Introduction
High Reflective Thermal Insulation Powder is an advanced functional filler made from alkali borosilicate glass. It is designed to provide excellent infrared reflectivity and low thermal conductivity, effectively reducing surface temperature and improving energy efficiency in coatings and construction applications.
Applications
Widely used in:
Metal roofs (color steel sheets, container houses, warehouses)
Exterior walls & concrete surfaces
Sunrooms & glass structures
Industrial and residential buildings

Key Features
1. Ultra-High Infrared Reflectivity：Reflects ≥98% of near-infrared radiation (590–2430 nm)
2. Cooling Effect：Reduces surface temperature by 17–29°C
3. Low Thermal Conductivity：As low as 0.06 W/m·K
4. Eco-Friendly Material：Non-toxic, VOC-free, suitable for green building applications
5. Excellent Durability：resistant to acid, alkali, weathering, and abrasion
6. Waterproof & UV Resistant：Enhances coating lifespan and outdoor performance
Working Principle
This material reflects near-infrared solar radiation (590–2430 nm) and forms a reflective layer within the coating system. It reduces heat absorption and lowers substrate temperature, achieving effective thermal insulation without additional energy consumption.
Compatible Systems
Suitable for incorporation into:
Water-based coatings
Solvent-based paints
Heat insulation coatings
Waterproof coatings
Topcoats & varnishes
Steel structure coatings
Advantages
1. Significant energy-saving performance
2. Easy to integrate into existing formulations
3. Improves coating functionality and value
4. Cost-effective thermal insulation solution
