- Application Details
The grade is suitable for the manufacture of articles like cable accessories e. g. joints, terminations or single sheds for outdoor applications. Specially thick walled articles can take advantage of the fast curing material.
- Outdoor or indoor cable terminations
- Silicone sheds
Processing
POWERSIL® 3500 MH is to be press cured. The material can be processed on conventional silicone rubber injection molding equipment. Caution, danger of deactivation! The Pt-catalyst can be deactivated already via air e.g. by amines, sulfur compounds.
