3M™ Flame Barrier FRB-NC Series
Data Sheet
Description
November 2012
3M™ Flame Barrier FRB-NC Series provide the high flammability resistance, arc resistance,
and dielectric strength to help safely contain electrical hazards.
These barriers are available in roll or sheet form.
The flame barrier FRB-NC series provide 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.
Applications
The flame barrier FRB-NC series provides both electric shock and flame protection for
electrical and electronic device applications such as:
General purpose lighting luminaires (including LED type)
Battery housing barrier (including electric and hybrid vehicles)
Appliance enclosure or insulation of live parts
The flame barrier FRB-NC series is:
An inorganic-based, halogen free material (see regulatory section)
UL 94-5VA rated - the most flame retardant UL 94 rating, even better than UL 94V-0
Dimensionally stable – minimal to no shrinkage at elevated temperatures
Available in thicknesses from 5 to 16 mil (0.127 to 0.406 mm)
The flame barrier FRB-NC 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.

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.
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.

Flammability
The UL 94 test method is used to classify materials based on results from specified small-
scale flame tests. These classifications (5VA, 5VB, V-0, V-1, V-2, HB), listed in decreasing
order of flame resistance, are used to distinguish a material's burning characteristics after
test specimens have been exposed to a specified test flame under controlled laboratory
conditions. These classifications typically apply to materials used in manufacturing
enclosures, structural parts, and insulators found in consumer electronic products.
A material classified as 5VA or 5VB is subjected to a flame ignition source that is
approximately five times more severe than that used in the V-0, V-1, V-2 and HB tests.
Furthermore, specimens in 5VA or 5VB may not drip any flaming particles and 5VA rated
specimens may not develop any burn-through holes during the test.
