PRODUCT INFORMATION 636 S-2 Glass® Yarn High-Strength Solutions for Your Toughest Reinforcement Challenges AGY’s S-2 Glass® high-strength fibers are specifically 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 difficult 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 filtration • Surfboards Aircraft Cargo Liner 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. Product Description 636 S-2 Glass direct sized yarns consist of numerous filaments of varying diamters, twisted to form yarns. The material’s starch-oil sizing, which protects the glass filaments from abrasion during processing, is typically removed after processing and the fabric is treated with a resin compatible finish. S-2 Glass Fiber Yarn S-2 Glass fiber offers significantly more strength than conventional glass fiber: 85% more tensile strength in resin impregnated strands Consistent high performance for reliable and durable finished parts Better fiber toughness, modulus of resilience and impact deformation than conventional glass fiber Improved impact capabilities to finished 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 fiber tensile strength and stability at elevated temperatures in thermoset and thermoplastic applications Enhanced stiffness Delivers 25% more linear-elastic stiffness than conventional glass fiber Excellent tolerance to damage accumulation The ability of composite parts to withstand high levels of tension and flexural fatigue without catastrophic failure Resin Compatibility • Starch-oil sized for weaving and processing S-2 Glass fibers deliver 20% reduction Radar transparency in dielectric constant over E-Glass fibers Long shelf life, good machinability and excellent durability Consistent performance and reliability Processes • Weaving • Braiding • Plying S-2 Glass fiber is an organic material Fire resistant
