Syntactic foams are complex compounds produced by the incorporation of hollow spherical particles into a polymeric or ceramic matrix. The American Society for Testing and Materials (ASTM) states that synthetic foams have a resin matrix. The properties of synthetic foam can be largely determined by changing some parameters during their production such as the material […]

Sound insulation properties of Hollow Ceramic Cenospheres
Fig. SEM micrograph of broken cenosphere showing its hollow characteristics and porous walls. Noise is becoming an increasingly significant concern because of its adverse effects on the lives many people in urban societies and in rural areas. Noise arising from different sources such as vehicles, aircrafts, power plants and machinery is not only uncomfortable but […]
Expanded Glass ‘’Stiklo”
The foamy particle with thermal and sound insulation properties. ‘’Stiklo” granular glass is an innovative, ecologically valuable material from recycled glass. This organic spheroid porous composition is produced when the recycled glass is ground, mixed with impregnating agents and melted at an extremely high temperature. Expanded glass features: Low coefficient of thermal conductivity. Fire resistance. […]
The “miraculous” Hollow Microspheres – Bubbles!
General description The Hollow Microspheres are inert, hollow particles made mainly of silicon, alumina and boron-silicate soda lime, which inside their core contain inert gas (e.g. nitrogen) or carbon dioxide. They are the ideal lightweight fillers as they provide the lowest surface-to-volume ratio of any size. This fact results in the need for less resin […]
Special paints and coatings
Condensation and Related Issues There is always some moisture in the air, even if it is not readily visible. If air gets cold, it cannot hold all the moisture produced by everyday activities and some of this moisture appears as tiny droplets of water. This is readily noticeable on windows on a cold morning. This […]
Cool roof coatings
Introduction The expanding residential building market has placed a higher demand on electricity for cooling in warmer climate regions. This demand has created opportunities for coatings companies to investigate solar heat reflective coatings as a means to combat the increasing energy costs. Two popular areas being investigated in the architectural arena are roof and wall […]
