Automotive Heat Insulation and Reflective Solutions Reduce Car Temperature

When a car is left in the warm sun all day, it can result in dangerously hot interior temperatures. According to the National Highway Traffic Safety Administration, when outside temperatures are at 80°F or above, the inside of our cars can reach up to 172°F.

Here are a few heat management solutions that engineers can integrate to reduce vehicle interior temperatures:

Efficient thermal insulation in cars  

Foam can be used as an insulator. Conventional foam is too thick for automotive applications but this new foam is thinner thanks to microscopic, dense structures engineered by BASF. It offers five to seven times better insulation than conventional foam of the same thickness so it can be placed into tight spaces of a car and still maintain thermal insulation properties.

Heat reflective window film

This feature can be incorporated into the vehicle windshield and side windows. This film created by BASF reflects most of the near solar infrared radiation but doesn't inhibit any other frequencies, such as a cellphone or GPS signals, a necessity in today's connected world. It is also fully colorless and transparent for visible light.

Cool pigments for solar reflective paints

BASF has new pigments that allow black and other dark surfaces to reflect the sun's heat. These heat reflective pigments can be used in exterior coating applications and interior applications such as the dashboard or leather seats. Typically carbon black only reflects five percent of the sun's radiation. In comparison, these new pigments can reflect more than 30 percent.

BASF’s heat management solutions not only keep the vehicle interior cooler but also reduce the amount of energy needed to run an air conditioner. These solutions enable vehicle interiors to be less sensitive to external heat and maintain a comfortable temperature for drivers and passengers.
