Multi-Compatible PulStrand™ Single-End Roving from Owens Corning provides Game-Changing Processing Performance in Pultruded Applications

Tuesday, March 10, 2015 12:00 am EDT
"Our new PulStrand™ 4100 product has the potential to help improve the profitability of our customers and represents a more durable, stronger product for demanding markets"

Owens Corning (NYSE: OC), a leading global producer of glass fiber reinforcements and engineered materials for composite systems, today announced the launch of its innovative PulStrand™ 4100 roving at the JEC Europe 2015 show and conferences. 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 and more competitive solutions. The new 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 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 new PulStrand™ 4100 product has the potential to help improve the profitability of our customers and represents a more durable, stronger product for demanding markets,” said Bryan Minges, 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.

Owens Corning is exhibiting at JEC Europe 2015 in Hall 7-2, Booth F22.
