While emissions specifications guiding the use of flexible polyurethane foams in automotive applications have existed for over a decade, the rigor with which these specifications are being enforced and scrutinized appears to be increasing. In a market where lower emissions used to be a desired trait, they are quickly becoming a requirement of sale for many OEMs. In response to this market trend, Air Products and Chemicals, Inc. has focused recent development efforts on reducing emission contributions from the specialty additives required to produce high quality flexible foams. This paper presents a new family of reduced emission silicone surfactants developed specifically for automotive foam applications. These surfactants offer the same excellent processing, foam appearance and physical properties as conventional surfactants, however they boast significant reductions in both siloxane and carrier emissions when subjected to industry standard emission tests such as VDA278 and SAE J1756. The performance of reduced emission cell regulator and bulk stabilizer technology for TDI/MDI-based foams, as well as a cell regulator for MDI systems, will be discussed herein.
