Polyurethane and Emissions
Polyurethane composites contain no styrene and do not generate large amounts of volatile organic compounds (VOCs). Polyurethane formulations for reaction injection molding and composites do contain diphenylmethane diisocyanate (MDI), which is a regulated material. Because of the low vapor pressure of MDI and the results of industry emissions tests, emissions from polyurethane composite processing should be negligible. Bayer’s experience in workplace exposure monitoring indicates that unless MDI is heated or sprayed, the likelihood of exceeding OSHA permissible limits is small. After the polyurethane is processed, there are no emissions of MDI from the part.
To help its customers safely store, handle and process polyurethanes containing MDI, Bayer MaterialScience has extensive product safety and product stewardship support and programs. For example, in North America, the BayCare Progressive Product Stewardship Program provides customers with extensive tools, materials and on-site support services.
