PCD_BENEBiOL™

Biomass-based polycarbonatediol with superior characteristics

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.

Furthermore, BENEBiOL™ enables your product to be more sustainable, as some of raw materials of BENEBiOL™ are biomass-based.

Characteristics of polyurethane resins based on BENEBiOL™

  • sustainable:
    biomass-based(some grades:non-edible biomass-based)
  • long life and good appearance:
    transparency, stain resistance, chemical resistance, durability, toughness, weather resistance
  • unique touch and feel:
    flexibility, soft feel and touch, high hardness, good fit

STORAGE AND HANDLING

BENEBiOL™ should be sealed in a container with dry nitrogen since it is moderately hygroscopic. Some of NLDB/D and NLB grades are solid at room temperature, and it can become a colorless transparent liquid when heated. Before using “BENEBiOL™”, it should be heated at temperature above its melting point.

Under transport regulations, “BENEBiOL™” is not classified as UN hazard class. “BENEBiOL™” has low volatility and will not spontaneously ignite at room temperature. In the event of fire, dry chemicals foam and plenty of water spray are effective for extinguishing.

Safety glasses and protective gloves should be worn when handling “BENEBiOL™”.

For further details, please refer to Safety Data Sheets issued by Mitsubishi Chemical Corporation.

“BENEBiOL™” are produced for industrial applications. If the intended use for “BENEBiOL™” is for body contact applications such as pharmaceuticals, food and cosmetics, please contact Mitsubishi Chemical Corporation in advance.
