  • Suitable for polyester, vinyl ester, epoxy, and polyurethane resin systems
  • Very good resin-to-glass adhesion and fast wet-out
  • Improved flexural, shear, and compressive strength of composite products

Owens Corning launched a new range of multi-compatible single-end roving in the North American Market. The PulStrand 4100 roving offers processing and performance advantages in pultrusion compared to other existing materials in the market.

Suitable for polyester, vinyl ester, epoxy, and polyurethane resin systems

The global composites market for pultrusion continues to grow requiring higher performing solutions. The PulStrand 4100 product offers superior processing qualities, strength, and fatigue resistance in a multi-compatible product for polyester, vinyl ester, epoxy, and polyurethane resin systems. This higher-productivity material has the potential to provide faster line speeds while reducing downtime, scrap, and labor, and enhances the modulus and durability of the pultruded profiles.

Very good resin-to-glass adhesion and fast wet-out

The sizing chemistry of the PulStrand 4100 product ensures very good resin-to-glass adhesion and fast, uniform wet-out by more than 50 percent when compared to existing products1. Further extensive benchmark tests of competitive products have also shown a reduction of fuzz formation of up to 92 percent2, less part bowing, and deformation and very good humidity resistance.

Improved flexural, shear, and compressive strength of composite products

In addition, the sizing also allows for increased glass content (higher modulus) and helps to improve the flexural, shear, and compressive strength of composite products. Tests have highlighted an increase of up to 57 percent3 in flexural strength. Combining these characteristics with the very good corrosion resistance provided by Advantex E-CR glass, the PulStrand 4100 product is specially designed for applications in corrosive environments.
