Improvement of flexibility and elasticity of vulcanized rubber products.
The role of plasticizers is to improve the flexibility and elasticity of vulcanized products. Their impact on processability is usually beneficial, but they are often used to enhance properties such as heat resistance and electrical conductivity in rubber products. Additionally, in high-filled filler formulations, they promote the dispersion of fillers.

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.
