Materials for Demanding Environments


RF materials for extreme environments.

ATC develops materials for dielectric performance in demanding environments, including hypersonics. Materials are moldable to improve manufacturability of complex geometries and designed for stable, repeatable dielectric performance over a wide temperature range.

RIPS (Reduced-density Injection-moldable Pressureless-sintered Silicon-nitride)

  • Moldable to net shape
  • Low dielectric <5.0
  • Consistent, stable performance to elevated temperatures
  • Continuous use to 1400°C+

RIPS was created for low dielectric performance in extreme environments. RIPS's patented formulation and production process allow for net-shape molding of accurate components and complex geometries. RIPS has been evaluated for use in hypersonic applications by Air Force, Army, Navy, and DoD partners.

Hotblox Composite Dielectric

  • Moldable to net shape
  • Dielectric grades from 1.5 - 3.0
  • CTE matched to aluminum
  • Continuous use to 350°C

Hotblox provides customized dielectric performance for harsh environments to 350°C. Moldable to net shape, Hotblox enables economic production of complex geometries for antennas, waveguides, RF components, and other applications. With a CTE matched to aluminum Hotblox components may be molded-in-place within aluminum housings and will maintain an interference fit throughout temperature cycles.
