Silicon fluorine rubber sealing ring manufacturer

Fluororubber has excellent aging resistance and ozone resistance. According to the report, VitonA, developed by DuPont, was still satisfactory after 10 years of natural storage, with no obvious cracking after 45 days in air with ozone concentration of 0.01%. Type 23 fluororubber has excellent weather resistance and ozone resistance.

Vacuum performance

Model 26 fluoro rubber has excellent vacuum properties. The vacuum discharge rate of fluororubber by potassium pump per second was only 37×10-6. 2 cm. Model 246 fluororubber has been successfully used in the vacuum condition of 10-9 pumps.

Mechanical properties of

Fluoro rubber has excellent physical and mechanical properties. The general strength of type 26 fluororubber is between 10 mpa and 20MPa, the elongation at break is between 150 and 350%, and the tear strength is between 3 and 4KN/m. Type 23 fluororubber has a strength of 15.0~25MPa, a elongation of 200%~600%, and a tear strength of 2~7MPa. Generally speaking, the compression permanent deformation of fluoro rubber at high temperature is large, but if comparing with the same conditions, such as the compression permanent deformation of fluoro rubber at 150℃ for the same time, both butyl and neoprene rubber are larger than type 26 fluoro rubber, and the compression deformation of type 26 fluoro rubber at 200℃×24 hours is equivalent to that of butyl rubber at 150℃×24 hours.

electrical

Type 23 fluororubber has better electrical properties and lower hygroscopicity than other elastomers. Type 26 rubber can be used at low frequency and low pressure.

Permeability is small

Fluororubber has a higher solubility to gas, but a lower diffusion rate, so the overall air permeability is also small. It is reported that the air permeability of type 26 fluoro rubber to oxygen, nitrogen, helium and carbon dioxide at 30℃ is equal to that of butyl rubber and butadiene rubber, and better than that of neoprene and natural rubber.
