Micro Glass Bubble for thermal reflective paint

Micro Glass Bubble for thermal reflective paint

Micro Glass Bubble for thermal reflective paint is a type of lightweight inorganic spherical powder filler. Composed of molten soda-lime borosilicate glass, they possess a closed, hollow structure with thin walls, uniform particle size, and excellent flowability, making them an ideal component for lightweight materials. Their low density, light weight, and hollow structure significantly reduce the density of composite materials, coatings, and adhesives, achieving efficient weight reduction and cost optimization. The product exhibits good chemical stability, is resistant to acids and alkalis, corrosion, and moisture, improving the weather resistance and service life of materials. Its smooth spherical structure provides excellent processing performance, improving system flowability and reducing viscosity and production energy consumption. It also possesses good thermal insulation, sound insulation, and electrical insulation properties, exhibits stable compressive strength, and is not easily broken under various processing conditions. As an environmentally friendly and highly efficient functional filler, it is widely used in plastics, composite materials, anti-corrosion coatings, thermal insulation materials, and polymer modification.

Features:

1. Hollow glass microspheres have a microscopic morphology of hollow spheres with a wall thickness of approximately 1-2 μm, exhibiting low density and high strength.
2. Low specific gravity and high floating rate, making them widely applicable as weight-reducing materials in rubber, latex, wood substitutes, PVC plastisol, and modified resin.
3. Produced using a special process, our products feature high crush strength and a high strength-to-weight ratio.
4. The hollow glass microspheres are made of soda-lime borosilicate glass with a softening point of approximately 600°C, allowing them to withstand temperatures below 600°C.
5. Low thermal conductivity and low dielectric constant. Glass bubbles are non-combusitable and nonporous, it creates a stable hollow structure when used in coatings or products, thus reducing thermal conductivity and dielectric constant.
6. Low Alkalinity, low volatile organic compound (VOC) content, and high viscosity.
7. Good flowability and low specific surface area.
8. Excellent electrical insulation properties and corrosion resistance.

As an additive in matrix materials, its main functions include:

1. Reducing weight.
2. Thermal insulation.
3. Sound insulation and noise reduction.
4. Improving dielectric properties.
5. Reducing resin usage and VOC emissions.
6. Increasing rigidity and preventing cracking.
7. Improving durability.
8. Improving volume stability and reducing shrinkage and cracking.
