Understanding Aluminum Pellets: Composition and Structure

Aluminum pellets represent an advanced form of metallic pigments specifically engineered for plastic applications. Unlike traditional aluminum powders, pellets offer significant advantages in handling and performance.

Core Composition:

• High-purity aluminum powder: Primary coloring agent

• PE wax carrier: Ensures excellent dispersion and compatibility

• Specialized auxiliaries: Enhance processing and end-product properties

• High aluminum content: Delivers brilliant metallic effects

Key Characteristics and Advantages

Technical Features:

• Zero solvent content: Environmentally friendly formulation

• Low odor emission: Improved working conditions

• Dust-free operation: Enhanced workplace safety

• High thermal stability: Suitable for various processing methods

Performance Benefits:

• Excellent compatibility with multiple plastic systems

• Consistent color distribution

• Maintains polymer mechanical properties

• Easy handling and storage

Application Spectrum

Primary Industries:

• Automotive sector: Bumpers, trim components, interior parts

• Consumer electronics: Housings, decorative elements

• Home appliances: Casings, control panels, decorative trims

• General plastic products: Wherever metallic effects are desired

Compatible Plastic Systems:

• Polyethylene (PE)

• Polycarbonate (PC)

• Polypropylene (PP)

• ABS

• Polystyrene (PS)

Processing Guidelines

Optimal Usage Parameters:

Masterbatch Production:

• Recommended addition: 15-45%

• Low-speed mixing until uniform distribution

• Subsequent granulation for easy handling

Direct Injection Molding:

• Typical usage: 0.5-5%

• Direct addition to plastic granules or powder

• Thorough mixing before processing

Critical Processing Considerations

Storage and Handling:

• Store in sealed containers to prevent oxidation

• Maintain dry storage conditions

• Avoid prolonged exposure to air

Processing Precautions:

• Avoid high-speed shear: Preserves aluminum flake structure

• Control temperature: Prevents thermal degradation

• Prevent multiple processing cycles: Maintains metallic appearance

Quality Indicators:

• Proper processing: Bright metallic finish

• Over-processing: Blackened appearance, loss of metallic effect
