High Density Calcium Silicate
Isolation Thermique 800 kg/m³

Produit Introduction

The main high-density calcium silicate materials on the market are made of xonotlite with molecular structure CaO·SiO₂·5H₂O. Our factory uses a Dynamic Method to produce thin-fiber xonotlite with the structure CaO·SiO₂·H₂O.

The newly invented material has lower thermal conductivity, higher service temperature, and is durable for a longer service life compared to conventional high-density calcium silicate products.

Widely used in different industries, formed into various shapes as machine parts or moulds for demanding high-temperature applications.

Taille Standard: 1230 × 1230 mm thickness  6-160mm; 1250 × 2500 mm thickness 10-80mm; 1200 × 600 mm thickness 10–160 mm (custom sizes and shaped products available)
