TYPICAL USAGE for RR Fractalin(s):
Cer RR setter plates are excellent material to use as high temperature plates. Please contact MHI for custom shapes. Cer RR Fractalins have a high service life compared to any fiber insulating board, due to their mechanical, and chemical stability at high temperatures. Other applications include hot plates, setter plates, tops, gas combustion burners, fire protection and stops. Due to high porosity, high strength, and high melting point BR Fractalin boards find many other uses.
