BioPTMG is a polyether polyol manufactured from plant-derived raw materials.
BioPTMG has the same performance as petroleum-derived PTMG as a raw material for polyurethane and polyester resins and has excellent impact, wear and hydrolysis resistance, flexibility at low temperatures, etc. Taking advantage of these characteristics, it can be used in a wide range of fields, from interior and fashion to industrial materials.

12BG (1,2-butanediol) is a branched glycol that has a primary hydroxyl group and a secondary hydroxyl group on adjacent carbon atoms. Mitsubishi Chemical Corporation offers two grades of purity. Both can be reacted with a dicarboxylic acid (e.g., phthalic acid or adipic acid) for use as a polyester polyol or a plasticizer, or reacted with an unsaturated dicarboxylic acid (e.g., maleic anhydride) for use as a raw material for unsaturated polyester resin. The high-purity grade 12BG is suitable for use as a solvent for inks and as a raw material for surfactants.

14BG (1,4-Butanediol) is a straight chain glycol with hydroxyl groups on both ends. It is used as a raw material for high performance polyester and polyurethane resins as well as for industrial chemicals like tetrahydrofuran and gamma-butyrolactone. Since 1982, Mitsubishi Chemical's Tokai plant has produced high-purity, high-quality 14BG from butadiene using our proprietary technology.

Polycarbonatediol, BENEBiOL™
[Close]

Polycarbonatediol(PCD) is a linear polycarbonate with hydroxyl groups at both ends. It easily reacts with isocyanate compounds(e.g. MDI, TDI, IPDI, H12MDI), and generates polymers with characteristics such as durability and chemical/hydrolysis resistance. BENEBiOL™ is the biomass-based PCD developed by our proprietary manufacturing technology. Because of “key monomer“ of each grade, polyurethane resins based on BENEBiOL™ will show an outstanding property level with regard to flexibility and chemical/stain resistance for example, in addition to the characteristics of conventional PCD. Besides, your product will be equipped with unique touch and feeling.Biomass-based polycarbonatediol with superior characteristics
