Cenospheres are used to reduce the weight and increase the strength of concrete, resins, plastics, ceramics, paints, coatings and many other building products, including house panels and siding as shown in the bottom left photo. bottom. 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 light-weighting agent. Also improves mechanical properties such as comprehensive, tensile and flexural strengths and well as 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.
