Material & Typical Use
Composition and application overview
Direct answer: KXB400 is made of asbestos fibre, rubber and heat-resisting packing material compressed into thick paper form, and is used for equipment in water and steam, plus sealing material in the joints of pipelines.
Composition
Asbestos Fibre + Rubber + Heat-Resisting Filler
Long asbestos fibre is compounded with rubber and heat-resisting packing material, then compressed into a dense jointing sheet with consistent thickness and density.
Service Media
Water, Steam & Similar Media
Mainly used as sealing material for pipeline joints and equipment handling water, steam and other similar industrial media. For oil and fuel service, please refer to the oil-resistant KNY series.
02
Position in the KXB Series
Tensile strength ladder from KXB150 to KXB510
Direct answer: Kaxite manufactures eight compressed asbestos rubber sheet grades. Tensile strength rises from 5.0 MPa for KXB150 up to 21.0 MPa for KXB510, and KXB400 sits in the higher-strength section at 15.0 MPa.
