Aldehyde Emissions from Flexible Molded Foam

摘要

Automotive OEM requirements for indoor air quality have made volatile organic compounds (VOC) and aldehyde emissions increasingly important to the polyurethane industry. As more OEM's implement aldehyde emission requirements Air Products' is actively developing offerings to enable our customers to meet the large range of requirements in different regions. This paper will detail efforts to develop an aldehyde scavenger to lower aldehyde emissions from molded polyurethane foam. There are multiple methods used to measure aldehyde emissions and it is challenging to get reproducible results. Air Products has developed techniques to obtain reproducible emission results. Experiments were run to identify the different sources of aldehydes in foam emissions and are detailed in the paper. Different chemistry families have been looked at for their ability to react with formaldehyde, acetaldehyde, and acrolein and both experimental and computational results will be shared as well as the physical properties and emissions of three new aldehyde scavenger prototypes.
