Advances In Low-Density RRIM Foam for Automotive Interior Trim 940704

Low-density polyurethane RRIM has drawn increasing interest as a material option for automotive interior trim. Past systems have suffered from poor thermal stability and the need to mold thick, heavy parts to attain sufficient impact resistance. A new low-density polyurethane/polyurea RRIM system has been developed with improved thermal properties. This paper serves to outline the system's physical properties with particular emphasis on thermal and impact performance. System performance will be compared to other interior trim materials.
