As in the cushion formulation, these lower FTC delta values demonstrate how these newly developed additives enhance crush-out capabilities. Furthermore, this effectively illustrates that the TPR window can be extended as compared to the control formulation. 2d Cushion and Back Formulation Machine Evaluation Without TPR Several polyurethane manufactures do not utilise TPR in their production process. The formulations evaluated in this study were designed to utilise TPR when producing polyurethane articles.

2 Low Emission Dimensional Stability Additives Another emerging need in the automobile market segment is for lower and ultimately no emissions of polyurethane foam additives into the environment. Current efforts revolve around automotive passenger compartment air quality improvements by reduction of the emissions typically from the current migratory additives used to produce interior foam components. These emissions can cause a variety of problems in the final application of the foam, ranging from odour to vinyl staining and window fogging.
