What is white masterbatch?
This material is a type of color masterbatch produced using titanium dioxide (TiO₂), a polymer base, and specific additives. This high-quality product is used to create a pure white color and enhanced transparency in plastic products, making it highly popular in various industries, including polymer films, injection molding, and other manufacturing processes.
In the production of white masterbatch, special additives are used that blend well with titanium pigment, providing long-lasting and uniform whiteness to products. Additionally, different types of this material are available with varying percentages of titanium dioxide, allowing for industrial applications based on specific needs.
Components of masterbatch
The composition of this material is a key factor in determining its final quality. The precise and balanced formulation of its components plays a significant role in white masterbatch and ensures uniform color distribution in plastic products. Its typical composition includes the following:
- Pigment: 40% to 80%, as the primary agent for creating the white color.
- Carrier resin: 15% to 20%, forming the structural base of the masterbatch.
- Dispersing agent: 5% to 10%, ensuring even distribution of pigments in the product.
- Processing aid: 0% to 5%, enhancing the production process and reducing costs.
- Thermal stabilizer: 0% to 2%, increasing the product’s resistance to heat.
- Filler: 0% to 40%, reducing production costs and improving mechanical properties.
Given the diverse applications of white masterbatch in various industries, the composition and percentages can be adjusted according to customer requirements to achieve optimal performance in the final product. This variation allows manufacturers to offer white masterbatches with different qualities suitable for a wide range of products.
Types of white masterbatch
These materials are categorized into two widely used types based on the amount of titanium dioxide and variations in color tone. The two main types include Refrigerator White Masterbatch and Pearlescent White Masterbatch, which are explained below:
Refrigerator White
This type, also known as Blue-White, has a high percentage of titanium dioxide (TiO₂), providing excellent white coverage. It is produced by adding TiO₂ to polymer bases such as polyethylene (PE), polystyrene (PS), and polyethylene terephthalate (PET). The titanium dioxide content in this product typically ranges from 30% to 75%, where an increase in TiO₂ enhances whiteness and brightness, directly affecting its price. Due to its easy production process and dust-free application, this type of masterbatch is highly popular.
Pearlescent White
Instead of conventional pigments, pearlescent masterbatch utilizes pearlescent compounds, giving products a glossy appearance and UV absorption properties. This feature enhances the surface brightness of products and protects them from sunlight. The pearlescent white masterbatch is widely used in packaging industries and products requiring a unique visual appeal, as it not only provides a white color but also adds aesthetic appeal and improved durability to the final product.
Advantages of white masterbatch
This material, utilizing titanium dioxide (TiO₂), imparts a white color, unique properties, high brightness, and transparency to polymer products. Here are some of its advantages that make its use essential in various industries:
- Uniform coverage
- UV resistance
- High light reflection
- Easy blending with polymers
- Weather resistance
- High thermal tolerance
- Enhanced appearance and brightness
The application of this material is crucial in various industries such as packaging, automotive, and electronics due to these features. It serves as an ideal solution for improving the color, durability, and other properties of polymer products.
Properties of white masterbatch
For the production of white masterbatch, varying percentages of titanium dioxide (typically between 10% to 75%) are added to the formulation. Rangin Polymer Company utilizes advanced techniques to adjust this percentage based on customer requirements. However, it should be noted that increasing the titanium content also raises the cost.
Key Properties of White Masterbatch:
- UV Absorption: Helps maintain product quality and durability against sunlight.
- High Transparency and Brightness: Ensures a glossy and shiny surface for final products.
- Uniform Coverage: Contributes to creating a smooth and even surface.
- Retention of Physical Properties: Enhances the durability and physical strength of the final product.
Due to these characteristics, white masterbatch is widely used in packaging, automotive, and household appliances industries, making it one of the essential raw materials in polymer product manufacturing.
Applications of white masterbatch
This type of masterbatch is produced by combining titanium dioxide with various polymer bases, providing white coloration and diverse physical properties to plastic products. Its main applications across different industries include:
Packaging Industry
White masterbatch is ideal for packaging due to its high coverage and light reflection properties, making it suitable for food products, cosmetics, personal care items, and detergents. It helps block UV light, ensuring the freshness and longevity of packaged goods.
Plastic Industry & Polyethylene Films
Used in polyethylene films, shopping bags, and disposable containers, white masterbatch enhances uniform coverage and aesthetics. The presence of titanium dioxide improves environmental resistance in these products.
Agricultural Industry
This material is utilized in agricultural products, such as silos and non-biodegradable mulch films, helping improve UV resistance and increasing durability.
