S Glass

S GLASSA family of magnesium-alumina-silicate glasses with a certified chemical composition which conforms to an applicable material specification and which produces high mechanical strength. Compared to E glass, S laminates show improved tensile strength, flexural strength, flexural modulus and compressive strength, impact resistance and toughness. S glass laminates are about 10% to 30% stronger than E-glass laminates, for the same weight.
