The table below shows qualitative comparison of the impact of polyols on polyurethane.
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 offers improved flexibility.
|Fungus resistance||Fair or Good||Fair or Good||Poor||Poor||Excellent|
|Oleic acid resistance||Good||Good||Poor or Fair||Fair||Poor|
Liquid type DURANOL™ (T5652•G4672 and G3452) offers excellent handling property and solvent solubility.
Solubility[wt%] (at 25℃)
Generally, DURANOL™ has a good compatibility with polyester polyols.
In the case of acrylic polyols, the compatibility depends on their types.
|9 : 1||7 : 3||5 : 5||3 : 7||1 : 9|
It can be seen that PCD polyurethanes are hard to decompose when compared to polyether urethanes and polyester urethanes.

It can be seen that PCD polyurethanes have a smaller swelling rate due to organic solvent when compared to polyether urethanes and polyester urethanes and copolymerized type DURANOL™ has an excellent swelling rate in particular.
