ZIRCAR Ceramics’ Alumina-Silica Type UNIFORM A is a unique family of ceramic-fiber-based insulation with exceptional machinability and very good strength in applications with temperatures to 1260°C (2300°F).
ZIRCAR Ceramics’ Alumina-Silica Type UNIFORM A is a unique family of ceramic-fiber-based insulation with exceptional machinability and very good strength. UNIFORM A products are made of specially prepared refractory ceramic fibers (RCF) with inorganic amorphous silica as a binder. This binder is uniformly distributed throughout the thickness of the body without the use of any organic binders and therefore UNIFORM A produces no smoke or odor when heated. Uniform products are designed to deliver low thermal conductivity with excellent thermal shock resistance.
UNIFORM A is manufactured in two varieties:
UNIFORM A1, with a bulk density of 0.29 g/cc (18 pcf) and
UNIFORM A2, with a bulk density of 0.45 g/cc (28 pcf).
UNIFORM A exhibits excellent resistance to chemical attack and is not affected by oil or water. It is, however, affected by hydrofluoric acid, phosphoric acid and strong alkalis.
