We have a true passion for lightweight solutions.
Sphere One’s lightweight Extendospheres® maintain low specific gravity without sacrificing strength. These low-density products allow the formulator to reduce their overall cost and the density of their finished goods.
Extendospheres® are compatible with most resin systems and provide benefits such as:
- Reduced product cost
- Lower density
- Improved material flow
- Reduced shrinkage & warpage
- Impact resistance
- Improved sound and thermal insulation
- Environmentally friendly
Solid Ceramic Spheres - Solospheres
Sphere One Solospheres are semi-solid ceramic microspheres. They are an excellent choice for applications requiring high strength, high temperature, and corrosion resistance. Solospheres spherical morphology are shear thinning in liquid applications allowing formulator to reduce the VOC’s and increase filler loading. Solospheres can easily disperse in a high intensity mixing or dispersion system in plastics. Their unique nature makes them suitable for some applications such as; Corrosion and abrasion resistance, flame retardant, coatings, refractory castings and coatings, self-leveling cements, and many more applications.
Synthetic hollow spheres are synthetically produced at our Chattanooga, TN facility by Sphere One, Inc. These spheres provide benefits of low density, good color, and closely controlled particle size distribution for formulators. The S series surface characteristics and shape are compatible with most resin systems. Elastomeric white roofing, cementitious coatings, castable resins, mastics, adhesives, and architectural moldings are a few examples of applications compatible for these grades. Synthetic Spheres are composed of 90% post industrial materials.
Extendospheres® HB-Series Hollow Spheres
Extendospheres® HB are white, low-density ceramic hollow spheres. With a density of 0.70 g/cm3 and a crush strength of 4,800 psi, these hollow spheres are ideal for use in coatings, sealants, caulks and other applications where low shrinkage, reduced weight and white or light colors are desired.
XOL Series Spheres
XOL products are white aluminosilicate multicellular hollow spheres. They significantly reduce composite density. XOL products are surface modified for better dispersion, bonding and strength. This product offers excellent economics compared to other additives.
