Flexible polyurethane foam, process for preparation of polyurean rusty foam, test for preparation of polyurean, and, use of co2 as an air flow enhancer.

摘要

"Flexu00ecvel polyurethane foam, process for preparation of the same, ru00ecgida polyurethane foam, process for preparation of the same, and use of the Co ~ 2 ~ as the breeder of the air flow.Process for the preparation of rigid and flexible polyurethane foam by reaction of a poliisocianato and a polyol in the presence of water and Co ~ 2 ~.The foams obtained do not show significant glass transition at temperatures between - and + 100u2039c 25u2039c and possess properties of air flow improved.
