Aftermarket gun grips made with
materials such as silicone, rubber, or tape can typically
leave residue on a shooter’s hand.
These materials
can also deteriorate with ultraviolet (UV) and chemical
exposure from sunlight and cleaning.
Each tote holds a low-impact, disposable bladder
containing five drums worth of material.

Seeking to
create a more innovative and comfortable insole using
state-of-the-art materials, Gordon and his partner, Jeff
Milliman of Greenville Running Company, went to work.
The fiberglass material, which is less stiff
than carbon, proved to provide greater comfort and
gave the energy return they were looking for.
THE SOLUTION
After extensive research, Gordon found the material
that met his requirements: Avient’s Polystrand™
unidirectional thermoplastic tape.

Equipment
• Feed throats smaller than 2.5" may cause bridging due to pellet size
- Larger feed throats will be more advantageous with long fiber EMI shielding resins
• General purpose metering screw is recommended
- Mixing/barrier screws are not recommended
• L/D ratio
- 18:1–20:1 (40% feed, 40% transition, 20% metering)
• Low compression ratio
- 2:1–3:1
• Deep flights recommended
- Metering zone 3.5 mm
- Feed zone 7.5 mm
• Check ring
- Three-piece, free-flowing check ring
• General purpose nozzle (large nozzle tips are recommended)
- Minimum orifice diameter of 7/32"
- Tapered nozzles are not recommended for long fiber EMI shielding resins
• Clamp tonnage:
- 2.5–5 tons/in2
Gates
• Large, free-flow gating recommended
- 0.25" x 0.125" land length
- 0.5" gate depth
Runners
• Full round gate design
• No sharp corners
• Minimum of 0.25" diameter
• Hot runners can be used
PROCESSING
Screw Speed Slower screw speeds are recommended to protect fiber length
Back Pressure Lower back pressure is recommended to protect fiber length
Pack Pressure 60–80% of max injection pressure
Hold Pressure 40–60% of max injection pressure
Cool Time 10–30 seconds (depends on part geometry and dimensional stability)
PROCESS CONSIDERATIONS
Recommended – retain fiber length (maximize conductivity)
• Low shear process
• Low screw speed and screw RPM
• Slow Injection speed
• Fill to 99–100% on first stage of injection
- Reduces potential nesting of fibers at gate location
- Improves mechanical performance near gate location
- Promotes ideal fiber orientation
Resin Rich Surface
• Achieved when using a hot mold temperature and longer cure times
≥ Max mold temperature recommendation
• Improved surface aesthetic
• Reduced surface conductivity
• Could reduce attenuation performance in an assembly
Fiber Rich Surface
• Achieved when using a cold mold temperature and shorter cure times
≤ Minimum mold temperature recommendation
• Improved surface aesthetic
• Reduced surface conductivity
• Could improve attenuation performance in an assembly

https://www.avient.com/sites/default/files/2023-11/Cesa Clean Processing Usage Guide.pdf
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.
