Cenospheres are used to reduce weight and increase the strength of concrete, resins, plastics, ceramics, paints, coatings and many other products including house panels & siding (as shown). Other benefits include: increased filler loading, lower porosity and viscosity, reduced shrinkage, fireproofing, thermal insulation and lubricity.
CenoStar’s standard grade ES Series has many uses. It is the most versatile and lowest cost cenosphere. Depending on customer requirements we have (4) grades ranging in size. The color is light to medium shades of grey.
High Alumina (HAL Series)
These cenospheres have a high Alumina content (32-40%). It is especially suited to high temperature applications including refractory, foundry, coatings & flame retardants.
LightStar (LS Series)
This is the whitest and strongest cenosphere available. It is useful as a color and/or weight lightening agent when combined with cements and building products. Improves compressive, tensile, and flexural strength.
Custom Engineered Spheres
We will custom design and develop product to meet your specific needs applications based on: specific particle distribution, color, density, and other performance characteristics.
