Product Details

The boron-free glass fiber provides higher mechanical properties (modulus of elasticity) than E glass, superior chemical corrosion resistance, especially very similar acid resistance with traditional ECR glass. Without any content of B2O3 and F2, Boron-free glass is environmental-friendly throughout all its production process.  G1-AB is Boron-free roving designed for use in spray-up operations using standard or filled resin systems.  This includes applications in tub/showers, FRP building materials, heavy trucks and utility boxes.  Its excellent glass lay down makes it especially suitable for vertical surface spray-up. Roving doffs are square-edged, cylindrical packages which are firmly and evenly wound and have a constant traverse length. The packages are designed to provide a smooth run out, and their geometry is controlled to maintain the desired run out performance.
