Type 30™ single-end roving

ST2070LS

FOR GLOBAL NOISE CONTROL SOLUTIONS

MATCH EMISSION REGULATIONS

ST2070LS Type 30™ roving is specifically designed for use in the Silentex® Exhaust filling process. ST2070LS was developed to match stringent global emission regulations on particulate matter.

Performance Attributes

ENHANCED SERVICE LIFE & DURABILITY
EXCELLENT PROCESSING
CONSISTENT PERFORMANCE
  • Enhanced Service Life & Durability

    • Advantex® glass provides longer service life with a high temperature composition specifically engineered for use in the Owens Corning Silentex® process, which minimizes process interruptions and ensures overall product efficiency. <br> <br> • Fibers remain continuous and resist blowout with five times the strength of basalt wool and twice the strength of E-glass under the most corrosive conditions. <br> <br> • Glass annealing point ≥ 720°C (according to ASTM C336). <br> <br> • Based on the available data and experience, it is recommended to use ST2070LS at a maximum continuous glass temperature of ~740°C.

  • Excellent Processing

    • Smooth run-out from lower drag across contact points produces less fuzz, resulting in smoother parts, less clean-up, and improved machine efficiencies.

  • Consistent Performance

    • Narrow and consistent fiber diameter distribution for reliable sound absorption for reduced fill density compared to basalt preforms or needle felt.

APPLICATIONS

ST2070LS is designed for use in the manufacture of cost-effective automotive muffler systems with optimal durability and acoustic performance.

Each pallet can be packaged in bulk or Creel-Pak™ packaging format. Pallets are stretch wrapped for load stability and for protection during transport. All individual packages are wrapped with Tack-Pak™ packaging to aid package run-out and transfer. More information is available in the Customer Acceptance Standards.

Labeling

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

Storage

Unless otherwise specified, 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 in its original packaging for 48 hours prior to its utilization to allow it to reach the workshop temperature condition and prevent condensation. 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 ensure optimum performance.
