Owens Corning launches new high-performance reinforcement for long-span pultrusion applications

News International-French

6 Apr 2011

At the JEC Composites Show, Owens Corning introduced XStrand® H roving, a new high-performance reinforcement solution for long-span composite parts manufactured using the pultrusion process.

The new high-performance XStrand® H roving is made with a proprietary boron-free glass formulation that meets R-Glass standards ISO 2078, ASTM C162 and DIN B1259-1 and performs better than conventional E-glass providing:

  • Up to 15 percent more stiffness
  • Up to 20 percent more strength
  • Up to 10 times more fatigue resistance at a given load
  • Resistance to strong acids equal to E-CR glass


"The new roving enables fabricators to create longer span, lighter weight components with lower deformation and superior strength," said High-Performance Reinforcements Program Leader in Europe, Eric Dallies. "XStrand® H roving was developed for demanding industrial applications such as ladder rails, lighting poles and telescopic rods."


XStrand® H roving provides significantly better fatigue resistance for longer useful life. Although specifically developed for use with polyester, vinyl ester and epoxy resin systems, it can also be used in acrylic and polyurethane systems to produce long span structural beams.
