Product Information

In this article, three different treatment routes were applied and analyzed after injection molding to study the roles of boiling water bath and re-drying in improving the dimensional accuracies and mechanical properties of a plate that was made of PA66-GF25 FR (RP) by performing size measurements, mechanical property tests, and micro-morphology comparisons. Some conclusions are presented here. Structure–property relationships in glass reinforced polyamide, part 2: The effects of average fibers diameter and diameter distribution.

PA6 can absorb up to 7% (by weight) water under high humidity or submerged in water. This can result in dimensional changes up to 2% and a corresponding reduction of physical properties. Proper design techniques can frequently compensate for this factor.

Data availability statement: The datasets generated during and/or analyzed during the current study are available from the corresponding author on reasonable request. From the comparison and analysis of the three routes, it can be concluded that the re-dried plate treated by route II is preferred for ensuring the dimensional accuracies, mechanical properties, and the employment character of the medium voltage environment. 5 Conclusion Influence of water on the short and long term mechanical behaviour of polyamide 6(polyamide) fibres and yarns.
