- Application Details
Cable insulations for household, automotive, railway, marine and aerospace applications where high flame retardancy is required.. 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.
