Leadsun Refractories manufactures a range of low cement and ultra-low cement castables that have an extended service life. Low cement and ultra-low cement castables are produced under the Leadsun brand name. Bulk density is high, porosity is low and they provide good thermal shock resistance. Leadsun castables exhibit excellent strengths at all temperatures, excellent abrasion resistance and high density with low shrinkage. These products can be vibration cast and/or free flow for installation. Excellent physical properties are obtained due to the installation techniques.

• High Alumina (45-95%) dense low cement castables are recommended for service temperature of 1400°C to 1800°C
• Compared to conventional castables, where strengths drop at intermediate temperatures, low cement castables exhibit increasing strengths with increase in temperature
• Exceptional strengths, high abrasion resistance and low level of impurities are its unique features

• Wide ranges of standard and customized products meet the requirement of various application areas
• Additionally, Silicon carbide based low cement castables are ideal for applications demanding high abrasion resistance and resistance to alkali coatings
• CUMIPLASCAST ranges of products are recommended for the roof linings due to their positive permanent linear change at high temperatures
