Feature and Application

Introduction of polycarbonatediol (PCD)

PCD has a carbonate skeleton and is a long-chain diol having hydroxyl groups at its both ends.
Generally, polyurethane using PCD offers excellent heat resistance, hydrolysis resistance, chemical resistance, weather resistance, and mechanical properties when compared to those using polyether polyol (PTMG) or polyester polyol (PHA/PCL).

PHA:Poly1,6-hexamethylene adipate(Polyester polyol)
PCL:Polycaprolactone polyol(Polyester polyol)

Feature of DURANOL™

Although PCD offers excellent durability, hydrolysis resistance, and chemical resistance when compared to other polyols, its flexibility is inferior to that of the polyols.
Our PCD, DURANOL™ maintains the features of PCD as described above and has the following features when compared to PCD of homopolymer type due to its improved flexibility.

Major application of DURANOL™

DURANOL™ is suitable for applications that require durability in particular, such as leather (synthetic leather, artificial leather, etc.), paint, adhesive, and elastomer.

[Paint]
Use of DURANOL™ allows you to obtain a polyurethane paint with excellent scratch resistance, chemical resistance, abrasion resistance, and weather resistance. Above all, liquid type DURANOL™ is amorphous and its stress at a low strain is smaller than that of solid type PCD, thus it can offer softer feeling as a binder of a soft feel paint. Additionally, its solubility to solvents is high and thus, for solvent paints, allows reduction of the amount of solvent used and higher solid content. Furthermore, for water-based paint, it disperses into water with a small amount of solvent (or without solvent) and thus allows environmentally friendly paint design. DURANOL™ is used in a wide range of fields such as automobile, home appliances, mobile devices, and general industries

[Leather]
Use of DURANOL™ allows you to obtain a polyurethane resin with excellent hydrolysis resistance, moisture heat resistance, chemical resistance, and abrasion resistance, as well as to improve the durability of polyurethane resins for leather, such as a binder of synthetic leather/artificial leather and surface treatment agents for various leathers. DURANOL™ is used in a wide range of fields such as automobile, furniture, shoes, clothing, and sundry goods.

[Elastomer]
Use of DURANOL™ allows you to obtain thermoplastic and thermoset elastomer and resin with excellent chemical resistance, abrasion resistance, and flexibility. DURANOL™ is used in a wide range of fields such as various rollers, rolls, belts, sealing, and gaskets.

[Adhesive]
Use of DURANOL™ allows you to obtain a polyurethane adhesive with excellent moisture heat resistance, hydrolysis resistance, and flexibility. DURANOL™ is used in a wide range of fields such as various structural materials, electronic materials, and general industries.
