What material is wing mirror cover made of?

The material of wing mirror covers, also known as side mirror covers, can vary depending on the car model, year, and trim level. However, the most common materials are:

  • Acrylonitrile butadiene styrene (ABS): This is a type of plastic that is known for its strength, durability, and affordability. It is often painted to match the color of the car.
  • Polypropylene (PP): Another type of plastic that is similar to ABS, but it is lighter and more flexible. It is often used on lower-end cars.
  • Polyurethane (PU): This is a more expensive material that is used on high-end cars. It is very durable and can be painted or left unpainted.
  • Metal: Some high-performance cars have wing mirror covers made from metal, such as aluminum or chrome. These covers are very durable and can add a touch of luxury to the car.

In addition to the material of the cover itself, wing mirror covers may also have a clear plastic coating that helps to protect them from scratches and UV rays.

Why can ABS be thermoformed car exterior?

ABS (Acrylonitrile Butadiene Styrene) can be thermoformed for car exteriors due to its combination of several key properties:


  • Melting Point: ABS has a relatively low melting point compared to other plastics, typically around 220°C – 250°C. This allows it to be easily heated and softened for shaping during the thermoforming process.
  • Good Formability: Once softened, ABS exhibits good formability, meaning it can be readily stretched and molded into complex shapes without tearing or breaking. This is crucial for replicating the intricate contours of car exterior parts like wing mirrors.

Strength and Durability:

  • Impact Resistance: ABS has excellent impact resistance, making it suitable for exterior applications exposed to potential impacts from road debris or minor collisions. This is crucial for ensuring the safety and functionality of components like wing mirrors.
  • Weather Resistance: ABS exhibits good weather resistance, meaning it can withstand exposure to sunlight, rain, snow, and other elements without significant degradation or discoloration. This ensures the longevity and aesthetic appeal of exterior parts.

Other Advantages:

  • Lightweight: ABS is lighter than many other plastics used in cars, contributing to weight reduction and improved fuel efficiency.
  • Paintable: ABS readily accepts paint, allowing for customization of color and finish to match the overall car design.
  • Cost-effective: Compared to other materials with similar properties, ABS is relatively cost-effective, making it a practical choice for large-scale automotive production.

While ABS does have limitations, such as lower heat resistance compared to some metals, it presents a well-rounded combination of properties that make it highly suitable for thermoforming various car exterior parts, including wing mirrors, spoilers, and trim panels.

Here are some additional points to consider:

  • Specific grades of ABS: Different grades of ABS exist with variations in properties like impact resistance and weatherability. Manufacturers choose the most suitable grade based on the specific application and performance requirements.
  • Surface finishing: While ABS is paintable, additional surface treatments may be required for specific textures or enhanced weather resistance.
  • Environmental concerns: As with any plastic, responsible recycling and disposal of ABS car parts is important to minimize environmental impact.

I hope this explanation clarifies why ABS is a popular choice for thermoformed car exterior components!
