Does the PUR foam contain formaldehyde?
No. Our foam system is, and always has been, an MDI base and does not contain urea-formaldehyde. Urea formaldehyde-based foams were used in the 1970’s as a field-applied, spray-in-place insulation system. These foams are no longer used. However, the adhesive used in the OSB is manufactured with some Phenol resins. Most OSB manufacturers are now using a combination of Phenol and MDI resins. Some of the newer mills are producing board with 100% MDI resins. Phenol resins used in OSB do off-gas. The amount of off-gassing is listed as TL (trace levels) and is well below any set threshold. As a TL, it is considered more than safe and does not pose any health problems.
