This article will explore the causes of plastic car dashboard cracking and how to determine the severity of the crack.
Causes of Plastic Car Dashboard Cracking
Temperature: The primary cause of plastic car dashboard cracking is the temperature. Cars that are exposed to high temperatures, typically above an average of 73, are more prone to cracking.
When the temperature of the car’s interior rises, the chemical structure of the plastic that makes up the dashboard changes, causing it to become brittle. Additionally, exposure to direct sunlight accelerates the cracking process.
Dryness: Low humidity also causes plastic dashboard cracking. When the plastic materials are subjected to dry air, they tend to lose moisture, which makes them brittle.
This happens because plastic dashboards expand when exposed to a damp environment. The expansion helps to keep the dashboard smooth, however, when the moisture content in the environment drops, the plastic contracts, causing the dashboard to crack.
Chemical Exposure: Chemical exposure is another culprit of plastic dashboard cracking. Certain cleaning agents, including harsh chemicals that are meant to clean the dashboard, can do more harm than good.
Chemicals, when directly applied to the dashboard, cause its fibers to break down, which in turn causes the dashboard to crack. Additionally, exposure to fuel and other petroleum products speeds up the cracking process.
Age and Wear and Tear: The dashboard will eventually get old, and with time it will become weak, fragile, and subjected to normal wear and tear. As it ages, it is more prone to cracking, especially if it’s not maintained properly.
How to Determine the Severity of a Cracked Dashboard
Scratches: Scratches on the surface of the dashboard are typically cosmetic, thus not necessarily a severe cause for alarm. These can often be hidden by an adhesive dashboard cover or by using a plastic scratch repair kit.
However, if the scratch is deep, it may have penetrated the plastic, and it could be a warning sign that the problem goes beyond cosmetic. Cracks: If the dashboard has cracks, it is one of the more challenging problems to fix.
To determine the severity of a crack, evaluate its depth and width. If the magnitude of the crack is small, it can be fixed without expert help with dashboard crack fillers.
However, if the crack is significant and continues to expand, it needs to be fixed immediately as it may compromise the structural integrity of the dashboard. Missing Pieces: Missing pieces from the dashboard, compared to other types of cracks and scratches, are the most severe.
They can be caused by the car colliding with something at high speed, causing the plastic material to shatter. If you notice missing pieces from your dashboard, you should contact a mechanic or a professional car repair service as soon as possible.
