Our Copolymer PCD(Poly carbonate diol) is liquid at room temperature, and offers heat/hydrolysis/chemical/abrasion resistance, good softness and lower crystallinity.  The solubility and elasticity are also excellent comparing to standard solid homopolymer PUD.

T5652, G4672 and G3452 have 400-900% solubility for measure solvents(Toluene, DMF, Ethyl acetate MEK etc.)

This product is recommended for polyurethane dispersions, polyurethane elastomers, and for plastic coatings.

Features & Benefits

●DURANOLTM has a high hydroxyl purity. It can provide high Mw-Polyurethanes.
●Good physical properties in terms of heat, hydrolysis, chemical, abrasion resistance.
●Copolymer PCD has better elasticity than Homopolymer PCD
