1100°C Calcium Silicate
Insulation Blocks

Produit Introduction

These 1100°C calcium silicate insulation blocks are specifically engineered for the cement industry, providing reliable thermal insulation for cement kilns, preheaters and other high-temperature cement processing equipment.

Based on xonotlite (6CaO·6SiO₂·H₂O), these blocks offer superior temperature resistance compared to ordinary calcium silicate materials, with a long-term service temperature of 1000°C.

The compact block format (standard size 300 × 150 × 50 mm) allows for easy installation and precise fitting in cement kiln linings and preheater systems.

Taille Standard: 300 × 150 × 50 mm (standard block size). Board sizes also available: 1230 × 500 mm, 1200 × 600 mm, 1080 × 950 mm, 1000 × 500 mm, 600 × 300 mm, thickness 25–125 mm (custom sizes available)

Product Characteristics

• ✓ Excellent thermal resistance — can bear continuous heating load jusqu'à 1000°C long-term, designed specifically for cement kiln environments.
• ✓ Low thermal conductivity — thermal conductivity formula: ≤0.058 + 0.00011t W/m·K, excellent insulation across all temperature ranges.
• ✓ Léger, résistance spécifique élevée — density 250–330 kg/m³, optimal weight for cement kiln insulation.
• ✓ Durabilité à long terme — no powder produced in the process of using, maintaining structural integrity over time.
• ✓ Non-toxic and safe — contains no asbestos, sulfur, chlorine or other harmful substances. A1 non-flammable grade.
• ✓ Moisture recoverable — absorbs water, but after drying the performance remains unchanged.
