masterbatch and plastic customer how to choose silver metallic Pigment
The choice of aluminum pigments in plastic masterbatches and plastics should be based on the finished product type, performance requirements, and cost considerations.
Firstly , choose by Product Type
Silver color masterbatch for film: Focusing on hiding power, aluminum paste or aluminum powder is recommended. Aluminum powder is preferred for high-end products (high hiding power and smooth effects), while aluminum paste can be used for low-end products , give cost effective for basic requirement in agriculture film and shopping bags, envelope etc .
injection molding masterbatch: Aluminum paste can be used for standard silver-gray colors. For odorlessness or special functional properties ,such as hardness or heat resistance, aluminum powder is used. We also recommend Aluminium pellets for injection molding masterbatch , give high solid contents, easy dispersion and less solvent and odor , that suits for high end products such us automatic spare parts, ABS engineering plastics , accessories of home appliance etc. The advantages of Aluminum pellets for instance , easy dispersion , compatible with other inorganic pigments and safety transportation .
Spray-free products: Aluminum paste is often used for shimmering effects or electroplating-like effects, but the effects of solvents on plastic properties should be considered.
Choose by Functional Requirements
Color Effect: Aluminum paste is suitable for standard silver-gray tones, while aluminum powder can achieve a more delicate silver effect.
Functional Requirements: Aluminum powder is preferred for odorlessness. For high heat resistance requirements (>180°C), the stability of the aluminum pigment must be ensured.
Aluminum pigment particle size affects performance: Small-particle aluminum powder offers superior hiding power but price is expensive, while large-particle aluminum powder is suitable for general needs.
Solvent compatibility: For spray-free products, ensure the compatibility of the solvent with the plastic substrate to avoid performance degradation.
