"Polyester polyol with good adhesion and 1500% elongation at break" in detail
L3009 copolyester polyolIntroduction: L3009 is a medium molecular weight linear copolyester polyol with terminal hydroxyl group. It is liquid at room temperature. It can increase open time, improve flexibility, reduce melt viscosity and improve resistance to non-reactive polyurethane hot melt adhesives in reactive polyurethane hot melt adhesives. The role of polar substrate bond strength. Widely used in the production of reactive polyurethane hot melt adhesives for the automotive, wood, packaging, textile, book and sandwich panel manufacturing industries.
