Product Description

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 of 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 ,100-150ºC higher temperature endurance, also they have excellent impact resistance because of high elongation to break, high ageing & corrosion resistance and quick resin wet-out properties. 

HS4 glass has reached the standard of S-2 & R glass.
