Product Description
933 S-2 Glass yarn is designed to be used in aerospace, defense and recreation applications such as:
  • Radomes
  • Leading and trailing edges of aircraft wings

Product Solutions
S-2 Glass fibers offer a unique combination of properties: strength, impact resistance, stiffness, radar transparency and temperature and fatigue resistance. Compared with other reinforcing materials, S-2 Glass fibers weigh less than conventional glass fiber and deliver better cost performance than aramid and carbon fibers. In addition, these yarns meet the requirements of MIL-Y-114OH specifications.

933 S-2 Glass direct sized yarns consist of numerous G-filament (9 microns) continuous glass strands, twisted to form yarns and treated with a thermally stable inorganic sizing for high temperature matrices.
