Color Masterbatch

Yes. We can develop color masterbatch based on Pantone references, RAL colors, or customer-provided physical samples. For applications with higher color accuracy requirements, we recommend providing an actual molded part, film, sheet, color chip, or finished-product sample whenever possible. Please note that the final color appearance can be affected by the base polymer, product thickness, surface finish, processing method, and masterbatch dosage. Final approval should therefore be based on testing under the customer's actual processing conditions.

To recommend or develop a suitable grade, we usually need the base polymer, the target color or a physical sample, the processing method, the product or wall thickness, the surface requirement (glossy, matte, opaque, translucent or transparent), the expected masterbatch dosage if available, the end-use application, any special performance requirements, and the estimated order quantity. The more complete the application information is, the more accurately we can evaluate the formulation and recommend a suitable solution.

Not always. If the project only requires matching a standard Pantone or RAL color, we can start with the color reference. However, a physical sample is strongly recommended when matching an existing finished product, a special or custom shade, a translucent or transparent color, a metallic, pearl or special-effect color, or a product whose appearance is strongly affected by thickness or surface texture. For final confirmation, testing with the customer's actual resin and processing conditions is recommended.

Color masterbatch can be developed for common thermoplastics such as PE, PP and EVA, as well as selected engineering plastics including ABS, PS, SAN, PC and PA, depending on the application and formulation. The carrier resin must be selected carefully because compatibility can affect color dispersion, processing stability, surface appearance, mechanical properties, and migration or blooming risk. For this reason, we recommend confirming the exact polymer grade before finalizing the masterbatch formulation.

Color consistency depends on both formulation control and production consistency. For customized color projects, color matching can be evaluated using standard color references, retained samples, and instrument-based color comparison where applicable. We also recommend confirming key application conditions such as base resin, addition rate, product thickness, processing temperature and surface finish. For repeat orders, keeping these conditions consistent helps reduce visible color variation between production batches.

There is no single dosage that is suitable for every application. The recommended addition rate depends on the target color strength, base resin color, product thickness, opacity requirement, processing method and required surface appearance. For many applications, the dosage is determined during sample testing rather than by a fixed standard value. We can recommend a starting dosage based on your application and adjust it according to the test result.

Yes, depending on the polymer and end-use requirements. Special color effects may include transparent or translucent colors, pearl effects, metallic effects, fluorescent colors, marble or flow-pattern effects, and custom appearance combinations. These effects are generally more sensitive to material compatibility, product thickness, processing conditions and mold design, so sample evaluation is recommended before mass production.

This can happen even when the masterbatch itself is consistent. Common causes include different base resin grades, changes in masterbatch dosage, different product thickness, processing temperature variation, residence time differences, surface texture or gloss differences, uneven dispersion, and moisture or contamination. If a color difference appears during production, we recommend comparing the actual processing conditions first. We can also assist with troubleshooting based on the resin, dosage, process parameters and product samples.
