Aktisil VE is an activated Sillitin Z 86, produced by modifying the surface with Vinyl silane. The by-products split off during the treatment reaction are largely removed during the production process which firmly attaches the silane to the filler surface. This helps minimize undesirable side effects, as they are potentially encountered with in-situ mixing. During the vulcanization the vinyl groups of the Aktisil VE react in the presence of radicals with the polymer.
* Application:
In Elastomer application Aktisil VE can be used as a functional filler either on its own or in combination with other non-reinforcing or reinforcing fillers. The best effect is achieved in radical cured systems. It can be used whenever high tensile strength and high modulus, combined with low tensile and compression set, are as important as excellent processing and extrusion properties. These properties are an ideal combination, in particular for pressure-less cured extruded products and sponge rubber. |
