Описание материалов:
Bayfill EA 2003 is a low-density, semirigid polyurethane foam system designed for automotive interior applications. It produces a friable foam which has the ability to absorb more energy in applications where space is limited. The Bayfill EA system is an excellent choice where occupant impact protection above the vehicle beltline is required or desired. Foams made with Bayfill EA 2003 can be incorporated into vehicle headliners and pillar covers for improved occupant protection in collisions. Because such foam is friable, it should be considered a sacrificial energy absorber and should be replaced after damage by an impact. The Bayfill EA 2003 system is supplied as two components. Component A is a polymeric diphenylmethane diisocyanate (PMDI) and Component B, is a polyether polyol system. As with any product, use of Bayfill EA 2003 system in a given application must be tested (including but not limited to field testing) in advance by the user to determine suitability.
