Wear Resistant Extruded Nylon PA6 Plastic Rod
Product performance of pa6 nylon
Mechanical properties
High rigidity: tensile strength 50-80MPa (unreinforced), flexural modulus 2000-3000MPa; after glass fiber reinforcement (such as GF30%), the tensile strength can be increased to 100-150MPa, and the flexural modulus can reach 5000-8000MPa, which is close to the strength level of some aluminum alloys (such as 6061-T6 aluminum alloy tensile strength of about 310MPa), suitable for structural parts with high static loads.
High impact resistance: cantilever beam notch impact strength ≥5-15kJ/m² (normal temperature), can still maintain good toughness (brittle temperature about -40℃) at low temperature (-20℃), better than HIPS (high impact polystyrene), can withstand dynamic loads or accidental impacts without breaking easily.
Fatigue resistance: The performance decays slowly under repeated loads (such as dynamic support parts), and the surface hardness (Rockwell R-scale) is about 110-120, which is better than ABS and HDPE, and is suitable for scenes with long-term cyclic stress.
Thermal properties
High temperature resistance: The melting point is about 215-225℃, and the heat deformation temperature (under 1.82MPa load) is about 60-80℃ (unreinforced). After glass fiber reinforcement (such as GF30%), it can be increased to 150-180℃. The long-term use temperature range is -40℃ to 120℃ (short-term tolerance of 150℃), which is suitable for structural parts in high temperature environments.
Low thermal expansion coefficient: about 8-10×10⁻⁵/℃, the dimensional stability is better than ordinary plastics (such as PP, PVC), the deformation is small under temperature fluctuations, and it is suitable for precision parts manufacturing.
Chemical properties
Chemical corrosion resistance: Stable to weak acids (such as acetic acid), weak bases (such as sodium carbonate) and some organic solvents (such as ethanol, lubricating oil), but long-term contact with strong oxidants (such as concentrated nitric acid), halogenated hydrocarbons (such as carbon tetrachloride) or aromatic hydrocarbons (such as toluene) may cause swelling or stress cracking; good tolerance to water, steam and alkaline media, suitable for chemical storage tanks, food processing equipment and other scenarios.
Water absorption: The equilibrium water absorption rate is about 3%-4% (unenhanced), and the dimensional stability decreases slightly after water absorption, but the impact strength will increase due to water absorption (pay attention to drying before processing, the water content must be <0.2%).
Electrical properties
Insulation: Volume resistivity ≥10¹³Ω·cm, dielectric strength 15-25kV/mm, it is a good insulating material, suitable for low-voltage electrical components; but the dielectric constant and loss factor increase after moisture absorption, which is not suitable for high-frequency insulation scenarios.
Processing performance
Easy to process: Complex shapes can be manufactured through thermoforming (such as vacuum forming), mechanical processing (such as cutting, drilling, turning), injection molding and welding (such as ultrasonic welding, hot plate welding); low water absorption (need to dry to moisture content <0.2% before processing, drying temperature 80-90℃), high dimensional stability after processing.
Surface treatment: The surface can be printed, sprayed or electroplated, suitable for application scenarios with high decorative requirements (such as home appliance housings, automotive parts).
Other characteristics
Density: About 1.10-1.15g/cm³, only 1/7 of steel and 1/4 of aluminum, suitable for lightweight applications.
Self-lubricating: The friction coefficient is 0.15-0.3, which is better than most engineering plastics (such as POM, PP), suitable for low-friction moving parts (such as gears, bearings).
Weather resistance: PA6 rods without stabilizers may turn yellow and become brittle after long-term outdoor exposure. UV stabilized products (such as adding carbon black or hindered amine light stabilizers) need to be selected.
Product advantages
Combination of high strength and light weight
The tensile strength and bending modulus of PA6 rods are significantly higher than those of general plastics such as HDPE and PP, and are close to the level of metal materials, but the density is only 1/7 of steel and 1/4 of aluminum. In the fields of automobiles and machinery, it can replace aluminum alloy or zinc alloy to manufacture structural parts, reduce weight by 30%-50%, and significantly reduce energy consumption (for example, reducing the weight of automobile parts can improve fuel efficiency by 5%-8%).
Excellent wear resistance and self-lubrication
The friction coefficient of PA6 rods is low (0.15-0.3), and the wear rate is less than 0.1cm³/(N·m), which is much better than POM (polyoxymethylene) and PP (polypropylene). In high-friction scenarios such as conveyor belt guides and machine tool sliders, long-term stable operation can be achieved without additional lubrication, reducing maintenance frequency (for example, the life of mining machinery linings is increased by 3-5 times).
High temperature and fatigue resistance
PA6 rods have better heat deformation temperature (up to 180°C after glass fiber reinforcement) and long-term use temperature (-40°C to 120°C) than most general-purpose plastics (such as PVC, LDPE). They can maintain stable performance in high-temperature engine compartments, steam environments or repeated loads, and are suitable for dynamic application scenarios (such as parts around automobile engines).
Processing economy and environmental protection
PA6 rods can be efficiently molded into complex shapes through injection molding and extrusion, with high material utilization (waste can be 100% recycled); processing equipment is highly versatile (sharing molds with engineering plastics such as PA66), and production costs are 40%-60% lower than metals or high-performance engineering plastics (such as PEEK), which is in line with the concept of sustainable manufacturing.
