At K 2025, Sun Chemical will present its extensive color materials and high-performance polyphenylene sulfide (PPS) portfolio.

Sun Chemical will show colorants for engineering plastics and PPS solutions for multiple applications.

It comprehensive lineup of innovations for plastics coloration and functional effects includes new pigment launches, advanced effect finishes, fiber and e-mobility color solutions. In addition, the company will also present PPS engineering compounds, highlighting PPS grades designed for applications from automotive e-powertrains to drinking water systems.

Color materials for plastic applications

At the K fair, Sun Chemical will highlight the launch of FASTOGEN Super Red BBF, a transparent blue-shade red pigment suitable for sensitive applications and delivering high saturation with low haze, excellent dispersibility, strong heat resistance and minimal warping in HDPE injection-molding.

Also on display will be functional black pigments for heat and NIR light management, including Sun Chemical’s newest black pigment, Spectrasense Black 0089 FK, which offers high jetness in full shade, high NIR transparency, excellent heat stability and reliable outdoor performance, making it ideal for solar heat control in building and automotive applications, laser welding and LiDAR-detectable parts.

For fiber applications, Sun Chemical will highlight its broad portfolio of solutions, including ECO PASSPORT by OEKO-TEX-certified products for PP, PES and PA fibers. The newly launched FASTOGEN Pink K 4430 FP colorant offers exceptional dispersibility and a low filter-pressure value, suitable for the most demanding fiber applications.

Sun Chemical’s pigment preparations, such as Microlen, Eupolen PE NQ, Micranyl and Microlith, enable efficient mass coloration of PVC, polyolefins, rubber and engineering plastics. Eupolen PE combines high pigment load with superior dispersion, reduced warping and broad compliance, making it ideal for caps, closures, crates and containers.

Effect pigments on display will range from high-chroma micas such as Lumina, to Benda-Lutz aluminum pigments, which provide metallic sparkle in premium COMPAL grades and GOLDBRONZE powders.

Heliogen Phthalocyanine pigments, produced using a unique process, offer the highest purity in the market, making them ideal for sensitive uses, such as food packaging and toys, while meeting strict EU Article 3 compliance standards.

PPS compound innovations

Key PPS solutions on display at K 2025 will include:

• Unfilled Extrusion Grade (DIC.PPS Z-200-XP BLACK): A high-viscosity, impact-modified PPS designed for automotive coolant pipes, combining flexibility with inherent chemical and heat resistance.

• Bus Bar Applications (DIC.PPS Z-240 BLACK): Engineered for hybrid/electric vehicles, this grade offers high flowability, heat shock resistance minimal dimensional variance, and high dielectric strength.

• Drinking Water Applications (DIC.PPS Z-230 BLACK): These solutions maintain key approvals with excellent dimensional stability, hydrolysis resistance and weldability.

• Metal Plating Grade (DIC.PPS MP-6060 BLACK): This grade can be etched in standard baths, while retaining PPS’s inherent properties, providing aluminum-level electric shielding and supporting lightweight, high-precision injection-molded designs.

• Thermally Conductive Series (DIC.PPS TX-Series): Electrically insulative yet thermally conductive, this thermal series is designed to lower coil surface temperature in electric engines while maintaining mechanical strength and processability.
