High Density Calcium silicate Board NR 85

Product Overview

Description

ASBESTOS FREE CALCIUM SILICATE INSULATION BOARD
Comparing with dense and lightweight refractory bricks or concrete, calcium silicate are the ideal rear lining construction material for all kind industrial furnace and kilns. As generally known, the low thermal shock resistance of calcium silicates excludes its use on the front side. Calcium silicate insulation materials can be produced as boards, pipe sections, segments and cut sections.

 

 

PROPERTIES & ADVANTAGES :
Low thermal conductivity
Low shrinkage
Low bulk density, lightweight
Good mechanical strength
Flexible size format, thickness up to 170 mm
Shaped parts available including pipe sections and segments
Good workability

 

 

APPLICATIONS :
Calcium Silicate materials are used in various industrial applications as thermal back-up insulation in a refractory lining.
Aluminium industry: anode baking furnace and electrolysis cells
Steel industry: smelting and heat treatment furnaces
Glass Industry: melting furnaces, heat treatment and forming furnaces
Ceramics industry: chamber and tunnel furnaces, kiln cars
Cement industry: heat exchangers and cyclone separators
Oil and Gas industry: fired heaters, process pipe insulation
Appliances: domestic fireplaces
