Kisuma Chemicals B.V.

We are the market-leading global supplier of synthetic layered double hydroxides (generally referred to as "hydrotalcites"​) for plastics. With our other product, synthetic magnesium hydroxide, we focus on specialty applications in niche markets. In 1966, our parent company Kyowa Chemical Industry (Japan) was the first in the world to succeed in the industrial synthesis of hydrotalcite. This product, an environmentally friendly layered-double-hydroxide (LDH), was first introduced as an antacid for the pharmaceutical industry. Before long, hydrotalcite found its way to a broad range of applications, which benefit from its reliable and triggered-response mechanism of scavenging acids. Examples of these applications include:• PVC: Non-toxic heat stabilizers.• POLYOLEFINS: Scavenger of acidic residues from catalysts (e.g. Ziegler-Natta).• HALOGENATED FLAME RETARDANTS: Scavenging free halogen ions.• COATINGS & ADHESIVES: Corrosion inhibitor.In 1997, Kisuma Chemicals BV was incorporated to service markets in Europe, the Americas, Africa and the Middle East. In Veendam (the Netherlands), we operate the world's largest, state-of-the-art factory in its kind. In Veendam, a source of magnesium chloride (our key raw material) with exceptional purity is present. This combined with our proprietary technology results in products with the highest available quality. Moreover, our products are available: Any Time - Any Place - Any Quantity.
