Polyurethane adhesive is made of 1, 4-bdo, MDI and polycaprolactone glycol which is high crystallinity, very high crystallization velocity and large cohesive strength.
BACKGROUND: High-porosity polycaprolactone (PCL) nanofiber scaffolds have a good multi-pore structure for the adhesion and proliferation of vascular smooth muscle cells and perfect biocompatibility.
