An all-TPO instrument panel in Chevrolet’s Colorado and GMC’s Canyon compact pickup trucks is the first of its kind for GM in North America. All major components of the IP are molded of Solvay’s Sequel 2380 thermoplastic polyolefin. Traditionally, GM instrument panels have been built using painted PC/ABS parts or vinyl skin-and-foam construction. The unpainted TPO, which is colored at the press, is a lower-cost alternative to both of these methods.

Sequel 2380 TPO was selected for use in these parts based on several of its performance properties, especially the impact requirements of the Federal Motor Vehicle Safety Standarsd 201 and 208. The TPO also demonstrates dimensional stability across a broad temperature range, which is critical in a large part intended for snap-fit assembly. The IP is designed with very tight gaps of 1 mm between the cover and the adjacent trim parts such as the knee bolster. The TPO also meets a minimum requirement of 15 newtons in a re-engineered scratch test that is becoming a standard among automotive OEMs. Additionally the material is more resistant to buzz and squeak noises that can be produced by traditional interior materials, resulting in the elimination of acoustic materials and significant cost savings

The instrument panel cover is molded by Intier. The cover and other IP parts are integrally colored at the press with a color concentrate supplied by PolyOne Corp. Intier assembles and sequences the instrument panel for just-in-time shipment to an assembly plant.
