Duratec® 750/1000
Duratec is a machinable ceramic material made from calcium silicate, formed without the use of asbestos fibres.
It can be machined with great precision and is both thermally and electrically insulating up to 1000 deg C.
This material is porous and should be kept & machined dry.
DURATEC® 750
Improved product with higher strength, improved electrical
performance and arc resistance.
DURATEC® 1000
Machinable engineering material with good thermal stability
And electrical insulation properties.
