0 SHORT ROLLS

  • +50% higher tensile strength

    Increased dry tensile strength reduces tear outs and provides a wider process operating window.

  • 50% tighter weight control

    Enhanced mat weight consistency helps ensure process
    and part-to-part consistency.

  • IMPROVED ROLL LENGTH

    +10% longer rolls and no short rolls offer longer run time on creels, increased slitting efficiency, and more efficient use of warehouse space.

Applications

M8643 Pro mat is compatible with unsaturated polyester and vinyl ester resin systems and designed primarily for the reinforcement of pultruded shapes, including gratings, ladder rails, frames, and insulators.

Technical Information

Availability

M8643 Pro is available in North America. Additional weights and widths are available upon request by contacting your Owens Corning representative.


Packaging & Labeling

Each roll is wound on a 101.6 mm (4”) inside diameter paper tube, fully enclosed in Creel-Pak™ wrap, positioned vertically on each pallet, and Cling-Pak™ wrapped. To allow 100% traceability once the roll is slit, information is printed onto the wrapping film and the core paper tube.

Each roll bears a label detailing the product description, product code, nominal weight, roll width, roll number, and date of manufacture.

Storage

Unless otherwise specified, it is recommended to store glass fiber products in a cool, dry area. Ideal conditions are at a temperature between 10°C and 35°C and a relative humidity between 35% and 85%. The glass fiber products must remain in their original packaging material until the point of usage. If the storage temperature is below 15°C, it is recommended that the product be stored in the workshop, within its original packaging, at least 24 hours prior to use to help 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.
