on the properties of cast urethane elastomers


Polimery 1987, No 11-12, 475


DOI: dx.doi.org/10.14314/polimery.1987.475

Summary

The mechanical properties and fields of application of cast urethane elastomers have been presented. These elastomers have been obtained by crosslinking with low - molecular-mass chain extending and crosslinking compounds of prepolymers prepared from polyetherols (oligooxytetramethylene glycol or oligooxypropylene glycol) and tolylen diisoisocyanate. The possibility of using crosslinking compounds of lower melting point, as fo r example isobutyl 4-chloro-3,5-diaminobenzoate (Baytec PU 1604), instead of hitherto used crosslinking agent with higher melting point — 3,3'-dichloro-4,4'-diaminodiphenylmethane (MOCA) has been demonstrated.
