Continuous Filament Mat

Unifilo® 801- 809


U801/U809 continuous filament mats represent specific solutions to homogeneously reinforce expanded polyurethane foam.


Performance Attributes

  • Customized For P U Foam Process

    U801/U809 specific design helps to even mat expansion during the PU foaming process. <br> U809 is compatible with CO2 blowing agent used in insulating material manufacturing process. Excellent glass/polyurethane bonding brings improved mechanical performance and dimensional stability to the PU foam. <br> U801 superior drapability fits the most complex mold shapes.

  • Corrosion Resistance

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



U801/U809 mats are compatible with polyurethane resin systems and designed for PU foam reinforcement process. U809 is suited for LNG (Liquified Natural Gas) carrier cryogenic insulating systems. U801 is recommended for PU foam reinforcement in replacement of wood structure, in housing and recreational vehicle applications. (Image copyright Fotolia. For application illustration only.)

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, the product can be used up to 2 years from the date of manufacture, and retesting is advised after 1 year from the initial production date to insure optimum performance.
