3. Name Short Description
SILFIT Z 91 Same as Sillitin N 85, but with avoidance of mold fouling caused by filler,
greater brightness and color neutrality, less moisture content, improved
dispersion.
Name Short Description
AKTISIL MM Same as Sillitin Z 86, but with higher tensile strength, higher tensile
modulus and lower compression set, better abrasion resistance, improved
chemical resistance.
AKTISIL PF 216 Same as Aktisil MM, but with highest tensile strength and tensile modulus,
lowest compression set, best abrasion resistance, best chemical resistance.
AKTIFIT AM Same as Silfit Z 91, but with higher tensile strength, higher tensile
modulus and lower compression set, better abrasion resistance, improved
resistance.
Name Short Description
AKTISIL VM 56 Same as Sillitin Z 86, but with higher tensile strength, higher tensile
modulus and lower compression set, better abrasion resistance, improved
chemical resistance.
AKTISIL VM 56/89 Same as Aktisil VM 56, but for greater color neutrality requirements and
slightly improved dispersion.
AKTISIL Q Similar to Aktisil VM 56/89 but with less moisture content, lower viscosity,
lower compression set, improved resistance, best product for silicone
rubber.
AKTIFIT VM Same as Silfit Z 91, but with higher tensile strength, higher tensile
modulus and lower compression set, better abrasion resistance, improved
chemical resistance.
