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

Sulphur, Metal-oxide

Mercapto functionalized based on Sillitin Z 86.

Aktisil MM is applicable specially for sulphur and metal-oxide crosslinking. The product offers higher tensile strength, higher tensile modulus and
lower compression set even over 100 °C 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)
