2 Nymax Polymer Formulations
Nymax™ and Nymax™ REC Formulations
Nymax™ thermoplastics include prime and recycled nylon formulations in both unfilled grades and
with various levels of glass fiber and mineral reinforcements.
Additional draft may be required
for grained/textured surfaces.
4 Nymax Polymer Formulations
Incomplete Fill
Melt and/or mold
too cold
• Increase nozzle and barrel temperatures
• Check thermocouples and heater bands
Mold design
• Enlarge or widen vents and increase number of vents
• Check that vents are unplugged
• Check that gates are unplugged
• Enlarge gates and/or runners
• Perform short shots to determine fill pattern and
verify proper vent location
• Increase wall thickness to move gas trap to
parting line
Shot size
• Adjust transfer position to 98% full
• Increase cushion
Brittleness
Wet material
• Check moisture.
Degraded/
overheated
material
• Decrease melt temperature
• Decrease back pressure
• Use smaller barrel
• Decrease injection speed
Gate location
and/or size
• Relocate gate to nonstress area
• Increase gate size to allow higher flow rate
and lower molded in stress
Fibers/Minerals on
Surface or Uneven
Surface Appearance
Melt temperature
too low
• Increase injection speed
Insufficient packing • Increase hold pressure and time
Processing Guide 5
Sink Marks
Part geometry
too thick
• Reduce wall thickness
• Reduce rib thickness
Melt too hot • Decrease nozzle and barrel temperatures
Insufficient
material volume
• Increase packing pressure
• Increase gate size
Flash
Injection pressure
too high
• Decrease injection pressure
• Increase clamp pressure

Supplier Code of Conduct
https://www.avient.com/knowledge-base/article/injection-molding-mold-design
In a balanced runner system, the melt flows into each cavity at equal times and pressure.
A good starting point for the gate width should be 1.0 - 1.5 times the gate depth.
If possible, utilize a system or component supplier with experience in styrenic TPEs.

Synthetic esters offer numerous benefits over petroleum-derived mineral oils and other synthetic alternatives such as lower pour point, reduced volatility, better viscosity index, higher flash points and improved biodegradability.
