Diatomite filler for thermal insulation materials is a lightweight inorganic material produced through low-temperature calcination and precision classification of natural diatomite. This specialized filler retains the natural microporous structure of diatomite, achieving exceptional porosity exceeding 85% and remarkably low thermal conductivity (0.05-0.08 W/(m·K)), which significantly enhances the insulation performance and durability of thermal materials.
As an eco-friendly insulation solution, this diatomite-based filler combines multiple advantageous properties including Class A1 fire resistance, excellent hydrophobicity, and complete non-toxicity. It is particularly suitable for building walls, pipeline insulation, and other construction applications, offering easy installation without generating dust pollution.
The incorporation of this filler enables a 20%-30% reduction in insulation layer thickness while lowering material costs by approximately 15%. These benefits contribute to more energy-efficient and low-carbon building solutions, supporting the development of sustainable construction materials that meet modern environmental standards without compromising performance.

What are the advantages of diatomite filler for thermal insulation materials? | |
Diatomite filler for thermal insulation materials is an environmentally friendly functional material produced through low-temperature activation of natural diatomite, offering outstanding core benefits. The material's ultra-high porosity (exceeding 85%) and exceptionally low thermal conductivity (0.05-0.08 W/(m·K)) significantly enhance insulation performance, enabling 20%-30% reduction in material thickness while maintaining equivalent thermal resistance, thereby decreasing building energy consumption. Its unique microporous structure provides Class A1 fire resistance without toxic fume emission when exposed to flames, coupled with excellent hydrophobic properties that effectively resist moisture damage and extend insulation system longevity. As an inorganic mineral-based material, this diatomite filler contains no harmful substances like formaldehyde or VOCs, complying with green building standards while demonstrating dust-free application and superior compatibility with cement, gypsum and other base materials. With its lightweight characteristics (bulk density ≤200 kg/m³), the filler reduces transportation and installation costs by approximately 15% while minimizing structural load requirements. By incorporating this diatomite insulation filler, manufacturers can simultaneously achieve energy efficiency, environmental safety, and cost-effectiveness - driving low-carbon sustainable development in the construction sector through this innovative material solution that combines performance with ecological responsibility. | |
