FR-KPBS is extremely effective as a flame retardant additive with premium performance
in polycarbonate at very low additive levels.
FR-KPBS has been found to be an effective
flame retardant in polycarbonate at use levels as low as 0.06%~0.08% by weight.
It is
chemically and thermally stable to temperatures greater than 450℃, making it suitable
for use in engineering resins that require high provides excellent performance without
affecting the processability of the resin.
One advantage of the low use levels necessary to provide effective flame retardance is
that FR-KPBS flame retardant additive can be formulated to produce optically-clear,
haze-free grades of polycarbonate for extrusion and molding.
What's more, FR-KPBS additive
does not contain any bromine or chlorine and has been found effective as a flame retardant
without the use of synergists.
For most effective incorporation it is recommended that the additive be initially dispersed
into a 10% or more masterbatch and then compounded into the final plastic blend.
Dispersion
can be achieved effectively with typical polycarbonate processing equipment.
