Features & Benefits

Benefits

A further benefit which will result from the application of Silanogran HVS is the outstanding influence on physical and electrical properties of rubber compounds. Tests in our rubber lab showed that a dosage of only 50 % of the original silane quantity (tris-(2-methoxyethoxy-) vinyl silane led to better values for physical properties as well as for aging properties.

Uses

Silanes are used to improve processability and physical properties of rubber vulcanizates. In com-pounds which are used for cable isolation silanes are applied as hydrophobing agent. In bright per-oxide cured rubber compounds the most common used agent is tris-(2-methoxyethoxy-)vinyl silane (e. g. A-172, GF 58, VTMOEO).

Dosage

These results have been proved by tests of some of our customers. The possibility to reduce the silane dosage in such a significant way may also help to save money.
