3R 4300
CERAMIC BOARD

ISO 9001 : 2000 Certified

The refractory vacuum formed boards are a rigid self-supporting fiber insulation from a slurry consisting ceramic fibers and binders. They offer low thermal conductivity, excellent strength and thermal stability at elevated temperatures. M Board products have the capability to withstand chemical attack. Exceptions include hydrofluoric acid, phosphoric acid, and strong alkalis.

The 3R 4300 is a low cost high strength product recommended for tough mechanical stress areas. Also, very good for back-up behind dense refractories.

Applications //

Appliance and heat processing insulation, back up in steel ladle and torpedo cars, back up insulation to dense refractories, combustion chamber construction, expansion joint material, flue and chimney linings, furnace, kiln and oven hot face linings; general molten metal contact, glass coffin walls, glass regenerator insulation, glass tank side, end wall and port neck, glass tank wall and port neck insulation, heat shields, High temperature gaskets and seals, high mechanical stress areas, kiln furniture and trough linings in contact with aluminum.

Physical properties//


Color	Beige
Nominal density, pcf (kg/m³)	26 (416)
Maximum temperature rating	2 400°F (1316°C)
Continuous use limit	2 300°F (1260°C)
Melting point	3 200°F (1760°C)
Modulus of rupture, psi (Mpa)	150 – 175 (1.03 – 1.20)
Compressive strength, psi (Mpa) @ 5% def. @ 10% def.	50 – 70 (0.34 – 0.48) 70 – 90 (0.48 – 0.62)

A small amount of combustible organic binder will burn out at approximately 300°F. Caution should be exercised during the initial heating. Adequate ventilation should be provided to avoid potential flash ignition of the binder out-gassing and to avoid air entry while at elevated temperature.
