Insulating Brick
Chinese Refractory raw material resources are abundant, which are suitable for the production of various grades of insulating firebrick. Limiting temperature of use range from 900º C to 1650º C. Each grade of insulating firebrick is formulated to meet specific thermal and physical requirements. Top grade insulating firebrick are made 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 controlled, uniform lacuna structure. Each brick machined to precise size on all six faces. The maximum continue use temperature depends on application. If you have any question, please feel free to contact us.
