~High Tensile Strength Fiberglass Roving (S-glass)

High Tensile Strength Fiberglass Roving (S-glass) 2nd (HS2), High Tensile Strength Fiberglass Roving (S-glass) 4th (HS4), High Tensile Strength Fiberglass Roving (S-glass) 6th (HS6) is our company since the 1970s were a period of adaptation needs of defense industry developed and put into production scale industrial production of magnesium-alumina-silicate glass system, for which abroad named S or R fiberglass.

Compared with E-glass roving, they have 30-40% higher tensile strength, 15-20% higher modulus of elasticity under condition of 4020, 4600MPa, 100-150degree higher temperature endurance under condition of 82.9, 86.4GPa, 10 times higher fatigue resistance,also they have excellent impact resistance because of high elongation to break, high ageing&corrosion resistance:quick resin wet-out properties.
