Calcium Silicate Blocks – Rigid High-Performance Insulation by Mitticool Refractories
Overview
Mitticool Refractories offers durable and efficient Calcium Silicate Blocks designed for high-temperature insulation and structural strength.
Manufactured using high-grade lime and silica, these blocks provide excellent thermal insulation, low thermal conductivity, and superior mechanical strength even under continuous high-temperature conditions.
Our Calcium Silicate Insulation Blocks are ideal for industrial furnaces, boilers, kilns, and other thermal processing equipment where stable, lightweight insulation is required.
Product Description
Calcium Silicate Block is a rigid, high-strength insulation material made by mixing fine silica, lime, and reinforcing fibers under controlled conditions.
It offers excellent dimensional stability, low shrinkage, and outstanding heat resistance, making it a preferred choice for back-up insulation in refractory linings and process equipment.
These blocks are non-combustible, asbestos-free, and easy to handle, cut, or machine — making installation simple and efficient.
