Flame Retardant Sponge UL 94 V-0 - Norseal R10400 M

Flame Retardant Sponge UL 94 V-0 - Norseal R10400 M

Flame Retardant Sponge UL 94 V-0 - Norseal R10400 M

Our Flame Retardant closed cell sponge recognized to UL 94 V-0 requirements. This product is available in seven different thicknesses and delivers medium firmness, making it suitable for a wide range of gasketing applications.

The material is flexible and compressible with excellent weather ability and non-stick properties. In addition  R10400 M is post cured to minimize volatiles for a clean gasketing application.

R10400 M utilizes the high consistency silicone rubber (HCR) chemistry. The provides superior mechanical strength properties such as improved tear strength, abrasion resistance and strength over other silicone rubber systems. Through the HCR process maintains a very uniform closed cell structure ensuring enhanced sealing properties. The speciality formulation is also designed for use in extreme temperature applications (-73 to 260 degrees Celsius) allowing the specifying engineer a wide latitude.

Important Instructions:

  • Because Elder Tapes and Rubber cannot anticipate or control every potential application, we strongly recommend testing of this product under individual applications conditions prior to commercial use.
  • Surfaces must be clean and free of oil, grease, moisture, dust and dirt. Isopropyl alcohol is good for cleaning the surface. Do not remove the liner until tape is in proper position, avoid touching adhesive surface before application.
  • Recommended service temperature of base sponge is -73 to +260 degrees Celsius.
