Single-End Roving

PulStrand® PRO41 Roving


Make More With Less

PulStrand® PRO41 Roving is designed to maximize pultrusion processes by reducing the number of glass doffs needed. High tex reduces floor space, improves downtime and labor, and provides the opportunity to make larger parts without compromising mechanical properties/processing.


Performance Attributes

  • Reduced Cost

    75% less floor space required to run your product line. <br> Product change overs require fewer doffs and less labor. <br> Space savings and large tex enables you to make larger parts with the same set-up.

  • Efficient Processing

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

  • Impressive Mechanical Properties

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

Rovings are available in a single-end internal- pull package. Each pallet weighs about 1 ton and can be packaged in bulk or Creel-Pak(TM) packaging format. Pallets are stretch-wrapped for load stability and for protection during transport. All individual packages are wrapped with Tack-Pak(TM) 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.
