Can a Car Be Damaged by Sun Exposure?
1 Answers
Prolonged exposure to sunlight can accelerate the aging of plastic components in a vehicle. For example, the dashboard filled with wiring, car doors, and sealing rings around the sunroof edges are particularly vulnerable. Sealing rings, in particular, are prone to aging and cracking after sun exposure, significantly reducing their sealing performance, which may lead to water leakage or seepage. Here are some items you should avoid leaving in your car during summer: 1. Lighters: Small and easy to forget, yet highly dangerous, as they contain liquid butane that can explode when internal pressure increases due to heat. 2. Bottled water: Stored in a sun-exposed car for a certain period, it can release harmful substances. Continued consumption may not only fail to quench thirst but also pose health risks. 3. Eyeglasses: Especially reading glasses, as their convex lenses can focus sunlight, potentially causing a fire. 4. Perfume (in glass bottles): The volatile components can produce flammable gases, with a critical packaging point of 49°C. Tests show that on a summer afternoon, an uncovered car can reach 65°C in just 15 minutes of sunlight, increasing the risk of explosion.
