Product Details


AKTIFIT VM is an activated SILFIT Z 91, produced by modifying the surface with a special vinyl functional group. The by-products split off during the treatment reaction are largely removed during the production process which firmly attaches the functional group to the filler surface. This
helps minimize undesirable side effects, as they are potentially encountered with in-situ mixing (direct addition of additive to the compound).
A special process technology during production of AKTIFIT VM provides high hydrophobicity as well as outstanding low moisture absorption even under very humid conditions. During compounding, the hydro-phobic vinyl groups groups of AKTIFIT VM ensure good wetting and excellent dispersion in the matrix polymer. In addition, in polymers with suitable functional groups and presence of free radicals, i. e. peroxides, Aktifit VM can be covalently bonded into the polymeric matrix.
