SIL
(S102-R85, MVQ, Silicon, Ecosil)
An elastomer on the basis of methyl vinyl silicon rubber. It is used for O-rings and flat and special seals. It is used mainly for static /rest/ seals. It has a very good resistance to high temperatures, ozone and aging processes. Its mechanical properties are lower than mechanical properties of "rubber" materials.
