PA12 (Polyamide 12), commonly known as Nylon 12, is distinguished by its exceptionally low moisture absorption. While PA6 absorbs up to 9% and PA66 absorbs 8-9% moisture at saturation, PA12 absorbs only 0.9% maximum—making it the premier choice for applications requiring dimensional stability in humid, wet, or underwater environments.
Key Properties of PA12
PA12’s moisture absorption is only 0.9% maximum (10x lower than PA6/PA66), with melting point of 178-180°C and continuous service temperature up to 130°C short-term. Impact strength reaches 30-40 kJ/m² retaining toughness at -40°C. Chemical resistance is excellent against fuels, oils, and brake fluids. Our PA12-CF30 provides enhanced mechanical properties.
アプリケーション
PA12 is used in automotive fuel systems (SAE J844, ISO 13775 compliant), marine hardware and underwater cables, pneumatic systems, medical devices, and cryogenic applications.
