Key statement: A rubber composition comprising (A) an
organopolysiloxane end-capped with alkenyldialkylsiloxy, radicals and
free of aliphatic unsaturation, (B) an organipolysiloxane containing
three alkenyl radicals on molecular side chains, (C) an
organohydrogenpolysiloxane, (D) fumed silica and (E) an addition
reaction catalyst forms a seal member having improved strength and
reduced compression set and useful for sealing a polymer electrolyte
fuel-cell separator. One highlight will be a novel aliphatic PUR cast elastomer
technology said to enable production of highly transparent parts with
unique property profiles. What's more, these
transparent materials, based on aliphatic isocyanates and polyesters,
can be pigmented with any color. |
