This also influences how much moisture PA absorbs, in turn having an effect on dimensional accuracy and mechanical properties. The physical properties are differentiated by the composition and structure of their molecule chains. There are extruded and cast metals; the latter can be produced in larger dimensions, has lower inner tension, and a higher degree of crystallisation (more solid). Polyamides feature a very good range of mechanical properties, particularly high impact resistance, and excellent sliding and wear behaviour. The properties vary here from the hard and tough PA 6.6 to the soft and flexible PA 12.
This material offers an optimum combination of mechanical strength, rigidity, impact resistance, and mechanical damping, in combination with very good wear resistance, good electrical insulation properties, and good chemical resistance. PA 6 extruded is therefore a universal material for construction and maintenance.
PA 6 reinforced with 30% glass fibres demonstrates increased strength, rigidity, creep strength, and dimension stability compared to non-reinforced PA 6.
PA 6 G is manufactured in a pressureless casting process. It therefore has lower internal tensions.
This cast polyamide features integrated lubrication and features considerably wider application options; its self-lubrication results in improved sliding properties.
This modified polyamide contains finely distributed molybdenum disulphide particles that have a positive effect on wear and sliding properties. Perfect for gear wheels!
This heat-stabilised cast polyamide has a better resistance to thermal oxidative breakdown, enabling it to be used in constant service temperatures 15 to 30°C higher. Particularly recommended for service temperatures above 60°C.
The addition of PE has an enhancing effect on the friction behaviour.
This is a special cast polyamide with a distributed, integrated, solid lubricant that offers outstanding wear resistance as well as an extraordinarily dynamic load capacity.
This material features an increased toughness, flexibility, and fatigue strength.
Nylatron 703 XL features even better wear resistance than Nylatron NSM and is combined with higher dynamic load capacity and above all with lower stick-slip susceptibility.
This material was developed for the high inflammability demands of plastics. The product complies with V-0 criteria from a thickness of 1 mm and it fulfils the requirements of DIN EN 45545-2. It is most commonly used for fire prevention in rail vehicles.
Ertalon LFX is a cast polyamide with integrated lubrication for self-lubrication. Thanks to its low friction coefficient (up to -50%) and its high wear resistance (up to 10x), it offers considerably more application areas.
PA 4.6 is a semi-crystalline thermoplastic with very high heat deflection temperature. Its enhanced rigidity and creep strength make this material suitable for use in a wider range of temperatures. It also features considerably higher thermal aging resistance in higher temperatures (80-150°C) than all PA types, even POM and PETP.
A material that offers good rigidity, hardness, abrasion resistance, and heat deflection temperature. PA 6.6 has benefits compared to PA 6. Compared to the cast version, PA 6.6 has higher moisture absorption. In its other characteristics, PA 6.6 is similar to the cast PA 6 G, but 60% more expensive.
PA 6.6 reinforced with 30% glass fibres demonstrates increased strength, rigidity, creep strength, and dimension stability compared to non-reinforced PA 6.
The addition of Mo52 yields a material with increased rigidity, hardness, and dimensional stability, although impact strength is slightly reduced.
PA 12 is a semi-crystalline polyamide with very high toughness and good chemical resistance. Of all the polyamides, PA 12 sets itself apart with the lowest water absorption. It also possesses good impact strength. It is extruded.
Its properties make this material well-suited for parts with high continuous static loads at higher temperatures. Since glass fibres tend to cause a somewhat significant abrasion of the mating surface, PA 12 GF 30 is less suitable for sliding applications. This PA 12 reinforced with 30% glass fibres demonstrates increased strength, rigidity, creep strength, and dimension stability compared to non-reinforced PA 12.
A multitude of superior properties make PA 12 cast an outstanding engineering material, in mechanical and apparatus engineering, the automobile industry, drive engineering, and the food, printing, paper, and packaging industries, for example.
