Crystalline properties of injection molded polyamide-6 and polyamide-6/montmorillonite nanocomposites

Applied Clay Science, 2009
Abstract This paper presents a study of the crystalline properties of injection molded samples of polyamide-6 (PA6) and polyamide-6/montmorillonite nanocomposites (PA6 MMT). Processing conditions and tool temperature during injection molding affect the crystal structure and the crystallinity of the samples.

Studies on Molecular Composites of Polyamide 6/Polyamide 66

Macromolecular Rapid Communications, 2004
AbstractSummary: A series of molecular composites of PA 6/PA 66 was synthesized via in situ polymerization. The impact resistance of PA 6 was improved dramatically by incorporating a minor amount of PA 66 (2–10 wt.‐%), without decreasing the tensile strength.

Crystallisation behaviour of Polyamide-6 and Polyamide-66 nanocomposites

Composites Science and Technology, 2006
The crystallisation properties of injection moulded Polyamide-6 and Polyamide-66 nanocomposites based on organophilic layered silicates were investigated by differential scanning calorimetry and X-ray diffraction to better understand the influence of the nanoplatelets on these two matrices.

Axial fatigue behaviour of polyamide-6 and polyamide-6 nanocomposites at room temperature

Composites Science and Technology, 2008
Abstract Design against fatigue requires thorough understanding of the underlying fatigue mechanisms and factors influencing them. The objective of the present work is to study the effect of nanoclay addition on the temperature rise and modulus drop during cyclic loading in polyamide-6 and polyamide-6 base nanocomposite.

Investigation of thermal degradation and flammability of polyamide‐6 and polyamide‐6 nanocomposites

Journal of Applied Polymer Science, 2007
AbstractIn this paper, polyamide‐6 and polyamide‐6 nanocomposites were prepared by direct melt intercalation technique. The thermal degradation behavior of both polyamide‐6 and polyamide‐6 clay nanocomposites has been studied. The apparent activation energy of the nanocomposites is almost the same with that of pure polymer under nitrogen, but the ...

Microinjection molding of polyamide 6

Polymers for Advanced Technologies, 2014
Processing polymers by microinjection molding (μIM) generate specific constraints upon the polymer melt such as high shear stress and rapid cooling, leaving a mark upon the microstructure of the micropart. The present work compares the morphology and structure of polyamide 6 samples produced by melt extrusion and μIM.

HALS in polyamide 6 polymerization

Macromolecular Symposia, 2003
AbstractThe use of Hindered Amine Light Stabilizers (HALS) directly in polyamide 6 polymerization can cause some problems. The following two problems were the focus of our project:1) We investigated, from a theoretical point of view, the results of introducing directly one of the precursors of HALS into polyamide 6 polymerization. For the investigation,

Effect of polyamide 6 on the mechanical behavior of thermoplastic polyurethanes/polyamide 6 blends

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 2021
Ductility and tensile strength are among the basic mechanical properties of polymers. Generally, it is difficult to enhance the ductility without significantly reducing the tensile strength. In this study, thermoplastic polyurethane (TPU) is mixed with 0%, 2.5%, 5%, 7.5%, 10%, and 12.5% polyamide 6 (PA6).

Phase behaviour in ternary polyamide 6/polyamide 66/elastomer blends

Polymer, 2000
Abstract The phase behaviour of the ternary blend system polyamide 6/polyamide 66/elastomer has been interpreted by the binary interactions of the respective polymers. Three different elastomer components have been studied; random ethene–propene copolymer (EPM), ethene–propene–diene copolymer grafted with maleic anhydride (EPDM- g -MA) and ethene–1 ...
