Abstract

Polyester and polyether polyols have been used to manufacture high quality products since the earliest days of the polyurethane era. They are cost effective raw materials which impart excellent abrasion and solvent resistance, oxidative stability, tear and tensile strength to the polyurethane. In this report, a series of three polyurethane (PUs) based on a mixture of two polyols (polyethyleneadipate diol-PEA 2000 and polytetrahydrofuran PTHF 1400) was prepared. Diphenylmethane diisocyanate (MDI) was utilized in the preparation of PUs. Ethylene glycol (EG) and Glycerin (Gly) were used as chain extenders. The physico-mechanical properties (hardness, stress-strain, resilience, and abrasion resistance) of this PUs were measured according to standard methods. Thermal analysis (TGA and DSC) were used for characterization. The structures were confirmed by infra-red analysis (IR)..
