Company record

Rath Incorporated manufactures insulation and refractory materials, offering a portfolio that centers on high‑purity alumina fibers—including alumino‑silicate, mullite, and variants described as high, dense, and bubble alumina. These fibers are supplied in multiple formats such as ceramic‑fiber bulk, blankets, boards, and custom‑shaped forms. In addition to stock products, Rath Incorporated designs and produces tailored insulating systems for both end‑users and original‑equipment‑manufacturer furnace builders, covering service temperatures from 1,000 °F up to 3,272 °F. The company also provides a suite of insulating services that encompass engineering, installation and repair, fabrication and assembly, die stamping, and custom machining. Typical applications for Rath’s solutions include insulation linings for crystal‑growing equipment and specialty glass processes, microwave heating and drying systems, semiconductor and thermal‑analytical instruments, as well as powdered‑metallurgy operations.
