Nylon(PA) Injection Molding: A Material Revolution in Motion

Nylon(PA) Overview: Origin, Properties, and Applications

Nylon is a synthetic polymer composed of polyamide (PA), first invented in 1935 by Wallace Carothers and his team at DuPont, and commercialized in 1938. It exhibits the following characteristics:

• High strength and toughness: With tensile strength reaching 75–85 MPa and elongation at break between 50–300%, nylon performs exceptionally well in high precision plastic parts and plastic injection molds factory applications.

• Excellent wear and fatigue resistance: Standard friction tests show a wear rate of less than 0.1 mg/N·m, and fatigue life can exceed 10^6 cycles, making it ideal for gears and rollers.

• Chemical resistance: Nylon shows less than 5% weight loss when exposed to common oils, phenols, and alcohols, meeting the strict requirements of medical injection molding for biomedical materials.

• Outstanding heat resistance and dimensional stability: With a heat deflection temperature of 100–120 °C and a thermal expansion coefficient of about 80×10^−6 /K, it maintains dimensional accuracy in high-temperature processes in plastic injection molds factory settings.
