PA is a thermoplastic with excellent strength and toughness, in addition to high wear resistance and good sliding properties. Polyamide is available in several models, with PA6 and PA6.6 being the most common. PA is used for household items and technical parts, which must have a high resistance to abrasion, as well as in mechanical engineering and vehicle construction.
Polyamides (PA) are thermoplastics whose monomers are derived from basic aliphatic bodies. The two most frequently used polyamides are PA 6 and PA 6.6, whose manufacturing process is fundamentally different. Polyamide 6 is formed by ring opening polymerization. Polyamide 6.6 is formed by polycondensation with water elimination. PA6 and PA6.6 can be welded together. Due to its resistance to lubricants and fuels at higher temperatures, PA is also often used for engine accessories such as fuel and intake systems, covers and linings. Polyamides can be processed with all the usual processes for thermoplastics, such as welding, extrusion and injection molding.
