3M¢â Flame Retardant Additive FR-2025 is
chemically and thermally stable to temperatures
greater than 450¢ªC and is therefore suitable
for use in engineering resins that require
high processing temperatures.
FR-2025 flame retardant additive has been
found an effective flame retardant in polycarbonate
at levels as low as 0.06-0.08% by weight.
Due to the low levels required to achieve
performance and its effective solubility in
polycarbonate, FR-2025 additive can be formulated
to produce an optically clear, hazefree grade
of polycarbonate for extrusion and molding.
Excellent flame retardant performance can
be achieved without affecting the processability
of the resin.
FR-2025 additive does not contain any bromine
or chlorine and has been found effective as
a flame retardant without the use of synergists. |

3M¢â Flame Retardant Additive FR-2025 is
extremely effective as a flame retardant additive
with premium performance in polycarbonate
at very low additive levels.
There is limited data to suggest that flame
retardant additive FR-2025 may have utility
at varying performance levels and higher addition
levels in other engineering resins.
For most effective incorporation it is recommended
the additive be initially dispersed intoa
10% or more masterbatch and then compounded
into the final plastic blend. Dispersion can
be achieved effectively with typical polycarbonate
processing equipment. |
