Designers conceptualized a new, larger version of the
Soldier’s model, including 10 tools, a lock blade that can
be opened with one hand and, importantly, a non-slip
handle manufactured from a combination of hard and
soft thermoplastics.
Achieving the non-slip handle Victorinox envisioned
required a soft material for the new grip areas that
would chemically bond to a rigid polymer underneath.

Cesa™ Fiber Additives for stain resistance efficacy
are non-fluorine additive concentrates developed
for incorporation in the yarn during extrusion.
APPLICATIONS
Cesa stain-resistant solutions are suitable for
polyester fibers used in automotive textiles, home
and office furnishings, and carpets and rugs.
WORKING PRINCIPLE
Cesa stain-resistant concentrates prevent soils from
setting in the fibers making it easier to remove stains
with common household cleaners such as wipes,
sprays, and steam cleaners.

After
developing a deep understanding of the customer’s
needs, Avient’s team quickly went to work to formulate
a custom OnColor™ color and then added Cesa™
WithStand™ antimicrobial technology to make a
single Smartbatch™ masterbatch that passed all of the
product’s challenging requirements.
This combined
additive and color technology not only solved the color
harmony challenge across all polymers used in the
various components of the personal care device, but
also accelerated testing because the Cesa WithStand
antimicrobial material used had been pre-tested for
polymeric integrity.
Avient has compiled extensive data
that enabled the OEM to shave weeks off the product
development timeline and save nearly $50,000 in
potential antimicrobial product protection testing fees.

VALVE-GATED TOOLS IN
INJECTION MOLDING GUIDELINES
CESA
CLEAN ADDITIVES
™
KEY FEATURES
Cesa™ Clean Additives
• Cesa Clean is a concentrated purge product, not a purge compound.
• It can be processed through manifolds, valve-gated tools and small sub gates.
• Cesa Clean is 100% recyclable with polyolefin resins and compounds.
GUIDELINES FOR USING CESA CLEAN ADDITIVES
• Cesa Clean works best when molded maintaining normal (injection)
pressure/shear
• For best results, Avient recommends a “Running Color Change”
which eliminates breaks in the molding cycle
• Since the Cesa Clean concentrate will expand, it is recommended
to reduce the shot size by 20%
• It is designed for use at a let-down ratio (LDR) of 3.0% or (33:1); however,
use rate can vary depending on the severity of the contamination but
typically is 2.0–4.0% (a use rate higher than 6.0% may not have any
positive affect on the cleaning performance)
• Using Cesa Clean as a routine part of your color change rotation will
allow faster changes and consume a minimal amount of raw material
- Note: If the manifold is not cleaned routinely, this process may be
more time consuming and additional material will be required
• It is best to process at your normal polymer processing temperatures
- For best performance, stock temperature should be at least 400°F
- If 400°F is achieved during the purging process, no additional
activation will occur during the reprocessing of regrind
- All parts produced during the “Running Purge Cycle” should be
captured as regrind, resulting in a scrap-free color change
- If using sequential gates, open and close all gates at the same time
while purging the tool
- If contamination appears to be coming from one gate, open and
close first, and for an extended period of time, to force more material
through this location
- When cleaning in this manner, pay close attention to shot size
- Parts containing the previous or new color plus any Cesa Clean
can be used as regrind
INTRODUCING CESA CLEAN TO YOUR PROCESS
Hand Blend
• Hand weigh enough of the Cesa Clean and
natural resin mix to equate to 3–5 times the
barrel capacity
• Use rate should be 3.0% or 33:1 for routine
cleaning
• For difficult-to-clean tooling, or tooling which
is not routinely cleaned, start at 4.0% or 25:1
• Note: Do not attempt to vacuum load more than
15 feet from source as stratification/separation
may occur
Volumetric Feeder
• Calibrate feeder to dispense 3.0% or 33:1 for
routine cleaning
• For difficult-to-clean tooling, or tooling which
is not routinely cleaned, start at 4.0% or 25:1
• This style of feeder is highly recommended for
at-the-throat metering of Cesa Clean
Blending Units
Most blenders have an extra bin for an additive
• Fill the additive bin with Cesa Clean
• Set blender to introduce the Cesa Clean at
2.0 to 4.0%
• Note: Do not air convey any further than 15 feet
as Cesa Clean has a high density and may separate
from the mix.
GETTING STARTED
TIMING IS THE KEY TO A RUNNING
COLOR CHANGE
Hand Blend
• Have the purge blend ready to load
• If hopper contains a mixture of resin, color and/
or regrind, it should be run dry or drained before
beginning the color change, keeping the screw
full so press cycle continues
• Run the main resin hopper dry or shut off hopper
to hand feed at the throat
• Once press is clean, slide hopper in place
and proceed with next color-resin blend
• The next color can be added while Cesa Clean is
still in the barrel
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
(Single) Volumetric/Gravimetric Metering Unit
at the Throat
• Empty and clean feeder while press continues
to run
• Add Cesa Clean to the feeder color hopper and
calibrate to a 3.0% use rate
• When press is clean, start next color
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
• Note: If an open/unused secondary feeder is
installed, use it for the Cesa Clean concentrate
Central Blending Unit
• Thoroughly clean unit while continuing to mold
parts, keeping a resin feed to the press
• Using a clean open hopper or regrind hopper, add
the Cesa Clean concentrate
• Set blender for additive/color to 3.0%
• Once press is clean, drain hopper and/or central
blending unit while continuing to mold parts
• Begin new color and continue to mold parts
• When splay is no longer visible in parts, reset shot
size, parts should be ready to pack
Process Adjustments That Can Help
• Increase back pressure
• Increase screw speed
• Increase injection speed (in some tools maximum
injection speed can facilitate cleaning)
• Reduce mold close time (faster cycle)
• Always remember a stock temperature of 400°F
is essential
When press and tool are clean, return all settings to
standard production process profile.
