Definition of High Temperature Nylon
High-temperature nylon (HTPA) is a heat-resistant polyamide, an engineering plastic suitable for long-term use in environments at 150°C. It exhibits excellent performance in heat resistance, electrical properties, physical characteristics, and chemical resistance. Notably, it maintains high rigidity and high strength even at elevated temperatures, along with excellent dimensional accuracy and stability.
High Temperature Nylon Properties
High temperature performance: Heat deflection temperature of 280°C (at 1.8 MPa) and continuous use temperature of 180°C.
Creep performance: The high crystallinity of HTPA allows it to retain excellent rigidity at high temperatures (above 120°C), offering aluminum-like strength, steel-like hardness, and rubber-like flexibility, ductility, and impact resistance.
Excellent dimensional accuracy and stability: The molecular structure of HTPA contains aromatic rings in its chain, making the molecular structure more regular and the chain less prone to movement.
Chemical resistance: Polyamide materials generally exhibit good resistance to most chemicals. Like other polyamide materials, HTPA is no exception, showing particularly good resistance to oils and greases at high temperatures.
Hygroscopicity: HTPA fiber-reinforced products have low moisture absorption, absorbing only half as much water as the same amount of glass fiber reinforced PA46 products. This low moisture absorption saves customers drying costs and results in better dimensional stability of the product.
Toughness: The excellent impact toughness of HTPA makes it the material of choice for demanding production applications.
