The development of the economy and the continual competition for the customer brings new impulses in the area of production, trade,
and consumption. Manufacturers are increasingly looking to meet customers, wanting to meet the needs of a wider range of consumers with
their manufacturing and sales strategy, with an emphasis on the environmental and economic impact of their products. Therefore, recycling
and re-use of raw materials are very important today. The paper is focused on experimental studying and testing of material relaxation of
recycled polyvinyl butyral (PVB). Polyvinyl butyral foil is one of the most important parts of the windscreen or safety glass as an interlayer.
Polyvinyl butyral carries a large amount of chemically bonded energy. Less harmful vapours are released during combustion of PVB than
when combustion of heating oil. However, the price of energy obtained from such a waste product is sometimes lower than the price of
energy obtained from oil. Given the global polyvinyl butyral waste production, the price for this attractive commodity is very reasonable. It
ranges from 0.25 € to 0.50 € per kilogram of this thermoplastics. After homogenization, the mixture polyvinyl butyral was compressed to the
test samples of prescribed shape and size under action of pressure and heat. Recycled polyvinyl butyral was investigated under tensile test
and material stress relaxation. Based on the results, it can be stated that the material had the max. values of a tensile stress 0.78 MPa, the
strain of the material subject to tensile strain was from 410 % to 520 %.
