Cenospheres - clean and graded in bulk

Cenospheres - clean and graded

Ceno Technologies supply clean and graded cenospheres which have unusually high compressive strength and can easily handle pressures of 4,000 psi without breakage. This immense strength extends their versatility by providing increased breakage resistance during mixing, processing and application. Their light gray color consistency will always give you the results you expect, as well as delivering lower tint costs.

Extreme Heat Resistance: With a melting point around 1300° Celsius, clean and graded cenospheres from Ceno Technologies can withstand temperatures far higher than any comparable thin-walled hollow glass microsphere. This extreme temperature resilience is achieved through unique refractory properties.

In addition to these unique features, Ceno Technologies clean and graded cenospheres provide all the benefits you would expect from a microsphere and can improve the properties and performance of many formulated products.
