636 S-2 Glass® Yarn
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
636 S-2 Glass yarn is designed to be
used in transportation, construction
and recreation applications such as:
• Aircraft cargo liners
• High temperature insulation
• High temperature ltration
• Surfboards
Aircraft Cargo Liner

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, these yarns meet
the requirements of MIL-Y-114OH
specications.
Product Description
636 S-2 Glass direct sized yarns
consist of numerous laments of
varying diamters, twisted to form
yarns. The material’s starch-oil sizing,
which protects the glass laments
from abrasion during processing, is
typically removed after processing
and the fabric is treated with a resin
compatible nish.
