Performance Attributes

  • Outstanding Mechanical Properties

    Excellent shear and flexural properties in major resin systems, provide maximum part strength and long part service life.

  • Reduced Cost

    Fast, uniform strand wet-out leads to higher glass loading, reducing resin demand; fast wet-out also increases production speed and productivity resulting in reduced manufacturing cost.

  • Multi Resin Compatibility

    Excellent glass/resin bonding in polyester, vinyl ester, polyurethane, acrylic, and epoxy resins, providing the processor maximum flexibility with one input glass. This reduces cost with less inventory to carry and eliminates the need for costly downtime and labor to change input glass during job changes. Suitable for LFTP PA compounding applications

  • Excellent Processing

    Smooth run-out combined with low fuzz properties, result in smoother parts and less downtime for clean-up, enabling higher efficiencies and lower manufacturing costs.

  • Corrosion Resistant

    Excellent corrosion resistance with Advantex® Glass compared to standard E-glass: providing longer service life in applications facing corrosion.

Rovings are available in a single-end internal- pull package. Each pallet weighs about 1 ton and can be packaged in bulk or Creel-PakTM packaging format. Pallets are stretch-wrapped for load stability and for protection during transport. All individual packages are wrapped with Tack-PakTM packaging to aid package run- out and transfer. More information is available in the Customer Acceptance Standards.


Each individual package is labeled with information including: product name, tex/yield, producing plant, and production date.


Glass fiber products should be stored in a cool, dry area. The glass fiber products must remain in their original packaging material until use; the product should be stored in the workshop, within its original packaging, 48 hours prior to its utilization, to allow it to reach the workshop temperature condition and prevent condensation, especially during cold weather. The packaging is not waterproof. Be sure to protect the product from the weather and other sources of water. When stored properly, the product has no known shelf-life issues, but retesting is advised after three years from the initial production date to insure optimum performance.

Regional Availability

PulStrand 4100 is available in North America, Europe and Asia Pacific.
