1. PC/ABS & ABS grades offer enhanced processability.
Three new grades within the Magnum 4400 series appear to always be able to overcome standard
problems associated along with flame-retardant ABS, for example mold plateout as well as restricted
light-stability selection. Magnum 4410, 4420 and 4430 supply a choice from medium in order to
substantial uv stability. The Actual range permits consumers to select probably the actual most cost-
effective resin according to particular light stability requirements. Rates range from $1.91 in order
to $2.01/lb tl inside custom colors. Almost All three grades possess UL 94V-0 performance in 1/16
in., due for you to a http://www.howtogetsixpacksabs.com/female-six-pack-abs/ proprietary bromine
additive package which addresses health concerns simply by not which includes brominated
diphenylether, according to the company.
Magnum 4410 comes using an HDT regarding 160 F at 264 psi, melt-flow charge of 11 g/10 min,
flexural modulus involving http://www.howtogetsixpacksabs.com/female-six-pack-abs/ 320,000 psi,
notched Izod impact associated with 3.5 ft-lb/in., and elongation regarding 30%.

FLAME-RETARDANT ABSs OFFER UV CHOICE
The http://www.howtogetsixpacksabs.com/11-ultimate-ab-ripper-x-workout-exercises/ Dow Plastics
unit regarding Dow Chemical U.S.A., Midland, Mich., will be introducing four grades involving
resins pertaining to injection molding enclosures regarding enterprise machines. The Actual new
supplies tend to be believed to supply improved processability compared to contending flame-
retardant resin systems.
Pulse 1735 has an HDT regarding 195 F from 264 psi, notched Izod impact regarding 12 ft-lb/in.,
2. along using a melt-flow price associated with 28 g/10 min--values comparable to or perhaps slightly
a lot far better than these associated with Pulse 1725. Dow sources say Pulse 1735's flowability is
simply slightly less than 1725's in terms of real-world injection shear rates. Dow claims that will
Pulse 1735 delivers an improved balance regarding HDT, impact as well as processability when
compared with additional nonhalogenated PC/ABS business-machine grades on the market,
including absolutely no plateout. Pulse 1735 can be priced with $2.07 lb/tl throughout custom colors,
which is competitive along with other nonhalogenated PC/ABS's as well as 2|cents~ lower than Pulse
1725.
NONHALOGEN ALTERNATIVE
Dow executives the objective throughout developing the new grades was to offer a new competitive
stability regarding processing as well as mechanical/thermal properties, together with improved uv
resistance along with surface appearance, as well as higher heat-distortion resistance for thinner-
walled parts.
Dow says the actual Magnum 4400 series significantly minimizes plateout compared with equivalent
contending FR-ABS resins. Dow additionally cites lower melt viscosity, which permits molding in
lower temperatures (around 400 F melt), potentially yielding 10-25% shorter cycle times.
New Pulse 1735 PC/ABS grade features a completely nonhalogenated flame-retardant package as an
alternative to Pulse 1725, containing bromine. This kind of is said to offer with a quantity of
business-equipment manufacturers' choice to be able to stay away from halogen, however without
virtually any sacrifice regarding processability or performance properties. Just Like Pulse 1725, your
1735 grade achieves UL 94V-0 flammability from 1/16 in., and also meets UL 94-5VA in 1/8 in. the
patented flame-retardant package consists of phosphorus as certainly 1 of its components.

The 4 grades represent new-generation extensions involving Dow's Pulse polycarbonate/ABS blend
and also Magnum ABS item lines. Your organization last updated these two resin series pertaining to
enterprise device software in late 1989 with almost all the introduction of Pulse 1725 and also
Magnum 3661.
