DESCRIPTIONAn economic grade based on a mixture of aramid and glass fibres, with a nitrile rubber binder. Klingersil C4400 also has an anti-stick finish on both sides.
SERVICEGood resistance to: oils, hydrocarbons and low pressure steam and water. Very successful in internal combustion engine applications.
Max recommended temperature : OPERATING 400°C
Max recommended temperature : OPERATING STEAM 150°C
Max recommended pressure : 65 BAR
These temperature and pressure guides cannot necessarily be used simultaneously and may not apply to all thicknesses. The operating temperature for non-asbestos sheet materials is related to the thickness of the material. Thinner materials offer better temperature and pressure properties.
