Cenospheres: are inert, hollow ceramic spheres. They are used to reduce weight in concrete, resins, plastics, ceramics, paints, coatings and many other building products. Other benefits include increased filler loading, reduced shrinkage, lower viscosity, fireproofing, lubricity, and transportation cost savings

High Alumina Series

Cenospheres have been developed for higher temperature applications such as refractory, foundries and high temperature coatings and flame-retardants. The low particle density of Cenospheres enables slower stages of separation in paints and adhesives unlike using heavy metallic and inorganic fillers.

Light Star Series

Multiple varieties of near-white Cenospheres are each from specific sources - we guarantee consistency, and the Light Star Series averages 60% the cost of Aussie whites without sacrificing consistency, availability or value.

The LS160 Grade and LS300 Grade Cenospheres are low density, fine particle size, hollow ceramic spheres. Typically used to reduce density, reduce VOC levels, increase filler loadings, and improve viscosity in a variety of formulations. Useful as a lightening agent when combined with cements That improve the mechanical properties, including compressive strength, tensile strength, flexural strength and fracture toughness

Econo Star Series

CenoStar’s standard grade ES series has many uses as it is the most versatile and lowest cost amongst the various grades. The four products range in size from <600 microns, <300 microns, <160 microns and <106 microns with specific gravity ranging from 0.65g/cc to 0.9g/cc depending on customer requirements.
