S glass woven fiber is known as its high strength,modulus. S-Glass has a typical nominal composition of SiO2, Al2O3 , MgO content. Compared with E glass fiber, they exhibit 30-40% higher tensile strength,16-20% higher modulus of elasticity , 10 folds higher fatigue resistance ,100-150 oC higher temperature endure. Taking advantage of its properties, S glass fiber products are used for high strength need or belletproof required.
