| Abstract: | A polyester for POlyrulethane adhesive were synthesized, and the synthetic process of PU adhesivefor magnetic tapes was introduced. The influences of the raw materials, reaction temperature andtime the mole ratio between NCO to OH, and sovents on the synthesis and properties of thepolyurethane adhesive were discussed. The essential POints of adhesive properties for magnetic tapewere also examined. |
