The article describes the advantages of using modern polymer materials for the manufacture of auto parts in the automotive industry. The authors have developed and presented a systematization of modern polymer materials, which are most often used in the automotive industry for the manufacture of both body and engine compartment (under hood) parts, and parts for internal equipment of a car. The studies made it possible for the authors to introduce a characteristic of the modern polymer materials properties that could to be used for the manufacture of a particular car part, as well as indicate brief chemical names (abbreviations) of polymer materials and their compositions (taking into account the requirements of world practice), indicating some properties, namely: heating resistance, solubility in organic solvents, etc.
It is indicated that the use of polymer materials in the automotive industry is based directly on the properties of the polymer material and the requirements for a particular auto part. In one of the tables, a list of polymer materials and parts that are made of a certain type of polymer material is outlined, in another table the information on feedback regarding the variation of polymer materials in the process of manufacturing a specific car part is gathered. Special attention is paid to the example of deciphering the stamp meaning, which is stamped on the inner surface of some polymer parts. The stamp reflects information on the type of polymer material from which the auto part is made, the presence of fillers and amplifiers in its composition, as well as their percentage. In addition, a list of the main types of modified polypropylene, a brief designations of polypropylene various modifications and their application in the automotive industry are presented. For the ease of use while forensic practice, the information on the properties and possibilities of using the most commonly used polymer materials in the automotive industry is summarized in table.
