[ASA] Enhancing the weather resistance of radiator grilles

Located on the front of the car, the radiator grille's design element is as important as its function.

It is key in making the first impression of a car and sometimes even serves as the memorable identity of the brand.

Each car model has a different design of radiator grille to differentiate itself.

The grille's original function is a vent through which air passes for cooling radiators and engines.

It also protects the radiator from various foreign objects that may splatter on the front of the car while driving.

Because it is an exposed exterior part, the material is required to withstand the natural environmental factors such as light and moisture,

in addition to meeting the requirements for automobile parts.

As such, a material called ASA (acrylonitrile-styrene-acrylate) that meets these conditions is widely used to produce the grille.

In addition to the benefits of ABS (acrylonitrile-butadiene-styrene) as a functional plastic, it also has strong weather-resistant properties.

◆ ASA(Acrylonitrile-Styrene-Acrylate)
ASA is a copolymers of SAN and acrylic rubber. It is a high-performance plastic that has most of the benefits of ABS as well as excellent weather resistance.

It has minimal changes in physical properties and appearance even after an extended outdoor use.

It is used as the exterior material for cars, construction material, and furniture sheets.
