New Additives for Improving Flow In Nylon


Two new additives from AXEL, MoldWiz® INT-PA33FRK (a liquid additive), and MoldWiz® INT-38F (an additive in pellet form) have recently been evaluated with excellent results.  The flow additives were loaded at 3 parts /1000 based on weight utilizing liquid or pellet feeders as appropriate.

 The first and most important observation was that both additives enabled resin to be injected on average at 10°F lower temperature than previously. In addition to exhibiting good flow at lower temperature, crystalinity was also excellent, enabling the cooling cycle of the injection process to be reduced on average 12.5%. These factors contributed to an overall cycle time reduction which correlated to a 4-7% increase in the number of parts produced.
