Process for producing high density elastic polyurethane using a combination of 4-methyl-1-(2-dimethylaminoethyl) piperazine together with another tertiary amine catalyst

摘要

Process for producing a high density elastic polyurethane of reduced weight having excellent resistance to bending, which employs as catalyst 4-methyl-1-(2-dimethylaminoethyl)piperazine or a mixture of 4- methyl-1-(2- dimethylaminoethyl)piperazine and another tertiary amine compound as co- catalyst.
