Descripción

General description

Poly[4,4′-methylenebis(phenyl isocyanate)-alt-1,4-butanediol/di(propylene glycol)/polycaprolactone] (PU/PCL) is a polyurethane solution that can be used as a shape memory polymer and a reinforcing unit for enhancing the mechanical and thermal properties of the base materials. It is biocompatible and finds usage in endothelial proliferations. PU/PCL contains polycaprolactone (PCL) that facilitates the hydrophobic properties of the polymeric matrix.[1][2][3]

Application

Automotive fascia, cable jackets, side trim, fabric laminates, health care tubing, catheters, transdermal patches and in seals casters, shoes, bushings and wheels.

PU/PCL can be used in the formation of a polyurethane membrane for effective gas separation.[4] It can also be used to synthesize reinforced hydrogel with good thermo-mechanical properties for biomedical applications.[5][6]

Features and Benefits

Tough, high-performance, wear-resistant elastomer with good clarity, chemical resistance, flexibility and toughness. Can be used in current form or further polymerized. Low compression set
