Patent product made from organosilicone by Shiru + Zairakka Co.
The patented products made from organosilicone by Sil + Zailah have internal and external lubricants that excel in high-temperature stability. Products that act as internal lubricants improve compound flow without affecting thermal aging properties in relation to polar polymers. On the other hand, external lubricant-type products form a boundary film between rubber and metal, providing a release effect while simultaneously reducing friction resistance between the two. Additionally, this same action helps suppress mold contamination. In other cases, applying them to highly filled cable formulations can improve extrudability.

Company information
We offer a wide range of German-made processing aids for rubber under the "Structol" brand, starting with lubricants. For many years, we have been favored by numerous rubber manufacturers in Japan, including the four major tire manufacturers, as well as many large, medium, and small companies. In recent times, with rising electricity costs and increasing raw material prices putting pressure on cost reduction, "Structol" contributes to reducing production costs for rubber product manufacturers by improving productivity, enhancing quality, and reducing defects.
