- Extreme Heat Resistance
With a melting point around 1300°C, 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.
