Refratechnik hybrid castables | Also suited for low temperatures

Refratechnik hybrid castables:

Also suited for low temperatures.

The technology of cement-free Sol-Gel-bonded refractory castables makes another step forwards. Our new hybrid castables permit fast heating combined with high strength – also at low temperatures.
This offers advantages in the production of prefabricated components or the lining of e.g. fluidized bed furnaces and refuse incineration plants.

Strengths of REFRACAST® Hybrid F-60 AR/R compared with a conventional Sol-Gel-bonded refractory castable: Clear advantages for hybrid

REFRACAST® Hybrid F-60 AR/R Comparable Sol-Gel-version

Advantages of hybrid castables

compared to conventional cementitious materials:

Faster heating up with shorter downtimes
Cost and energy-saving
Very good adherence on existing refractory materials
Installation possible on hot surfaces and with high ambient temperatures
Higher application temperature limits
Optimized thermomechanical behaviour
Long storage life of 12 months
Increased cold crushing strength and modulus of rupture as well as optimized abrasion resistance in the temperature range below 1000 °C.

Cold crushing strength of hybrid castables and conventional Sol-Gel-bonded castables at 20 °C / 24 h: Hybrid castables exhibit a significant increase in cold crushing strength
