The application of automobile plastic products in automobile interior decoration mainly focuses on several aspects such as the instrument panel, the roof of the car, the decorative plate of the door, and the sound insulation of the car.

The dashboards used in cars now can be divided into hard and soft dashboard hard dashboards that are generally used in light, minivans, and a single injection takes shape. This instrument has a large size and no skin. The surface quality is very high and requires high temperature and heat resistance and rigidity. Materials can be modified, PPO, ABS, PP etc. The soft - quality panel consists of three parts: epidermis, skeleton and cushioning material. The average grade car adopts the PVC/ABS sheet material vacuum to form the surface of the dashboard, such as faw-jetta, Shanghai santana sedan. The medium - grade car is made of powder PVC, which can be used to shape the skin of the dashboard, such as faw audi and small red flag sedan. The skeleton materials have iron plates (such as audi and red flags), cardboard (such as jetta and santana), ABS, modified PP, etc. In order to facilitate the recycling, it is developing thermoplastic polyolefins (TPO), modified polypropylene skeleton, polypropylene foamed materials. With the installation of the airbag in the car, the instrument panel has lost its safety requirement. So as long as the appearance quality is solved, it is feasible to adopt the low cost hard dashboard.
