It provides excellent flow improvement and slip effects to highly polar special polymers.
The group of products based on Structol's fatty acid esters consists of multifunctional lubricants. They are primarily used with highly polar polymers and provide excellent flow improvement and lubricating effects regardless of the type of filler. Due to their appropriate polarity, they demonstrate particularly superior overall performance with specialty polymers such as NBR, HNBR, ACM, and EAM even at low additive levels. Structol WB212 can be noted as a very efficient dispersant for white active 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.
