It is high strength glass fibers made from magnesium alumina silicate system which meets the needs of military and other applications where high strength and high performance is required.
S-glass is generally used for polymer matrix composites that require improved mechanical properties compared to E-glass based composites. This is often the case when the bmaterial is operated under more extreme conditions.
S-glass will has the same working qualities as a standard E-glass, however you will gain an approximate 25-30% increase in breaking strength. Used in applixations where the most possible strength is required while keeping weight to a minimum.
Product Feature:   
1. 30-40% better tensile strength.
2. 16 to20%higher modulus of elasticity.
3. 100 to 150 degrees Celsius better temperature endurance
4. 10 fold higher fatigue resistance  
5. Excellent impact resistance because of the high elongation to breakage.
6. High ageing and corrosion resistance.
7. Quick resin wet-out properties.
8. Weight saving at the same performance.
