Aktifit VM in hydraulic and fuel hoses

Peroxide

Calcined product, vinyl functionalized.

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

very good extrusion properties

high surface quality

high tensile modulus

low compression set

good resistance against fuels, oil, water, acid

avoids deposits on dies caused by filler
