Pigments and additives for plastics manufacturing

Our pigments for chemical applications

Plastics require pigments that can withstand heat, UV exposure, and chemical contact without compromising performance. At James M Brown, we supply:

• Cadmium pigments: Used in high-spec polymers and engineering plastics, cadmium pigments offer unparalleled thermal stability, weather resistance, and vibrant colour—particularly in red, orange, and yellow tones. As a REACH-compliant manufacturer, we ensure full safety and traceability in all industrial applications.
• Anti-corrosive pigments: Formulated into protective plastic coatings and extruded profiles for harsh environments, our anti-corrosive pigments provide long-lasting protection against oxidation and corrosion.
• Zinc oxide: A multifunctional pigment for plastics, zinc oxide enhances UV resistance, thermal performance, and antimicrobial properties. Used in outdoor applications, medical plastics, and rubber-modified compounds.
• Inorganic pigments: From iron oxides to titanium dioxide and zinc compounds, our inorganic pigments offer durable, non-fading colouration for PVC, polyolefins, and engineering polymers, delivering excellent opacity, dispersion, and long-term performance.

Our additives for for plastic compounding

Additives are critical to achieving desired processing characteristics and performance in plastic products. Our tailored additive solutions include:

Defoamers: Prevent air entrainment during compounding and extrusion, improving surface finish and consistency in plastic parts.

Wetting agents: Improve adhesion between pigments and polymer matrices, ensuring better compatibility and process stability.

Dispersing agents: Facilitate uniform pigment distribution in the melt phase, enhancing colour strength, consistency, and optical properties.

Antioxidants: Protect polymer chains from oxidative degradation during processing and end-use, improving thermal resistance and product life.

UV stabilisers: Guard against UV-induced degradation, fading, and chalking—essential for outdoor plastics, automotive components, and packaging.

Detailed applications

Our pigment and additive technologies are trusted across a wide range of plastic applications, including:

• Thermoplastic compounding: Masterbatch and direct pigmenting for PE, PP, PVC, PS, ABS, and more.
• Engineering polymers: High-performance pigments for PA, PBT, PC, and PEEK applications.
• Plastic coatings: Colourants and UV stabilisers for dipped, sprayed, and extruded coatings.
• Packaging materials: Food-contact safe pigments and additives for durable, colour-accurate packaging.
• Construction plastics: Pipes, panels, profiles, and fittings with stable, weather-resistant pigmentation.
• Consumer products: Colour-matched plastics for appliances, electronics, and home goods.
