PA12 (Nylon 12) Product Information

Material Overview

PA12 is the most widely used long carbon chain nylon. It offers a balanced combination of mechanical strength, chemical resistance, and lightweight performance.

Compared with PA11, PA12 uses butadiene as raw material, which is more cost-efficient and enables broader industrial applications.

Key Properties

• Low water absorption (excellent dimensional stability)
• Low density among engineering plastics
• Good impact resistance and flexibility
• Excellent low-temperature performance (-70°C brittleness resistance)
• Fuel, oil, and chemical resistance
• Excellent electrical insulation properties
• Good wear and low friction performance

Detailed Performance

1. Density

PA12 has a density of only 1.01–1.03 g/cm³, making it one of the lightest engineering plastics.

2. Melting Point

Melting range: 172–178°C, suitable for automotive and industrial applications.

3. Water Absorption

Lowest water absorption among nylon materials, ensuring excellent dimensional stability.

4. Impact Strength

No fracture at -20°C and -40°C testing, suitable for harsh environments.

5. Low Temperature Resistance

Maintains performance down to -70°C, ideal for cold climate applications.

6. Fuel & Chemical Resistance

Resistant to fuels, oils, alcohols, and automotive fluids, making it suitable for fuel system components.

7. Electrical Performance

Excellent dielectric properties even in humid environments due to low water absorption.

Applications

Automotive

Used in fuel lines, brake hoses, vacuum lines, battery cooling systems, and fluid transport systems.

Pipes & Cables

Used in offshore pipelines, gas lines, protective coatings, and communication cables in extreme environments.

3D Printing

PA12 powder is widely used in SLS 3D printing due to high flowability and dimensional accuracy.

Medical

Used in catheters and medical tubing due to biocompatibility and flexibility.

Consumer Products

Used in eyewear frames and daily consumer components requiring flexibility and fatigue resistance.

Coatings & Adhesives

Used for anti-corrosion coatings on metals and industrial protective layers.
