Kela New Materials specializes in Transparent sub-micron Cobalt Blue—a high-purity cobalt aluminate spinel (CoAl₂O₄, PB28) engineered for advanced industries where conventional cobalt blue pigments cannot meet performance requirements. With true sub-micron-scale particle control, exceptional thermal stability, and a clean, vivid cobalt-blue tone, our transparent cobalt blue delivers superior optical, thermal, and chemical performance across cutting-edge applications. At the heart of our material is an inverse spinel crystal structure that ensures: • Transparent or semi-transparent blue color in inks, coatings, ceramics, and glass • Exceptional heat resistance (up to 1000–1300°C) • High UV and weathering stability • Low ionic migration and ultra-low impurities • Excellent dispersion in polymers, inks, and ceramic matrices • Environmentally safe, non-toxic, non-leaching composition

钛铬棕具有金红石型结构耐温度高达1000℃，钛铬棕的黄相较为明显，所以其经常作为黄色颜料使用。钛铬棕中的铬和锑均已牢固地结合在二氧化钛的晶格结构上，无金属离子溶出，属于无毒环保颜料。遮盖力较好，但着色力稍差。颜料颗粒的硬度较大，研磨分散时需注意对介质材料的影响。耐光性，耐候性，耐温性及化学稳定性都很好，可用于对各项性能要求较高的涂料或塑料制品中。钛铬棕与大多数热固性和热塑性树脂相容。具有红外反射功能，可用于制作隔热涂料或作其它特殊用途。钛铬棕可看作是钛镍黄的类似产品，亦属于金红石晶格结构的一种颜料，因其用铬替代镍，所以产品呈棕色，故其性能同钛镍黄十分相似。 用途： 可用于卷钢涂料、粉末涂料、运输工具涂料、户外建筑涂料、伪装涂料、绘画涂料、路标涂料以及工程塑料，一般塑料，塑料玩具、食品包装塑料、印刷油墨、色母粒、高性能工业涂料、用于水泥，混凝土，屋面材料等建材，以及陶瓷等。

Kela Materials presents Copper Chrome Black Spinel (PBk28), a high-performance inorganic black pigment engineered for applications requiring extreme durability, thermal stability, and long-term weather resistance. Based on a copper–chromium spinel structure (CuCr₂O₄), PBk28 delivers deep black coloration with excellent resistance to UV, chemicals, and high processing temperatures. PBk28 contains only trivalent chromium (Cr³⁺) fully locked into a stable spinel lattice, with no hexavalent chromium (Cr(VI)) and no bleeding or migration in polymers. This makes it a safe, RoHS- and REACH-compliant solution for demanding plastics, coatings, ceramics, and construction materials.

PBK526 Eco Composite Functional Black is a composite inorganic black pigment developed by Kela Materials. It is primarily based on mixed oxides of copper (Cu), manganese (Mn), and iron (Fe), designed to deliver a purer, more stable black tone than many organic blacks or conventional carbon-based blacks in demanding processing environments.

This material is positioned for engineering use cases where thermal stability, process robustness, and color retention matter. PBK526 is not presented as a finished formulation; performance depends on binder/resin selection, dispersion method, film thickness, and processing temperature profile.

Typical value proposition: stable black appearance under heat and aging, with system-level predictability when carbon black introduces conductivity drift, blooming, or tone instability.
