Description
3M™ Flame Barrier FRB-WT Series is a high, diffuse reflectance coated version of 3M Flame Barrier FRB-NT. The white coating provides greater light reflectance, while the base 3M FRB-NT substrate material from 3M provides high flammability resistance, arc resistance, and dielectric strength to safely contain electrical hazards. These thin and flexible flame barriers are available in roll or sheet form, can be easily converted to produce quality die-cut parts, and assembled into a finished product. The flame barrier FRB-WT series provides the reliability you need from 3M, a trusted company with over 30 years of experience providing insulating solutions that protect people, equipment, and property around the globe.

Features
■ The flame barrier FRB-WT series is:
■ An inorganic-based, halogen-free material (see regulatory section)
■ Coated to provide a white, 90% diffuse reflectance surface
■ UL 94 5VA rated – the most flame-retardant UL 94 rating, even better than UL 94 V-0
■ Available in thicknesses of 5.8 and 8.8 mil (0.145 and 0.225 mm)
■ Dimensionally stable – minimal to no shrinkage at elevated temperatures
■ Low volatile outgassing Regulatory The flame barrier FRB-WT series is:
■ REACH compliant. Product contains no Substances of Very High Concern (SVHC’s) on the REACH candidate lists according to article 59 of Regulation (EC) No 1970/2006 up to June 2012. For current status, go to www.3M.com/REACH
■ RoHS Meets MCVs 2011/65/EU. "RoHS meets MCVs" means that the product or part does not contain any of the substances in excess of the maximum concentration values (“MCVs”) in EU RoHS Directive 2011/65/EU. The MCVs are by weight in homogeneous materials.
■ Halogen Free defined as both 1) no halogen compounds are intentionally added to the product or used in the manufacturing process for the product and 2) any impurities present are less than 900 ppm bromine, less than 900 ppm chlorine, and/or less than 1500 ppm total bromine and chlorine. The latter are the levels set forth in certain industry standards, such as the International Electrotechnical Commission (IEC) 61249-2-21 standard.

■ UL component recognized in accordance with UL 746 file E65069. Flammability The UL 94 test method is used to classify materials based on results from specified smallscale flame tests. These classifications (5VA, 5VB, V-0, V-1, V-2, HB), listed in decreasing

Applications
■ The flame barrier FRB-WT series combines a high, diffuse reflectance surface to maximize light output with both electric shock and flame protection for lighting luminaires (particularly LED type). The excellent thermal stability of the flame barrier FRB WT series is also useful for high temperature labels.
