FiberForm® Insulation
FiberForm is a low density, rigid, carbon fiber insulation material designed to perform at high temperatures in vacuum and inert furnaces. FiberForm can be supplied with a variety of coatings from TC-2™ graphite reflective paint for applications requiring a greater resistance to physical or chemical attack. Horizontal fiber orientation of this FiberForm insulation results in excellent through-the-thickness thermal insulation properties. Additionally, this high quality product has an increased resistance to chemical deterioration and moisture absorbance. FiberForm is available in large size boards, cylinders and discs.

FiberForm board stock can be machined to produce complex configurations:
- Cylindrical configurations
- Spill trays for crystal growing furnaces
- Discs (lids) for vacuum or inert gas furnaces
Applications include thermal insulation for vacuum or inert atmosphere furnaces utilized in heat treating metals, ceramics and carbides along with crystal growing applications for the semiconductor industry, as well as CVD furnaces utilized in carbon brake manufacturing.
