Microspheres description

Microspheres are made from alumina silicate and used as raw material in several manufacturing processes. They can improve the properties of the product in which they are applied and reduce the manufacturing costs of these.

Silica microspheres provide many advantages such as low cost of products by reducing the use of main materials to the benefit of using microspheres. They also favor a better handling during the production of the materials because they contribute to reducing their viscosity. In addition, the microspheres provide greater resistance to stress, greater strength and consistency and a reduction in weight in the final products. This lower weight due to the microspheres also positively affects a reduction in the cost of transporting the products.

The spherical, hollow and light shape of the microspheres also influences the improvement of their circulation and the reduction of breakage in mixing, pouring and falling of the products. As they are hollow ceramic microspheres, they provide, at the same time, a reduction in the density of the products and an ability to act as a thermal and acoustic insulator.

Applications

Glass microspheres can be applied in the following materials and situations:

Coatings and paints: Thermal insulating paints. Anti-condensation paints. Emulsifier in paint. Roof and wall coverings. Acrylic sealants.
Cultured marbles or synthetic marbles: Mix of calcium carbonate with resins. Weight reduction. Improved thermal cracking. Mortars.
Resins and molds: Non-reactive solvent for epoxy resins. Molds and dies.
Construction: Sandwich Panels. Fiber Reinforced Polymer (FRP). Concretes and cements. Refractory materials.
Nautical and aeronautical fabrications: Caulking and sealing. Fairing components. Gelcoat for finishes.
Explosives: Reduction of density and critical diameter. Increased detonation velocity and pressure.
Plasticizers: Tolerance to high temperatures. Improves electrical properties. Powdered polyester laminates. Polypropylene foam.
Synthetic woods: Improves finish appearance and resistance. Reduces price and weight per unit volume.
Adhesives: Weight reduction. Sound deadening. Protection against falls. Properties as an electrical and thermal insulator.
