Aktifit AM in molded gaskets, o-rings and radial shaft seals

Diamine (ACM, AEM)

Calcined product, amino functionalized.

Aktifit AM 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)

avoidance of mold fouling caused by filler
