition to the above advantages, it is higher than the market than ordinary rubber or silicone strap density, more soft, can bend at will, the upper hand feel more unparalleled, will make people feel a hint of the metallic texture of the wire. Wear it with a more close curve to your wrist and better skin comfort.
However, nothing in the world is perfect, fluoroelastomer quality is perfect, but its price is not so perfect, in the same amount of use, its price is about 5-8 times the ordinary rubber strap, at the same time, its production process is more complex, perhaps it is these reasons that it is not widely used.
