Type 30® Single-End Roving


High Strength, Minimized Costs

158B Roving is specifically designed for use in filament winding applications using epoxy resin, where high strength is required. 158B is suitable to reinforce phenolic resins. Fast wet-out properties and high burst strength maximize customers’ processing and minimize costs.

  • 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.

  • Fast Wet Out

    Allows the processor to optimize part production speed resulting in increased productivity and reduced costs

  • High Burst Strength

    Excellent glass/resin bonding, which provides high burst strength in pipe or vessels.

  • Corrosion Resistance

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

  • Filament Winding Applications In Epoxy And Phenolic Resin Systems

    <ul> <li>High pressure pipe and pressure vessels, where high strength and high burst pressure are required</li> <li>CNG and LPG tanks</li> <li>water purification</li> <li>woven roving for ballistics (NA)</li>

Owens Corning Composite Material patented Track-Pak® packaging provides virtually 100% transfer efficiency, which minimized downtime and cost.

Rovings are available in a single-end internal-pull package. Pallets are stretch wrapped for load stability. Each doff is wrapped for protection and to aid strand run-out and transfer. Pallets are available in bulk or Creel-Pak® pallet packaging format, depending on region. More information is available from Owens Corning Customer Service and Sales.


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


It is recommended to store glass fiber products in a cool, dry area. The glass fiber products must remain in their original packaging material until the point of usage; 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 season. The packaging is not waterproof. Be sure to protect the product from the weather and other sources of water. When stored properly, there is no known shelf life to the product, but retesting is advised after three years from the initial production date to insure optimum performance.
