Selection of Elastomeric Materials for Resilient Exterior Body Parts

Valence or bumper filler panels as well as other exterior automotive body components of painted elastomers have been used and are being considered more extensively for future models. Three types of materials are the prime candidates: EPDM rubber and thermoplastic or thermoset urethanes.

The parts, however, must perform adequately within the automotive design criteria framework of MVSS regulations, cost, fabrication, appearance, and style.
