Application Details

Technical molding and extrusion for general purpose applications.. The raw rubber requires the addition of peroxides for vulcanization at elevated temperatures. A homogeneous incorporation is a must, but please avoid temperatures >30°C along the incorporation process in order to maintain best processing behavior. Pot life is depending on the used peroxide and storage condition.

Storage Information

Please store the cardboard boxes in a dry and cool place. Already opened boxes should be closed again to avoid any contamination.
