Processes
Series 22 is a peroxide-cured silicone mixture, processable by extrusion and moulding. It is characterized by offering good stability against steam and resistance to certain aromatic oils (in low dosages). Unlike other standard series, its base colour is RAL 1013 (Translucent). It is a suitable technical solution for autoclave gaskets, moulded parts, and O-rings exposed to mixed temperature and specific fluid conditions.
