S1-Glass Chopped Fibers

Style S1-Glass Chopped Fibers


S1-Glass Chopped fibers are designed for reinforcement applications.

With a tensile modulus of up to 87 GPa, S1-Glass represents one of the highest values in the Glass fiber family. This allows for larger panels at the same weight or reduced weight at same panel dimensions.
50% higher tensile strength than E-Glass yarns allow for higher loadings.

10 x higher fatigue properties increase reliability of the end product.
