Allgemeine Beschreibung
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.
Anwendung
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. It can also be used to synthesize reinforced hydrogel with good thermo-mechanical properties for biomedical applications.
Leistungsmerkmale und Vorteile
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
