Article
Within the injection moulding polyamide composites category, the high impact grades are very well represented. Characterized by a good impact-resistance immediately after their injection. or during their utilization at temperatures below 0°C, these grads are more and more requested, mainly tor technical applications. The main possibilities for gett...
Article
Within the range of the extrudable polyamides, the products including selflubing and thermosetting additives are very well represented. The paper presents one possibility to get high viscosity polyamide 6 having graphite and thermosetting additives, a procedure based on the molecular mass growth following a solid state postpolycondensation in the t...
Article
From the polyamide composites category, processable by injection, the main characteristics of the products containing, as disperse phases, mineral fillings and lubricants, are presented. The poliamides with mineral fillings, as compared to the standard variants, present a good resistance to high temperatures, increased stiffness, low shrinkage at i...
Article
This paper presents the up-to-date state in computer-aided modelling and simulation of the extrusion. There are pointed out the main aspects of this process, which have been taken into account by researchers and for which computer softwares for modelling, simulation and design are commercially available.
Article
In the polyamide range, the products containing carbon fibres (CF), as reinforcement phase, represent a highly used category in the technical applications. In the production process and in the end products characterization step, the CF concentration assessement is a very important aspect. A simple method for CF assessment is determined based on the...

Article
Included in the injection-processable polymeric composites category, the fireproofed polyamide grades are materials in great demand with the plastics processors, due to their multiple applications in various fields. The main possibilities of getting fireproofed polyamides, with or without halogens as fireproofing agents, are presented, rendering ev...
