RATH SG Products are versatile non-asbestos refractories reinforced with continuous ceramic fibers to increase the toughness, reliability and overall performance of the ceramic composite. SG-70 can withstand extreme thermal shock within specified temperature ranges

SG-70 and SGM-MU contain continuous fibers for "non-brittle behavior" and can withstand extreme thermal shock within specified temperature ranges. Chemically inert, these composites are durable and machinable.

SINDANYO® H-91 is an asbestos free cement board manufactured from alumina and Portland cements, high temperature fillers and binders and has the additional benefit of dispersible glass fibers as reinforcing agents. The material exhibits excellent strength even at high temperatures up to 700°C.

Marinite™ P is a structural insulation board formed from calcium silicate with inert fibers and reinforcing agents. Marinite P structural insulation is especially well suited to withstand both the temperatures and pressures associated with platen press operations.

These SG products are supplied in large sheets/boards and other engineered shapes. They are excellent material choices for structural insulating applications, and are natural replacements for asbestos-cement, silicate/mica/phosphate based materials and monolithic ceramics where superior performance is required.

SG-90A and SG-99A are high alumina sheets, which were developed for structural insulation and parting applications. Based on high purity and high alumina content these products are the ideal choice in vacuum furnaces and other special atmosphere heat treating units.

Advantages:

Non-brittle (SG 50, SG-70, SGM-MU)	Good reflectivity
Contain no asbestos	Good oxidation barrier
Low shrinkage	Good mechanical strength
High dielectric strength	Good electrical resistance
