Cenospheres: General Product Information
CenoStar 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 cenospheres have been developed for higher temperature applications such as refractory, high temperature coatings and flame-retardants.
We are pleased to offer four grades, as well as Custom Engineered Spheres -
We are pleased to offer four grades, as well as Custom Engineered Spheres.
EconoStar Series:
CenoStar’s standard grade has many uses, as it is the most versatile and lowest cost. The products in this series 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.
China White Series:
The China White Series spheres are a flagship product for CenoStar. The CW group is lower in density at 0.65 – 0.72 g/cc and has a near white color. CW spheres are available in 3 size ranges: <300 microns, <160 microns and <106 microns.
HAL Series:
The HAL Series spheres have high alumina content from unique sources of raw materials. They are especially suited to high temperature applications including refractory, foundry, coatings and flame-retardants.
High Grade Series:
The High Grade spheres are prized for their sphericity and cleanliness. Color is light tan.
Custom Engineered Spheres:
CenoStar prides itself in its ability to provide custom engineered spheres to meet your specific needs based on specific gravity, size distribution, color, chemistry, or a combination of these criteria. We can develop a product to meet your increasingly demanding applications.
EconoStar 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.
China White Series:
The CW spheres are a flagship product for CenoStar. The CW group is lower in density at 0.70 – 0.72 g/cc and has a lighter color, (Hunter scale 70-73). CW spheres are available in 3 size ranges: <300 microns, <160 microns and <106 microns.
HAL Series:
The HAL spheres are high alumina cenosphere. Unique sources of raw materials enable CenoStar to produce spheres with high alumina content (40-43%). It is especially suited to high temperature applications including refractory, foundry, coatings and flame-retardants.
High Grade Series:
The HG spheres are prized for their sphericity, cleanliness and contaminant free qualities. They have been floated, scrubbed and surfaced cleaned. Color is light tan (Hunter scale 74-78)
Custom Engineered Spheres:
CenoStar prides itself in the ability and willingness to custom design product to meet your specific needs.
Based on specific gravity, size distribution, color, chemistry, or a combination of these criteria, we can develop a product to meet your increasingly demanding applications.
