CAST POLYURETHANE COMPOSITION Russian patent published in 2019 - IPC C08L75/06 C08G18/68 C08G18/76

Abstract RU 2686187 C1

FIELD: manufacturing technology.

SUBSTANCE: invention relates to formulations of cast polyurethane compositions intended for production of structural articles in oil, oil producing, automotive and other industries. Cast polyurethane composition contains polyethylene glycol adipate with molecular weight 1,850–2,000, 2,4-toluene diisocyanate, 1,1,1-trimethylol propane and chain extender. Chain extender is 2,2-bis-[4-(2-oxoethoxy)phenyl] propane.

EFFECT: obtaining polyurethane based on cast polyurethane composition with elasticity exceeding by 10–30 % and its preservation in time, and heat resistance by 28–37 °C.
