DIA 25mm Polyamide PA6 Plastic Bar PA6 Rod
PA6 Rod (Polyamide 6 Rod) is a solid, cylindrical thermoplastic engineering plastic rod made from nylon 6 (polycaprolactam) resin via an extrusion process. As one of the most widely used nylon grades, PA6 Rod combines high strength, high wear resistance, excellent processing flexibility, and reasonable cost advantages. It is an ideal alternative to metals (such as steel and copper) or traditional engineering plastics (such as POM) in machinery manufacturing, the automotive industry, and electronic and electrical industries. It is particularly suitable for rotating, transmission, or support components that require wear resistance, corrosion resistance, and self-lubrication.
Core Features
Excellent Mechanical Properties
High Strength and Rigidity: Tensile strength reaches 60-90 MPa (depending on diameter and formulation), with high flexural strength. It can withstand moderate to high loads (such as dynamic rotation or static support conditions), making it suitable for components requiring structural strength, such as gears, bushings, and guide rails.
Excellent Toughness: Its impact strength exceeds that of most general-purpose plastics (such as PVC and ABS), and it resists brittle cracking at room and low temperatures (above -20°C) (extending to -40°C after toughening modification).
Outstanding Wear Resistance: Its surface hardness is moderate (Rockwell hardness R100-115), its coefficient of friction is low (approximately 0.15-0.3), and its self-lubricating properties (similar to those of "plastic bearings") ensure it resists wear over time, with a service life far exceeding that of metal or ordinary plastics.
Flexible Processing Performance
Easy Cutting and Secondary Processing: PA6 nylon rod can be precisely formed using conventional machining methods such as turning, drilling, milling, and tapping, achieving processing efficiency comparable to that of metals (such as aluminum) without requiring complex heat treatment. It can also be cut to any length to meet customized requirements.
Stable Extrusion: The continuous extrusion process allows the production of pa6 nylon rods in a wide range of diameters (1-200mm) and lengths (typically cut to length according to customer specifications). It features a smooth surface (Ra ≤ 0.8μm) and high dimensional accuracy (tolerance ±0.1-0.3mm).
Chemical Resistance and Environmental Adaptability
Chemical Corrosion Resistance: It exhibits excellent resistance to weak acids (such as dilute sulfuric acid and acetic acid), weak bases (such as dilute sodium hydroxide solution), saline solutions (such as sodium chloride), and common organic solvents (such as ethanol and gasoline), making it suitable for applications involving non-severely corrosive media. However, prolonged exposure to strong acids (such as concentrated sulfuric acid), strong oxidizers (such as concentrated nitric acid), or aromatic hydrocarbons (such as benzene) may cause swelling or degradation. Clear temperature resistance range:
Long-term operating temperature: -40°C to 80°C (conventional unfilled PA6);
Short-term peak withstand temperature: Up to 120°C (if exposed to short-term heat);
Low-temperature performance: Toughness decreases below -20°C (extends to -40°C after toughening modification).
Medium weather resistance: Long-term exposure to UV rays (outdoor environments) can cause molecular chain breakage, yellowing, and embrittlement (this can be improved by adding UV inhibitors; protective coating is recommended for outdoor use).
Electrical properties
Excellent electrical insulation: Volume resistivity > 10¹⁴ Ω·cm, high dielectric strength (approximately 20-30 kV/mm), suitable for insulating components in low-voltage electrical equipment (such as switch brackets and terminal blocks).
Usage Precautions
1. Impact of Water Absorption: PA6 readily absorbs water (saturated water absorption rate approximately 3%-5%). This causes dimensional expansion (linear expansion coefficient approximately 1×10⁻⁴/°C), resulting in a slight decrease in strength and stiffness. Drying (drying at 80-100°C for 2-4 hours) before use is recommended to control the moisture content to <0.2%. Dimensional compensation should be considered for use in long-term humid environments.
2. Processing Compatibility: During processing, avoid prolonged high temperatures (>250°C) to prevent decomposition (producing irritating gases). The recommended extrusion temperature is 220-260°C. Use carbide tools for turning/drilling and ensure adequate cooling.
3. Environmental Protection: For outdoor use, add a UV inhibitor or apply a protective layer (such as a coating or lamination) to the surface to prevent aging and yellowing. For high-load applications, select reinforced (such as GF30%) or wear-resistant (MoS₂-added) rods.
