Champion Gasket Style AF 139

Compressed Fibre Jointing Sheet With Aramid and Inorganic Fibres with NBR Binder

Compressed fibre jointing sheet with aramid and inorganic fibres with NBR binder

Champion Jointing Style AF 139 is higher performance BS7531 Grade-X Asbestos-Free (AF) Jointing sheet. It is comprised of compressed aramid fibres and bonded with a combination of functional fibres with a nitrile rubber binder to create a matrix of stability for thermal and chemical medium service.

Champion AF 139 Sheets are available in non-metallic and also in metallic option (with wire re-inforcement and anti-stick properties- which minimizes adhesion of the gasket to flange surfaces even at elevated temperatures, resulting in reduced removal time). This grade is produced in orange color.
