In the PSA B62 0300 standard developed by Peugeot automobile company, the requirements of thermoplastic, thermoset, thermoplastic elastomer and rubber materials used in automobile production are explained, classification information is given and their specifications are defined.
Both strong and lightweight, plastics increase the safety, performance and comfort of a wide variety of products used every day. Plastics consist mainly of macromolecules processed into molded parts, films, fibers or finished or semi-finished products. All plastic materials have unique properties, special additives and coatings. The following specifications are considered when selecting for the application: hardness, breaking strength, formability, flexibility, temperature restrictions and chemical resistance.
Plastics commonly used in the automobile industry are divided into three groups according to their physical properties: thermoplastics, thermosets and thermoplastic elastomers.
Thermoplastic (heat softening plastic) materials are a type of plastic polymer material that becomes pliable at high temperatures and less flexible after cooling. These materials can withstand very high temperatures. Unlike thermosets, thermoplastic materials can be molded as often as desired by cooling and reheating, as long as the material does not overheat.
Thermosets are plastics that retain their state and shape after curing due to spatial crosslinking. After curing, its polymers can no longer be dissolved. This type of plastic exhibits mechanical and chemical resistance even at high temperatures and is popular in electrical installations.
Elastomers (elastic polymers), on the other hand, are polymers that are held together by weak intermolecular forces, usually showing low Young's modulus and high yield strength or high breaking stress. These plastics have unique properties that allow them to deform or stretch under extreme tensile and compression loads and then return to their original shape.
Another material widely used in the automobile industry is rubber. Natural rubber is produced from plants and is classified as a polymer chemical compound with large molecules consisting of many small molecules of the same species. Some polymers occur naturally, some are produced in laboratories.
Our organization also provides testing services for thermoplastic, thermoset, thermoplastic elastomer and rubber materials within the scope of PSA B62 0300 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
