ABS+PA Alloy Material Solution

—— The Perfect Fusion of Strength & Toughness

Key Advantages

High Strength + High Toughness – Combines PA’s rigidity with ABS’s impact resistance for superior mechanical performance.

Enhanced Heat Resistance – 20-30°C higher HDT (Heat Deflection Temperature) vs. pure ABS.

Excellent Processability – Retains ABS’s easy molding properties while reducing PA’s processing challenges.

Cost-Effective – More affordable than pure PA, yet outperforms standard ABS.

Performance Comparison

Property ABS PA6/PA66     ABS+PA Alloy

Tensile Strength (MPa)      40-50    70-85    55-75

Impact Strength (kJ/m²)    20-30    5-15      15-25

HDT (°C) 85-100  180-220 110-150

Molding Shrinkage (%) 0.5-0.7   1.0-1.5   0.6-1.0

Recommended Formulation

Base Formula (Customizable):

ABS: 50-70%

PA6/PA66: 30-50%

Compatibilizer (e.g., ABS-g-MAH): 3-8%

Lubricant (Zinc Stearate/EBS): 0.2-0.5%

Antioxidant (1010/168): 0.1-0.3%

Customization Options:

Reinforced Version: Add 15-30% glass fiber (↑ stiffness, HDT >160°C).

Flame-Retardant: Add brominated/phosphorus FR agents (UL94 V-0 achievable).

Wear-Resistant: Add PTFE/graphite (↓ friction coefficient by 30%+).

Processing Guidelines

Pre-Drying:

ABS: 80°C × 2h

PA: 100°C × 4h

Twin-Screw Compounding:

Temp: 200-240°C (PA6) / 240-260°C (PA66)

Screw Speed: 300-400 rpm

Injection Molding:

Mold Temp: 60-80°C

Injection Pressure: 60-80 MPa

Typical Applications

Automotive: Dashboard frames, door handles, cooling fans (heat + impact resistance).

Electronics: Socket housings, router casings (flame retardancy + dimensional stability).

Tools & Equipment: Power tool housings, gears (wear resistance + high strength).

Sports Gear: Ski bindings, helmet components (lightweight + toughness).

Critical Notes

Compatibilizer Required: Must use (e.g., maleic anhydride grafted polymer) to prevent delamination.

Moisture Control: PA must be thoroughly dried to avoid bubbles/strength loss.

Temperature Window: Processing temp must exceed PA’s melt point but stay below ABS’s degradation threshold.
