These gases form a cellular foam
structure from the inside to the outside of the plastic
part when they are used in an optimized injection
molding process.
Structural foam
molding machines (Figure 1) are equipped with a
plasticizing extruder and a separate transfer cylinder
for quicker injection.

The main reason for the use of Hydrocerol Chemical
Foaming Agents is to achieve weight reduction of
plastic parts, which in turn saves material costs and
supports a more sustainable profile to the molded
part.

Colorants & Additives
Multiple color production
• Depending on the manufacturing set-up, several
injection points can be added to enable multiple
color production at the same time on a single
extruder
Batch size flexibility
• Fiber producers can manufacture anything from
a few kilograms to hundreds of tons using the
same simple process
Rapid color changes
• No extruder contamination and easy color-on,
color-off operation increases color change speed
Waste reduction
• Rapid color changes, precise metering and
the ability to adjust color in-line reduces waste
during color changeovers
Continuous metering & long spin pack life
• High pigment and dye concentrations mean
fewer pack changes are required
• Where color is running low for larger volume
runs, low level metering sensors alert operators
and packs can be changed without disrupting
production
In-line IV adjustment
• Specialist additives are available to adjust
Intrinsic Viscosity (IV) in-line for rPET
applications
• These additives are available as single products,
or can be combined with color to create a multi-
functional formulation
Color design service
• Avient offers a dedicated color design service to
help shorten product development cycles and
enhance market agility
Liquid color processing
• Formulations are stable at temperatures up
to 60°C and retain good flow properties at
temperatures as low as 10°C
• These formulations can help lower yarn friction
and abrasion, and there is no fuming
or evaporation during production
Avient’s liquid fiber colorant technology combines advanced liquid color
formulations with state-of-the-art, high-pressure metering equipment to
enable late-stage injection of liquid color for spun-dyed polymer melt.
It works by injecting liquid color at high pressure into the polymer melt-
flow between the end of the extruder, or melt-pipe, and the spin head.
The extruder is never contaminated with color which translates into faster,
more efficient color changeovers that make low volume and custom color
production a reality.

Precautions: the extruder should not be idle with the material in the barrel,
bleed constantly when possible.
