Asbestos Free(AF) Fibre Jointing Sheets - AF K11

Optimum combination of aramid fibre bonded with special elastomeric binders

Champion Jointing Style AF K11 is a superior performance, high dielectric strength compressed asbestos-free (AF) universal jointing sheet consisting of premium grade of synthetic aramid fibers, with special performance elastomers, additives and specialty chemicals. The materials are specially formulated to act as insulator or barrier to flow of electrons from one flange to another. Champion Jointing AF K11 Sheets are available in non-metallic (i.e. without wire reinforced) This grade is produced in cream / off white.

Champion Jointing AF K11 has excellent creep resistance at elevated temperature and is used as gasket for universal applications. It has very high Dielectric Strength which makes it ideal insulating material.

Suitable for use with oils, water, steam, gases, salt solutions, fuels, alcohols, moderate organic and inorganic acids, hydrocarbons, lubricants and refrigerants, food industry.

Sheets, pre-cut gaskets, special density, thickness, shape or grade available on request.
