PA6 polyamide is a hard material, highly resistant to wear and impact, with good friction properties, used in many industrial applications. It can be delivered in the form of extruded sheets, bars or tubes.
Polyamide (PA6) semi-finished products have high wear and abrasion resistance, very good friction characteristics and very high resistance to impact and breakage.
Products made of PA6 polyamide successfully replace parts made of bronze, aluminum and other non-ferrous materials. PA6 polyamide is 7.5 times lighter than bronze at the same sheet thickness, but has similar mechanical properties and is much more economical.
PA6 polyamide semi-finished products absorb moisture during storage. Absorbed moisture influences the mechanical and electrical properties (e.g. increases the impact resistance) as well as the dimensional stability of the machined parts (for high precision parts this aspect must be taken into account in the design of the product).
As standard, PA6 polyamide can be delivered in natural white color or in black color. Black PA6 has molybdenum bisulfide (MOS2) additives, which makes black PA6 polyamide semi-finished products to have improved friction characteristics, UV resistance and high tensile strength. Also, depending on the requirements of each application, different additives can be introduced at the time of producing the polyamide semi-finished products to improve certain mechanical properties.

moisture absorption influences the mechanical and electrical characteristics
moisture absorption improves impact resistance and cracking resistance
moisture absorption influences the dimensional precision of machined parts
Other types of PA6 polyamide
In order to be used in certain special applications, PA6 polyamide semi-finished products are improved by adding special additives, which improve certain mechanical properties.
PA6.6 polyamide – has good resistance at high temperatures and high tensile strength. It is the hardest and most rigid type of polyamide-based plastic. The main characteristics are resistance to fuels, oil, grease, most organic and alkaline solvents. Moisture absorption is lower than in PA6. It is used on parts that are exposed to high mechanical loads at high temperatures.
Common applications: friction bearings, gears, cams, guides, sleeves and parts subjected to high loads or high temperatures.
PA6.6 + 30%GF polyamide is PA6.6 reinforced with 30% fiberglass. This material has a very high wear resistance, high strength and rigidity, high cracking resistance, good dimensional stability and can be used at higher temperatures.
It is used when the part must withstand an increased load combined with good friction characteristics.
Specific applications: parts for machines working at high temperatures, sliding bearings, levers, thermal insulators and spacers.
Processing of polyamide semi-finished products
