The current T-model in the E-Class from Mercedes has an especially large fuel filler flap, since it is intended to accommodate variable fueling options. This flap has recently been converted to the new Ultramid TOP 4000 fromBASF, a mineral-filled semi-aromatic polyamide (PA 6/6T).
The fuel filler flap for the T-model in the Mercedes E-Class is, among others, painted in the colors iridium silver metallic and obsidian black metallic. It is no longer made of metal, but rather the new automobile body plastic grade with the designation Ultramid® TOP 4000 from BASF. This improved, conductive material is now stiffer than its predecessor and can, without additional effort, be painted together with the rest of the steel body using classic automotive coating techniques.

导电工程树脂是2007年推出的超大型TOP 3000的改进版本，主要具有更大的刚度和尺寸稳定性。就像其前身一样，新材料也适合在线绘画。这意味着：由超大型前4000罐制成的塑料组件，而无需额外的努力或成本，可以承受对身体其余部分进行的各种浴缸和绘画操作。因此，该材料代表了朝着轻质塑料汽车体迈出的另一步骤，从而进一步减少了燃料消耗和排放。
In the course of development, the BASF Verbund once again demonstrated its capabilities, as the experts at BASF Coatings GmbH in Münster contributed greatly to optimizing the new resins on the basis of their know-how in the fields of paint and coating. The fuel filler flap for the Daimler station wagon is manufactured at Kunststoff Schwanden AG in Schwanden (CH),
