504 - Asbestos Mill Board Sheet
Material Description 

504 is a stiff & strong asbestos sheet manufactured by wet process using a blend of selected fibres & nitrile binders. This material is widely used for copper clad engine gasket, thermal shields & insulations of electrical devices & home appliances, various heat & acoustic insulation purposes where temperature does not exceed 500°C. This material is available in off-white shade.
