Mantec manufactures its Ultralite Refractory Castables by blending its highly successful Ultralite Loose Fill (ULF) insulation material with high grade refractory aggregates and cements, which results in a range of ultra-lightweight monolithic refractories with exceptional heat insulating properties and very low densities.

Mantec’s flexible monolithic refractories can be used in a variety of applications, such as a hot face or back-up refractory kiln lining, in the sub-floor of a kiln or kiln car base and the creation of lightweight monolithic cast shapes and are excellent alternatives to more traditional monolithic refractories or ceramic fibre products.

The range of Ultralite Refractory Castables has maximum service temperatures ranging from 950°C (1742°F) up to 1300°C (2372°F) and densities from 325kg/m³ (20.28lb/ft³) to 645kg/m³ (40.27lb/ft³):

Ultralite Refractory Castables versus Conventional Castables

Ultralite Refractory Castables are superior replacements to more traditional refractory castables and therefore offer a real alternative choice for the discerning manufacturer.
