| Abstract: | Rigid polyurethane foam was made by environment friendly foaming agent.The factors which(affect) the structure and the property of rigid polyurethane foam were studied.The factors include the composition of polyether polyols, the amount of foam stabilizer and catalyst.Research results show that the match between gelatinizing and foaming rate could be achieved by changing(catalyst(organotin)) amount,and thus the structure and property of rigid polyurethane foam could be controlled.The results also indicate t... |
