PA – also known as nylon
PA has an excellent soundproofing effect, helping to ensure a pleasant environment. It also requires little maintenance. PA is used in the food industry, for example, where it eliminates the need to lubricate systems, neatly dealing with the risk of contamination in the foods. The benefits of PA include its low weight and density, which is why it is often used for large machine parts.
In the engineering industry, for instance, PA is used for bearings, cogs, clutches, wire rolls and similar machine parts, where its wear resistance and mechanical attributes are crucial. PA (decrystallised) is an incredibly tough material, making it ideal for using in absorbing elements to dynamic fluctuations. It has high notch impact strength, especially in high humidity conditions. The thermal attributes of PA stretch from -40°C to +100°C.
PA can be welded using all methods commonly utilised for thermoplastic materials. As PA machine parts often have a mechanical function, glue joins must be performed with great care in cases where force is applied to the join. To glue PA to PA, use a solvent including material flakes. To glue PA to steel, it is most common to use a two-component epoxy adhesive.
PA is highly resistant to chemicals, with the exception of acids (generally) and strong bases. PA absorbs a good deal of water, leading to changes in both its mechanical and thermal attributes. Untreated nylon is affected by UV radiation. PA is ideal for application in contact with foods – both in production machinery and for packaging.
PA/nylon is often the preferred option on account of the following benefits:
- Excellent mechanical strength and chemical resistance
- Suitable for use against rough surfaces
- Vibration-damping
- Resistant to most hydrocarbons/solvents and some bases
- Resistant to wear, with a high material fatigue threshold
- Ideal for mixing with other materials. Through modification and reinforcement, PA can be given greater strength and rigidity, resistance to high temperatures and an extremely low friction coefficient.
