By Business Wire News


Owens Corning (NYSE: OC), a leading global producer of glass fiber reinforcements and engineered materials for composite systems, today announced the North American launch of its innovative PulStrand™ 4100 roving at the CAMX 2015 show. The PulStrand™ 4100 roving delivers breakthrough processing advantages and performance benefits in pultrusion compared to existing competitive offerings.

The global composites market for pultrusion continues to grow requiring higher performing solutions. The PulStrand™ 4100 product, introduced in Europe in early 2015, 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 for a variety of high-performance markets.

The sizing chemistry of the PulStrand™ 4100 product ensures excellent 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 excellent humidity resistance.

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 outstanding corrosion resistance provided by Advantex® E-CR glass, the PulStrand™ 4100 product is specially designed to optimize the durability and service life of applications in corrosive environments.

“Our global customers are seeing the potential of PulStrand™ 4100 to help improve their performance and productivity. We’re very pleased to be introducing this product to the North American market,” said Mikhail Vorobiev, Global Product Manager at Owens Corning.

The PulStrand™ 4100 product covers a wide tex range (600-9600) and can be customized to specific application requirements allowing for the production of profiles for the consumer, recreation, corrosion, electrical, transportation, and construction markets.
