Molecular Tailor of Castable Polyurethane Elastomer with Low Free TDI Monomer Content Prepolymer

Abstract:

Article Preview

Castable polyurethane elastomer based on polytetramethylene glycol (PTMEG) and 2,4-toluene diisocyanate (TDI) was prepared with low free TDI monomer content prepolymer (LF-prepolymer), the structure and properties of the prepolymers and corresponding elastomers were characterized. The result showed that, LF-prepolymer exhibit low viscosity, low molecular weight and narrow molecular weight distribution. The polyurethane prepolymer based on LF-prepolymer show higher bashore rebound, lower compression set and better dynamic properties.
