CENOSPHERES: Lightweight, hollow ceramic microspheres, also known as glass bubbles, hollow microspheres, or hollow glass spheres.
They are natural and 100% recycled by-product of coal burning power plants.
Cenospheres - Recycled Aggregate
Cenospheres are created in the inferno of coal-fired power plants and have been used for more than 50 years to improve the qualities of many manufactured products. They replace mined minerals and resins, significantly lowering production costs.
Cenospheres - Functional Fillers
Cenostar spheres are used as functional fillers or extenders in plastics, low VOC filler for paints, composites, thermal coatings, epoxies, lightweight filler aggregate for cement, oil well drilling cements, ceramics and many construction products. They are superior hollow particle substrates for coated and surface modified particles, including Electro Magnetic Interference (EMI) shielding, silver and other metal surface coatings, coupling agents and electric conductivity.
Cenospheres - Free-flowing Alumina-silicate
Cenospheres are hard, inert, hollow, free-flowing alumina-silicate microspheres. Their uses are as diverse as reducing weight, friction and shrinkage, soundproofing, thermal insulation, lubricity, stealth applications, and coatings that create a 'torturous path' in many space vehicles. Cenospheres are comprised primarily of silica, iron and alumina with effective particle size distribution from 1 to 600 microns, and high strength of over 3000 psi.
