Scientific research has proven that listening to properly chosen music while driving a car relieves the driver’s stress and thus reduces the emotions on the road. However, a good audio system is not enough to achieve this effect. It is also necessary to optimally soundproof the cabin, which can be provided by components made of modern EPP foams used in its construction.

It seems that much has been already said about ergonomic car interiors and the limits of possibilities have already been reached. A great role in this process is played by modern plastics and especially by the light expanded polypropylene (EPP).

The automotive industry has been using a variety of plastics extensively in the past few decades. Presently about one third of the components building up a modern vehicle are made from plastics. Expanded polypropylene – EPP in one of the most popular and most valued ones among them.

The increasing use of plastics in the automotive industry is a response to the need of reducing the weight of vehicles and improving fuel efficiency, complying with the strictest regulations on greenhouse gas emissions and the demand for environmentally friendly products.

3D digital technology has a huge impact on the automotive industry. In the sector where technological innovation is caused by the constant desire to remain competitive, the development of 3D printing will bring about changes in the coming years due to its huge benefits in terms of economic and production sustainability.
