762 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
762 S-2 Glass yarn is designed to be
used for producing reinforcing cords
for rubber belts and sheets in
applications such as:
• Synchronous timing belts
• Manufactured rubber goods
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
762 S-2 Glass yarn consists of
numerous E or G-lament (7 or 9
micron) continuous glass strands,
untwisted and treated with a sizing
compatible with various rubbers.
Resin Compatibility
• Chloroprene
• Resourcing-Formaldehyde-Latex
(RFL) Rubber
Processes
• Cording • Braiding

Features

Benets

S-2 Glass ber offers signicantly
more strength than conventional glass
ber: 85% more tensile strength in
resin impregnated strands

Longer life or narrower belt, saving
space in engine compartments

Better ber toughness, modulus of
resilience and impact deformation
than conventional glass ber

Improved impact capabilities to
nished parts and higher
composites durability and
damaged tolerance

Softening point: 1056°C (1932°F)
Annealing point: 816°C (1500°F)
Strain point: 766°C (1410°F)

Greater ber tensile strength and
stability at elevated temperatures
in thermoset and thermoplastic
applications

Enhanced stiffness

Delivers 25% more linear-elastic
stiffness than conventional E-Glass
or standard aramid bers

Excellent tolerance to damage
accumulation, high strain to failure,
outstanding fatigue life

The ability of composite parts to
withstand high levels of tension
and exural fatigue. Timing belt
life in range 150,000-240,000km

Coefcient of thermal expansion about
70% lower than conventional E-Glass

Consistent performance and
tension over a wide temperature
range reducing dependence on
complex and expensive autotensioning devices
