PA (Polyamide)

What is PA (Polyamide)?

It is a synthetic polymer that occurs both as an engineering plastic and as a fiber, where it is used in everything from industrial components to textiles such as nylon. Thanks to its high performance, PA is a common material in demanding applications where wear resistance and durability are crucial.

Important properties of PA (Polyamide)

• High mechanical strength and stiffness – PA has excellent strength and can withstand high loads.
• Excellent wear and abrasion resistance – Perfect for moving parts and mechanical components.
• Good chemical resistance – Resists many oils, greases and solvents, making it useful in technical and industrial applications.
• High heat resistance – Can withstand temperatures up to approximately 120–150°C depending on the type of PA.
• Low friction – Very good sliding properties, making it suitable for bearings, gears and other moving parts.
• Moisture absorption – PA can absorb moisture, which can affect its mechanical properties. Therefore, it is often used in dry or controlled environments.
• Good impact resistance – Withstands shocks and mechanical stress without cracking.
• Easy to process and injection mold – Can be manufactured by injection molding, extrusion and turning.
• Recyclable – PA can be recycled and reprocessed, making it a more sustainable alternative.

Different types of PA (Polyamide) and their uses

There are several different types of polyamide, the most common of which are:

• PA6 (Polyamide 6) – Good impact resistance and flexibility. Used in gears, plain bearings, pipes and cable protection.
• PA66 (Polyamide 66) – Higher stiffness and temperature resistance than PA6. Common in mechanical components, automotive parts and industrial tools.
• PA12 (Polyamide 12) – Low moisture absorption and high flexibility. Used in hoses, cable protection and sensitive technical parts.
• Fiber-reinforced PA variants – PA can be reinforced with glass fiber or carbon fiber to increase stiffness and durability. Used in high-strength industrial and automotive components.

How do we use PA (Polyamide) in our production?

We use polyamide (PA) in a range of technical and industrial applications, where its mechanical and chemical properties make it the optimal choice.

Some of the most common uses are:

• Industrial components – PA is used in wear-resistant and durable parts such as gears, plain bearings and spacers.
• Automotive industry – PA is used in engine mounts, cooling system components, fuel systems and interior details thanks to its combination of heat resistance and wear resistance.
• Machine parts and technical components – PA is used in machine components that require low friction and high wear resistance, such as bearings and guide rails.
• Sports and leisure – PA is used in protective equipment and technical details in sports equipment, such as ski bindings and bicycle parts.
• Electronics and wiring – PA is used in connectors, cable protection and insulating components.

Why do we choose PA?

Polyamide (PA) is one of the strongest and most durable plastic materials on the market. Its high wear resistance, chemical resistance and temperature resistance make it an ideal solution for industrial and technical applications.

To optimize PA for different purposes, it can be modified with:

• Fiberglass reinforcement – Increases stiffness and durability.
• Oil additives – Improves sliding properties and reduces friction.
• UV stabilizers – Protects against degradation during outdoor use.

In summary, PA is a versatile and high-performance material used in a range of products where durability and wear resistance are crucial.
