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

Peroxide

Vinyl functionalized based on Sillitin Z 86.

Aktisil VM 56 is applicable specially for peroxide crosslinking.
The product offers higher tensile strength, higher tensile modulus and lower compression set as well as better abrasion resistance and improved chemical resistances.

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)
