Did you know that the pieces that favor the aerodynamics of vehicles are made of polyurethane? The qualities of lightness and strength of these pieces make polyurethane systems one of the most suitable materials to make them.
These pieces are intended to intervene in the airflow around the vehicle and they are known as spoilers. The front and rear skirts and the ailerons are some of the pieces known as spoilers that are made of polyurethane.
From aeronautics to our garage
The origin of vehicle spoilers is based on aircraft ailerons and, although both aim to improve aerodynamics, there is an important difference: spoilers in vehicles are inverted compared to those in an airplane. This is because spoilers help increase the adhesion of the car, eliminating some of the air that penetrates under the vehicle.
At the beginning, spoilers were placed in the rear of the vehicle, imitating the ailerons of formula 1 cars. However, spoilers can now be found mostly on the skirts and, on some models, also on the ailerons. Thanks to the incorporation of these elements, it is possible to increase the force exerted by the car on the road so that there is a greater friction between the tires and the asphalt.
Elaboration of polyurethane spoilers
The spoilers made with polyurethane systems have some qualities that favor the aerodynamics of the vehicles. The spoiler built of thermoplastic polyurethanes offers lightness, versatility to achieve the desired shapes, easy assembly and the possibility of painting or giving a metallic or chromed appearance.
In addition, polyurethane systems make spoilers to have a good resistance to external agents such as solar radiation, extreme temperatures, rain, etc. At the same time, we are investigating how to improve its adaptability to reduce damage in case of impact.
The elaboration of polyurethane spoilers can contribute to reduce the energy consumption of our vehicle.
Elastomer System 9163
Synthesia Internacional manufactures a polyurethane system that offers a solution for the manufacture of automotive spoilers. This is the elastomer system 9163.
This system is designed for the manufacture of molded pieces by rotomolding, with high hardness and good physical and mechanical properties, which are characteristics required by the manufacture of spoilers.
