Masonry brick JM®

furnaceinsulatingrefractory

The JM Insulating Firebrick (IFB) series are industry leaders in applications such as Petrochemicals, Metals, Ceramics, and Glass, where the ability to operate in environments with a classification temperature up to 1650°C (3000°F) is critical. JM IFB series are manufactured from high-purity refractory clays, with graduated additions of alumina for the higher temperature products and a carefully graded organic filler, which burns out during manufacture to give a uniform, controlled pore structure. Each grade is formulated to meet specific thermal and physical requirements and are machined to precise tolerances on all six faces. Our IFB range - JM, K, and TJM - delivers big energy savings for many markets, and our global manufacturing footprint enables Morgan to meet your regional and global application demands. A comprehensive range of mortars are also available to suit the different grades of brick.
