Use of heat flow meter in evaluating dynamics of polyurethane foaming
Six com. and an artifical polyurethane systems were foamed with n-pentane, cyclopentane, polyfluoroalkanes and H2O to study the heat flux d. during first 600 s of foaming and describe the process dynamics. The heat flux d. decreased with increasing amt. of the blowing agents used.
