The objectives were to find the optimization composition of open cell rigid polyurethane raw material and the foam physical properties. The effect factors of composition and properties include the ratio of isocynate and polyether; stirring speed, mixing temperature and additives. The solid fraction was found to increase as the mixing temperature increasing. The ratio of isocynate and polyether between 1.1 and 1.2, the solid fraction was less then other ratios. In this research, the ratio of open cell was found almost 100%, however, there had non-uniformity cell size, over reaction those problem. Wei-Han Tao 陶惟翰 1999 學位論文 ; thesis 106 zh-TW |

The effect factors of composition and properties include the ratio of isocynate and polyether; stirring speed, mixing temperature and additives.
