Duratec

Duratec

Duratec is a high-density versatile engineering material in Calcium silicate.

It is non-combustible and operates in electrical & thermal environments up to 1000°C. Available in 2 grades:

Duratec 1000 exhibits low shrinkage
Duratec 750 exhibits higher strength

The strength of Duratec is substantially maintained at maximum temperature, Duratec 750 actually increasing in strength at elevated temperatures.
