Electrical Properties

Due to its low alkali content, BOROFLOAT® 33 acts as a high-power insulator. BOROFLOAT® 33 is, therefore, a suitable material for applications where good non-conductive properties at temperatures (up to 450 °C) are called for. Because of the special structure of borosilicate glass BOROFLOAT® 33 has a neutron absorbing effect.
