Reinforced with glass fibre, polymers are characterised by a high level of rigidity, good dimensional stability, excellent resistance to heat, good resistance to wear, and a low friction co-efficient.
PA 6 and PA 6.6 are extremely similar. In fact, both are partially crystalline and have the same base, but their individual molecules have a different order. For this reason, the basic properties such as chemical resistance are the same in both. Both polymers have good slipping and cushioning properties, good abrasion, and both are also resistant to weak alkalis, greases and oils. The chemical and physical properties of PA6 are extremely similar to those of PA66. PA6 has a lower point of fusion than PA66, and it is also slightly less expansive. The resistance to impact and anti-solubility PA6 is better than that of PA66, but it is also more hygroscopic. Given that many of the quality characteristics of the plastic pieces are subject to hygroscopicity, bear this in mind when designing your product with PA6. In fact, PA6.6 absorbs less humidity and is therefore inherently more stable. PA66 is used when PA6 reaches its temperature threshold or when the hydrolytic stability of PA6 is no longer sufficient. It has a good superficial appearance and is resistant to solder, resulting in a resistance to burst pressure.
PA6 and PA6.6 are mainly used in the automotive industry, electronics and the electrical sector. Due to its mechanical and thermal properties and resistance to oil and grease, polyamides are applied for electrical tool casing, pump casing, screws, gears, tanks, accessories, components in the engine compartment, fuel lines and fenders. In 90% of cases, all our PA6 or PA6.6 can be applied in all these fields in this specific sector.
