Aktisil VM 56/89 in molded gaskets, o-rings and radial shaft seals

Peroxide

Vinyl functionalized based on Sillitin Z 89.

Aktisil VM 56/89 is suitable for greater color neutrality requirements and slightly improved dispersion.

very low sieve residue

good mixing and dispersion properties

long flow time with short vulcanization time

easy deflashing

low compression set

good media resistance (fuel, oil, water, acid)
