Custom Color Masterbatch & Plastic Additives Manufacturer

MHK Color is a professional color masterbatch and functional plastic additives manufacturer based in Foshan, Guangdong, China. For more than 25 years, we have helped plastic processors, compounders, and brand owners across more than 60 countries achieve precise, consistent, and cost-effective coloring across virtually every polymer system, from commodity polyolefins to high-performance engineering plastics. Our facility integrates advanced twin-screw compounding lines, a dedicated color-matching laboratory, and spectrophotometric quality control, allowing us to move a project from an initial color specification to a production-ready masterbatch in as little as three days.

Behind every batch is a formulation database of more than 30,000 proven color recipes, maintained by 15 polymer engineers and 7 quality-control specialists. When you send us a target shade, our colorists select the closest reference and adjust pigment type, concentration, and carrier resin to match your polymer and process, returning a physical sample within 24 hours. We manufacture black masterbatch with 20% to 50% carbon black, white masterbatch with up to 75% TiO2, and custom color masterbatch in more than 30,000 Pantone, RAL, or sample-matched shades, alongside special-effect, functional additive, liquid color, and pre-dispersed pigment masterbatches.

Our masterbatches serve nine core industries, from food-contact packaging and automotive interiors to agricultural films, medical devices, construction, electronics, textiles, consumer goods, and 3D printing. We verify color on every batch by spectrophotometry, holding batch-to-batch consistency within Delta E below 1.0 under an ISO 9001 quality system. We provide complete documentation including CoA, TDS, SDS, and REACH and RoHS declarations, plus FDA and EU 10/2011 compliant formulations for regulated applications, so you can be confident in quality and compliance at every shipment.

Working with us is fast, transparent, and low-risk. Share your resin, target shade, and performance requirements, and our technical team responds within three hours with a recommendation and quotation, then produces a free sample within 24 hours for standard formulations. Once approved, we scale to production from a 25 kg minimum order, supporting everything from small-batch trials to multi-ton contracts with consistent, documented quality. We are equally committed to sustainability, offering PCR and bio-based carrier masterbatches, NIR-detectable black for fully recyclable packaging, and low-VOC metallic effects.
