Thermal Conductivity Measurements of Polyamide 12
2011An important component in understanding the laser sintering process is knowledge of the thermal properties of the processed material. Thermal conductivity measurements of pure polyamide 12 were conducted based on transient plane source technology using a Hot Disk® TPS500 conductivity measurement device.

Colorometric study of polyamide-12 powder aging
Industrial laboratory. Diagnostics of materials, 2020The key point of 3D printing by selective laser sintering is the necessity of complete filling of the working chamber of the printer with a powder material. Since the powder is not completely consumed during the printing process, 25 – 30 wt.% of secondary (unused in the previous cycle) power is added to the primary material in each cycle.

Laser sintering of polymers is widely used for the production of individual products and small-batch series. However, the qualification of laser-sintered polymeric components for new application fields, e.g. in the food and packaging industry, is still limited due to missing knowledge on physicochemical material properties.

Experimental Study on Laser Plasticizing Polyamide 12
Advanced Materials Research, 2012Considering the efficiency and microscale requirement of melting polymer in micro-injection process, we present an experimental analysis of the CO2 laser irradiating Polyamide 12 (PA12) based on the photo-thermal effect of laser-materials interaction. The orthogonal experiments of laser plasticizing were designed by Taguchi method of Minitab software ...

Investigation of structure development in polyamide 11 and polyamide 12 tubular film extrusion
Polymer Engineering & Science, 2002AbstractThe processability of single bubble polyamide 11 and polyamide 12 films was investigated. The development of crystalline structure and chain orientation of polyamide 11 and polyamide 12 films in single bubble film blowing was studied by differential scanning calorimetry (DSC), wide angle X‐ray diffraction (WAXS), infrared (IR) spectroscopy, and

Generalization of the static mechanical properties of plasticized polyamide-12 and polyamide-6
Polymer Science U.S.S.R., 1989Abstract Generalization of the static mechanical properties of plasticized PA-12 andthe method of reduced variables over a wide temperature range has yielded a discrete series of values of the effective activation energy corresponding to the main relaxation processes. The character of change in effective activation energy with strain is regarded as a
