Insulating Castable

Insulating Castable, also called Lightweight Insulating Castable, is mainly used for linings of heating equipment such as heat insulating layer in high temperature industrial stoves. These materials have advantages of medium lightweight and good thermal insulation property. Its excellent features of good mixability, strong adhesive property, long initial setting time and operable time in construction, fast increasing of strength, strong anti-permeability, no need for acidizing and easy for the mortar joint dense of brickwork can remarkable improve the air impermeability, integrality and lining corrosion resistance of chimney lining, which is the ideal cementing material of chimney stack, high temperature flue and air flue lining.

Description for Insulating Castable for sales

1) Insulating Castable Refractory is mainly classified according to apparent porosity, binding agent and aggregate variety, and also according to operating temperature or functional characteristics in the actual use.
2) Insulating Castable can be classified into Dense Refractory Castables and Insulating Castable with higher than 45% apparent porosity.
3) Insulating Castable can be classified into hydrsulic bond, chemical bonding and coagulating binding castable according to binding agent.
4) Insulating Castable Refractory can be classified into argillaceous aggregate, high alumina aggregate, silicious aggregate, alkaline aggregate (magnesia, dolomite), special aggregate (carbon, carbide, spinel, zirconite, nitrides) and thermal insulation aggregate (perlite, vermiculite, ceramsite, floating bead, lightweight brick sand, porosity clinker and alumina hollow ball).
