PRODUCT INFORMATION 493 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 493 S-2 Glass yarn is designed to be used for producing composite hybrids and structural laminates in the woven and braided markets. Common applications include: • Wire insulation • High performance sails • Snowboards and skis 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 493 S-2 Glass direct sized yarns consist of numerous G-lament (9 micron) continuous glass strands, twisted and treated with a sizing compatible with epoxies or polyesters. Resin Compatibility • Epoxy • Polyester Processes • Weaving K-2 Skiis S-2 Glass Fiber Yarn S-2 Glass ber offers signicantly more strength than conventional glass ber: 85% more tensile strength in resin impregnated strands Consistent high performance for reliable and durable nished parts 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 glass ber Excellent tolerance to damage accumulation The ability of composite parts to withstand high levels of tension and exural fatigue without catastrophic failure S-2 Glass bers deliver 20% reduction Radar transparency in dielectric constant over E-Glass bers Long shelf life, good machinability and excellent durability Consistent performance and reliability
