TOP SEALING CERAMIC FIBER BLANKET Made from bulk fibres produced by the most modern spinning process, giving exceptional length and uniform distribution which are ideal for manufacturing blanket of controlled density, high tensile strength and resiliency. They have superior acoustic as well as thermal insulation characteristics. It is ideal for furnace, boiler duct and stack lining due to its low-thermal conductivity and low-heat storage allowing shorter cycle times and quicker access for maintenance.
