WhisperTech V0 foams now provide excellent engine-bay sound management capabilities, while exceeding industry regulations for flammability of polymeric materials according to the supplier. WhisperTech UL-94 V0 rated foams self extinguish once exposed to an open flame in both horizontal and vertical test protocols. This formulation can also be specifically engineered to meet specifications including; coloring including black, heat aging, humidity aging, and no-drip performance.
WhisperTech foams can be fabricated in mechanically cut sheets, or molded into custom fit complex geometries, to meet exacting levels of acoustical performance. Domenic Sinopoli, Executive Director of Sales and General Manager of StrataForm at The Woodbridge Group, states: "WhisperTech UL-94 V0 rated, low-density flexible urethane formulations are used to balance cost and NVH performance requirements for hood liners and dash insulators. This solution also offers excellent thermoforming performance, using a variety of face materials to optimize the finished product."
Pejman Hashemi, WhisperTech NVH Solutions Product Manager at The Woodbridge Group, notes: "These extreme flame retardant formulations are available for a wide range of molded components in contact with the engine such as beauty covers and various acoustical insulators for manifolds, valve and cam covers, fuel rails, air intakes, and pumps. Additionally, these products can integrate fasteners and mounting brackets for ease of assembly."
WhisperTech V0 foams are available in a wide range of density, hardness and thickness, to optimize cost and performance. They are offered in sheet stock and as molded components.
The Woodbridge Group and its partners in The World Polyurethane Alliance operate 60 facilities located in 18 countries as global leaders in the development and production of polyurethane and expanded polypropylene products. Automotive applications include components for seating, structural support, interior soft trim products, headliner systems, cargo management solutions, and engineered products for occupant protection and acoustical management.
