Phenolic resin for refractory

Introduction:

Phenolic resins for refractory include thermosetting liquid resin and thermoplastic liquid/ powdery resin. Basing on the various properties for alumina-carbon and magnesia-carbon materials, we develop a series of resin with high wettability for high plasticity mortar. The refractory with this series in has high strength and uniform matrix, and can meet customers’ requirements for mixing and moulding. The powdery resin for dry ramming mix has low smoke emission, good bonding property and good stability

Application:

Thermosetting liquid series is used in MgO-C bricks, MgO-Al2O3--C bricks, Al2O3-SiC-C bricks, slide gates & nozzles, RH bricks and three large parts. Thermoplastic liquid series is used in MgO-C bricks and slide gates. Thermoplastic powdery series is used in MgO-C bricks, slide gates and dry ramming mix.
