Summary:

The well-known hazards of diphenylmethane diisocyanate (MDI) have resulted in the development of foams with low MDI emissions for use in vehicle body cavities. While low MDI acoustic foams have been successfully launched in the automotive market, non-standard dispense equipment has been required. The latest low MDI acoustic foam development is dispensed via standard meter mix equipment, at the volumetric ratio of 1:1, enabling capital reduction for ventilation and application processing.This paper describes the benefits associated with using a 1:1 low MDI foam system. Industrial hygien testing and qualification of this system as low MDI are reviewed. Acoustical performance testing including insertion loss and sound absorption are discussed
