Which Parts of a Car's Exterior Are Made of Plastic?

[Amir]

Several parts of a car's exterior are made of plastic: 1. Bumper Cover: Also known as the "bumper," it is actually just the auxiliary shell of the bumper, not the main structure. The bumper cover serves to absorb impact and energy, operates in relatively complex environments, and is large in size. Therefore, it is typically made of polypropylene (PP) due to its lightweight and good corrosion resistance. 2. Grille: Nowadays, many car models feature chrome-plated grilles, giving them a strong metallic appearance, but in reality, they are also made of plastic. The main function of the grille is to cool the engine and manage airflow at the front of the car, requiring excellent material plasticity—making plastic the ideal choice. 3. Headlight Covers: Headlight covers must ensure long-term use without affecting brightness and protect the headlights, demanding good plasticity, high transparency, and sufficient hardness. Therefore, high-performance optical plastics like polycarbonate (PC) are the perfect choice for headlight covers, as they offer high strength, UV resistance, and excellent toughness and light transmission.
