White Masterbatches

White masterbatches are a type of additive masterbatch specifically designed to impart a bright white color to plastic products. They are composed of a carrier resin and white pigments.

Key Characteristics of White Masterbatches

• Brightness: Provide a high level of whiteness and opacity to plastic materials.
• Uniformity: Ensure consistent color throughout the plastic product.
• Durability: Maintain their color over time, even when exposed to UV radiation or other environmental factors.
• Versatility: Compatible with a wide range of base polymers, including polyethylene, polypropylene, polystyrene, and more.

Applications of White Masterbatches

• Injectable parts
• Bottles
• One layer and three-layer films
• Production of yarn and polymer bags
• PE and PP base pipes
• Disposable containers based on PP – PS – HIPS

Types of White Masterbatches

• TiO2-Based White Masterbatches: Use titanium dioxide (TiO2) as the primary pigment, offering excellent whiteness and opacity.
• Zinc Oxide-Based White Masterbatches: Use zinc oxide as the pigment, providing good whiteness and UV protection.
• Carbon Black-Based White Masterbatches: Use carbon black in combination with other pigments to achieve a bright white color with enhanced opacity.

Factors to Consider When Choosing White Masterbatches

• Whiteness level: The desired level of brightness and opacity.
• Base polymer compatibility: Ensure compatibility with the base polymer being used.
• UV resistance: If the plastic product will be exposed to sunlight, select a white masterbatch with good UV resistance.
• Cost: Consider the cost of the white masterbatch and the overall cost of the final product.

By using white masterbatches, manufacturers can achieve a bright, clean, and professional appearance for their plastic products.
