What is I-MARV™?

I-MARV™ is Idemitsu's groundbreaking tackifier resin. It has proven excellent for hot-melt and pressure sensitive adhesives, and functions as a polyolefin resin modifier. I-MARV™ is extremely transparent, has excellent thermal stability and less odor. It also boasts excellent compatibility with base resins and elastomers.

Exclusively created based on polymerization and hydrogenation technologies developed by Idemitsu over decades of research. I-MARV™ displays a balanced performance in terms of heat and cold resistance as well as adhesive properties as a tackifier when used for a hot-melt adhesive. Especially I-MARV™ is highly recommended for hygiene and packaging hot-melt adhesive application.

I-MARV™ is available in partially hydrogenated S-grades and fully hydrogenated P-grades. Because they are broadly applicable, a wide selection of specific S- and P-grades are available to meet individual customer needs and applications.

We are operating two plants, the one is located in Tokuyama (Capacity: 10KT/Y) and the other is in Taiwan (Capacity: 25KT/Y). Our Taiwanese plant is operated by a joint venture between Idemitsu Kosan and Formosa Petrochemical Corporation. We continuously challenge to improve product quality as well as supply chain stability worldwide.

Furthermore, Tokuyama plant will be refurbished in 2022 with the aim of further lowering odor.
