Superior Applications of Closed-Cell Perlite in Fire-Retardant Coatings

 Superior Applications of Closed-Cell Perlite in Fire-Retardant Coatings

Closed-cell perlite (Perlite Microspheres), as a lightweight inorganic filler, performs exceptionally well in the field of fire-retardant coatings:

Fire-retardant and flame-retardant – Refractoriness up to 1280-1360℃, effectively improving the fire resistance rating of coatings.

 Lightweight and heat-insulating – Density 100-300kg/m³, thermal conductivity only 0.028-0.040w/m·k

 Low water absorption – ≤0.5%, ensuring long-term coating stability.

 High strength – Compressive strength 200-2000Kpa, enhancing the mechanical properties of coatings.

Recommended model: Yanheal 550 – Optimized for architectural coatings, with uniform particle size distribution, excellent dispersibility and flowability, and good machine spraying effect.

Suitable for fire-retardant coatings for steel structures, intumescent fire-retardant coatings, fire-resistant putties, etc., helping customers reduce formulation costs while improving product performance.
