Sell High Strength Fiberglass

HS2 & HS4 high strength glass fibers made from the magnesium alumina silicate glass system meeting the needs of military application have been developed and put into volume production Since 70’s & 90’s last century respectively. 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,also they have excellent impact resistance because of high elongation to break, high ageing & corrosion resistance, quick resin wet-out properties. HS4 glass has reached the standard of S-2 & R glass.
