Adhesive base material
Adhesive base materials are raw materials for adhesives and adhesives used to fix and bond parts together.
"Hydroxyl Terminated Poly butadiene™" is a liquid polymer with a highly reactive hydroxyl group at the end of the molecule.
Like general polyols, which are raw materials for polyurethane, it is easily cured by reaction with various isocyanate compounds and becomes a high-quality urethane elastomer (rubber elastic body).
In addition, we also have the polyisoprene type "Hydroxyl terminated liquid Poly isoprene™" and the polyolefin type (hydrogenated type) "Hydroxyl terminated liquid Poly olefin™". All grades do not contain easily hydrolyzable groups in their main chain structure, making it possible to design materials with excellent hydrolysis resistance.
In addition, "I-MARV™" (I-MARV: hydrogenated petroleum resin) is a colorless and transparent petroleum resin originally developed based on the polymerization and hydrogenation technology that Idemitsu Kosan has cultivated over many years.
When I-MARV is used as a hot melt adhesive (HMA), it exhibits a balanced performance in heat resistance, cold resistance, and adhesion. In addition, I-MARV can be added to BOPP film* to improve transparency, rigidity, and water vapor barrier.
