Nylon,Polyamide PA6 Characteristics and Applications

Material Characteristics

Excellent mechanical properties

High strength and toughness: PA6 has better impact resistance and flexibility than PA66, making it suitable for dynamic loading scenarios (e.g. gears, sports equipment).

Wear resistance: low coefficient of friction makes it widely used in wear-resistant parts such as bearings and guide rails.

Thermal properties

Temperature resistance: Long-term use temperature 80~120℃, short-term up to 150℃ (lower than the temperature resistance of PA66).

Low melting point: about 220℃, low energy consumption during processing, suitable for filling complex molds.

Significant moisture absorption

High water absorption (about 3.5%), resulting in dimensional and performance changes, need to improve stability through modification (e.g. glass fiber reinforcement) or post-treatment (e.g. moisture adjustment).

Chemical stability

Resistant to oils and organic solvents, suitable for fuel lines, chemical plant components.

Weak acid and alkali sensitive: susceptible to strong acid and alkali corrosion, need to avoid contact.

Good processing performance

Good melt fluidity, suitable for injection molding, extrusion, blow molding and other processes, can make films, fibers (e.g. fishing line, fabrics).

High modification potential

Special needs can be met by adding glass fiber (to enhance strength), flame retardant (for electronic components), carbon fiber (to enhance electrical conductivity), etc.

Fields of application

Automotive industry

Critical parts: Engine hoods, radiator tanks (high temperature resistant), door handles (smooth surface).

Wear-resistant parts: Gears, bearings (e.g. wiper motor gears), utilizing their self-lubricating properties.

Electrical and electronics

Connectors and housings: Cell phone snaps, laptop hinges (need glass fiber reinforcement for dimensional stability).

Flame retardant applications: PA6 with added flame retardant for circuit breaker housings, UL94 compliant.

Consumer Goods

Tool handles: Drill housings are impact resistant and insulated for safety.

Sports equipment: Ski bindings, mountaineering buckles (lightweight and high strength).

Industrial equipment

Transmission parts: Conveyor belt chain guides (wear-resistant), industrial robot joint bushings.

Corrosion-resistant parts: chemical pump impellers (against weakly corrosive media).

Textile and Packaging

Functional fibers:Bulletproof vest fibers (high modulus modified PA6), high elasticity swimsuit fabrics.

Food packaging film: PA6/PE composite film for vacuum packaging, oxygen barrier for freshness.
