Low density cenosphere powder

SEPPE Cenosre is a lightweight, inert, hollow sre filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants. The color of cenosres varies from gray to almost white and their density is about 0.4-0.8 g/cm³, which gives them a great buoyancy. Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenosres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.

Cenosres are now used as fillers in cement to produce low-density concrete. Some manufacturers have begun filling metals and polymers with cenosres to make lightweight composite materials with higher strength than other types of foam materials. Such composite materials are called syntactic foam. Aluminum-based syntactic foams are finding applications in the automotive sector. Silver-coated cenosres are used in conductive coatings, tiles and fabrics. Another use is in conductive paints for antistatic coatings and electromagnetic shielding.
