933 S-2 Glass® Roving
High-Strength Solutions for Your Toughest
Reinforcement Challenges

AGY’s S-2 Glass® high-strength bers
are specically designed to meet your
most demanding performance
processing and cost requirements.
AGY’s global network of people and
facilities are ready to help you develop
innovative solutions to your most
difcult reinforcement challenges.
Product Application
933 S-2 Glass roving is designed to be
used in aerospace, defense, and
recreation applications such as:
• Aircraft Flooring
• Helicopter Blades
• Radomes
• Composite Structures
Product Solutions
S-2 Glass bers 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
bers weigh less than conventional
glass ber and deliver better cost
performance than aramid and carbon
bers. In addition, they meet the
requirements of MIL-R-60346 Type IV
Class 1 specications.
Product Description
933 S-2 Glass roving consists of
numerous G lament (9 microns)
continuous glass strands, gathered
without mechanical twist and treated
with a thermally stable inorganic
sizing for high temperature matrices.
