Extrusion polyamides

Polyamides are semi-crystalline polymers with high viscosity, strength and hardness. Products made from virgin polyamide have excellent surface gloss, a low coefficient of friction, high impact strength across a wide temperature range, resistance to alternating loads and very high tensile strength. The main global consumption of polyamide is associated with the production of textile yarns. The material names “nylon” and “kapron”, common in everyday use, are trade names of fibre-forming polyamides of Western concerns. The modern packaging industry cannot be imagined without polyamide. The barrier properties of this material protect foodstuffs from oxidation, blocking oxygen and most gases. A layer of polyamide in films compensates for the gas permeability of polyolefins. The high strength properties and performance under environmental conditions are usually attributed to the presence of amide groups —C(O)-NH-, which are linked to one another by hydrogen bonds. Global consumption of polyamide is approaching 8 million tonnes per year. About 40% of polyamides are used in industry as feedstock for the production of compounds, whose largest consumers remain the automotive industry, electrical engineering and electronics. It ranks 3rd to 5th in engineering plastics consumption volume after PC and ABS. Material Wizard supplies base injection-moulding and extrusion-grade polyamides — technical grades as well as grades with food and medical approval.
