S-GLASS FIBER YARN
High-strength glass fibers HS2, HS4 and HS6 are silicon-aluminum-magnesium system glass fibers that Sinoma tech developed to meet the needs of defense and military industry. They are called S-glass fiber.
Compared with alkali-free E glass fibers, the tensile strength of high-strength glass fibers increased by 30-40%, the elastic modulus increased by 16-20%, the heat resistance increased by 100-150°C, and the fatigue resistance of the reinforced material products increased by nearly 10 times. Moreover, the high-strength glass fibers have large fracture elongation, good impact resistance, good aging resistance, corrosion resistance, and resin impregnation performance.
