Clean air and a quiet ride with low-MDI foam.A patented low-MDI formulation of polyurethane acoustical foam is featured in the new 2004 Dodge Durango. Betafoam from Dew Automotive, Midland, Mich., is injected into the A, B, and C pillars and rockers to create an acoustical seal that helps manage road and chassis noise, vibration, and harshness Noise, Vibration, and Harshness, also known as Noise and Vibration, abbreviated to NVH and N&V respectively, is the name given to the field of measuring, and modifying, the noise and vibration characteristics of vehicles, particularly cars and trucks. (NVH NVH Noise, Vibration and Harshness NVH Nahverkehr Hohenlohekreis (German) NVH Noise Vibration and Harshness ). The new foam formulation results in a 98% reduction in MDI (1) (Multiple Document Interface) A Windows function that allows an application to display and lets the user work with more than one document at the same time. emissions compared with conventional MDI systems and well below both the OSHA OSHA n.

According to Dew, processors do not have to operate a down-draft ventilation booth as is required with conventional PUR foam, which saves both operating and maintenance costs. Betafoam is available in several low-MDI versions. Tel: (248) 391-6386, www.dow.com [ILLUSTRATION OMITTED] |
