PA6 is a milky white or faintly yellow transparent to opaque, crystalline polymer with good colorability, toughness, wear resistance, self-lubrication, low rigidity,低温 resistance, resistance to bacteria, and slow combustion; it extinguishes slowly after being removed from the flame, exhibiting dripping and foaming phenomena. Its molding and processing capabilities include injection molding, blow molding, casting, spraying, powder molding, machining, welding, and bonding. PA6 has a higher water absorption rate and poor dimensional stability, which affects its electrical properties (breakdown voltage). The service temperature of PA6 can reach 180°C, but it can be reduced to 160°C by adding impact modifiers. With 15%-50% glass fiber reinforcement, it can be increased to 199°C, and inorganic filled PA6 can further enhance its heat deflection temperature.
