B Series / 1,2-Polybutadiene Homopolymer
The B Series is a homopolymer of butadiene. It has excellent plasticity as a property-modifying additive for various plastic resins and compositions. With a 1,2-vinyl structure over 85%, this series provides high reactivity to thermal or light stimulation. Also, its characteristic structure gives it a low dielectric constant property which makes it ideal as an electrical or electronic material. There are three grades ( B-1000, B-2000, and B-3000 ) classified according to the difference in mean molecular weight. Viscosity, glass transition temperature and other properties vary according to the molecular weight, providing options for selection according to the desired properties.

G Series / Both-end Hydroxyl Group-terminated Polybutadiene
The G Series is a both-end hydroxyl group-terminated polybutadiene. As with the B Series, the structure of the main chain is composed predominately of 1,2-vinyl structure, but because it has hydroxyl groups at both ends, it can be developed for different uses. With the hydroxyl groups as the active sites, the G Series can be used as a diol component of polyester, polyurethane, and other polymers.

Modified Resins
JP Series / Epoxidized Polybutadiene
The JP Series is an epoxidized polybutadiene formed by introducing an epoxy group through oxidation of the vinyl group of 1,2-polybutadiene. It is used as a copolymer component of epoxy resin compositions. Because the JP Series has only partial epoxy introduction, it retains the plasticity and electrical properties derived from its 1,2-vinyl structure, which produces a setting material with characteristics different from those of general-purpose epoxy resins.

TE Series / Terminal Acryl Group Polybutadiene
The TE Series is a polybutadiene acrylate resin with (meth) acryl groups attached to both ends of either polybutadiene or hydrogenated polybutadiene via a urethane bond. Because of the reactivity of the (meth) acryl groups, this series can be used in various compositions such as for adhesives and paints.
