Have you ever wondered what modern cars are made of? Most people would probably guess that cars contain metal, but that only accounts for about half of the materials, depending on the model. In fact, cars also contain a large percentage of plastic resin. Learn how the automotive industry uses plastic resin here.
Car manufacturers use plastic resin because it’s durable and lightweight. That means it can hold up to daily wear and tear without adding tons of weight to the car. Manufacturers have to find the perfect balance when it comes to weight. Too light, and the car won’t perform well in collision safety tests. Too heavy, and the car’s fuel efficiency will suffer.
Resin is a common choice when manufacturers are making dashboards for cars. The dashboard is the part of the vehicle that acts as a protective case for the steering housing, the radio and GPS, and the car’s speed and fuel gauges. The dashboard also houses the car’s passenger airbag. If you’re ever in a front-on collision, you want the dashboard to absorb as much of the shock as possible, and resin does a great job of doing that.
You may be surprised to learn that there is also resin inside your car’s brake pads. Brake pads create a lot of heat through the friction of stopping your car. Resins are an excellent option for absorbing all that excess heat without melting or distorting.
One of the last places you’d expect to find resin in your car is the engine, but that’s exactly where it’s most important. As we said in the previous point, certain types of resin are extremely heat resistant, making them the perfect choice for engine parts. Thanks to this heat resistance, you don’t need to add fire retardants, which take up space. Resins are also resistant to oils, solvents, acids, and alkalis that you find in the engine.
The automotive industry uses plastic resin because it’s lightweight and resistant to chemical change. If you’re a vehicle manufacturer, make sure to choose the right resin supplier to be sure you’re getting high-quality materials. You never want to take risks on the materials necessary for vehicle safety.
