  • Easy handling and moldability

    Optimized bonding and chop length mix bring high conformability and easy hand tearing for tailored shapes.

  • Process efficiency

    Fast wetting and quick air release maximize molding productivity. <br> Excellent weight uniformity helps laminate consistent thickness.

  • Enhanced service life

    Compared to standard E-glass, Advantex® glass helps with enhanced service life in applications facing corrosion.


Deep draw molding (railway transport) - Matched metal die wet molding (dielectrical parts).

M720 mat is designed for hand lay-up process with polyester, vinyl ester resin systems. Applications include deep draw and complex molding with highly filled resin systems and matched metal die wet molding, for example in rail transport or dielectrical part manufacturing.

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.
