DURATEC 750
DURATEC
750 is machinable
insulating ceramic material with a calcium silicate composition. It is
suited to electrical insulation applications requiring high temperatures
DURATEC materials are asbestos free.
Properties of DURATEC 750
DURATEC
750 is useful where
a high temperature, thermally insulating component is required. It also
has good electrical insulation and arc resistance.
