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.

Cesa™ WithStand™ SX Low Haze Antimicrobial Additives
PRODUCT BULLETIN
Cesa™ WithStand™ SX Low Haze Antimicrobial
Additives counteract bacteria, fungi, and microbes
to enhance the performance of clear polycarbonate
or plexiglass applications that require visual clarity.
The patented formula of Cesa WithStand SX is
especially suited for those products that use recycled
resin, as it will not cause opacity or hazing as
traditional antimicrobials often do.
By limiting the growth of microbes in finished
plastic parts, Cesa WithStand SX can reduce odor
development and protect against staining, hazing,
and discoloration to keep products looking newer.
