Polymer Consideration

Polymer 1

When several types of polymers are required in the assembly of a component, achieving a consistent and accurate colour match across the range of polymers is important to create a unified brand identity and meet the expectations of the end buyer.

In addition to these considerations mentioned, achieving a consistent colour match across different polymers requires expertise in colour matching, knowledge of the specific properties of each polymer, and an understanding of how the different polymers will interact with each other during processing and assembly.

The masterbatch supplier's technical knowledge and experience in working with various polymers can be crucial in achieving a consistent colour match across different polymers. The supplier can provide guidance on the selection of the appropriate masterbatch, colour matching techniques, and processing conditions to achieve the desired result.

It is important to work closely with the masterbatch supplier to develop a customized solution that meets the specific requirements of the application and achieves a consistent and accurate colour match across the range of polymers used in the assembly of the component.

At Colourhouse, we are experts when it comes to colour matching across several polymer to provide a consistent and uniformed product without compromising on aesthetics or functionality.

Generally, Polymer specific masterbatch are formulated for use with a specific grade of polymer, so, what happens if you want to use this Masterbatch in a different grade to the polymer specified.

Using a polymer-specific masterbatch with a different grade of polymer than the one specified can lead to unpredictable results and may not achieve the desired performance or appearance characteristics.

Polymer-specific masterbatches are formulated to work optimally with the particular grade of polymer they are designed for. They are usually tailored to address specific performance requirements such as colour, UV stability, flame retardancy, and other properties.

If you use a masterbatch intended for one polymer with a different polymer, it can cause issues such as poor dispersion of the colorants, inadequate performance in the final product, and incompatibility between the masterbatch and the polymer. This can lead to defects in the finished product, such as colour variations, lamination, inconsistent properties, or even structural failures.

Therefore, it is essential to use a masterbatch specifically formulated for the polymer grade you are using to ensure optimal performance and avoid issues in the final product. If you want to use a masterbatch with a different grade of polymer, you should consult with the manufacturer of the masterbatch and the polymer to determine if it is suitable for the intended application.

In the image below you can see 4 different Grades of ABS polymer, we moulded the same Blue Masterbatch at the same addition rate, in three of these polymers and achieved similar shades to the illustration shown below.

But, If a masterbatch has been formulated for use with a specific polymer grade, it may be compatible for use in another like-for-like grade of polymer, that doesn't imply that you will receive the same colour or opacity in the final mould, it is important to confirm this with the masterbatch supplier before use.

Even similar polymers provided by different companies or in different regions of the world can vary in base colour, and this can affect the final appearance of the product when using a colour masterbatch.

The base colour of a polymer can be influenced by various factors such as the type of raw materials used, processing conditions, additives, and environmental factors such as exposure to sunlight or heat. These factors can lead to variations in the polymer's colour, shade, and tone, even if the polymers are technically the same.

Therefore, when using a colour masterbatch, it is important to test the masterbatch with the specific polymer you are using to ensure that the desired colour and appearance are achieved. It may also be necessary to adjust the colour masterbatch formulation or processing conditions to achieve the desired results.

Moreover, it is important to note that different regions of the world may have different regulatory requirements or standards for polymers which can also affect the availability and performance in those regions. Therefore, it is advisable to consult with the manufacturer of the masterbatch and the polymer to ensure that the masterbatch is suitable for use with the specific polymer grade and meets the relevant regulatory requirements for the intended application.
