Physical-chemical tests
Physico-chemical tests are mainly used to evaluate the properties and quality of plastic materials in various industrial applications. In general, a wide variety of test methods are used to provide rapid information on chemical resistance, formulation components, molecular structure and basic physical and technological properties. The results of these tests are used for general quality assurance, for improvements in product development and for compliance with a wide range of industry standards.

Various types of sample materials are used for physico-chemical tests in order to evaluate their properties and interactions with other substances under different conditions. Typical samples include plastics in the form of granules, semi-finished products, molded parts or films. The selection of samples and the sample quantity depend on the requirements of the tests, for example whether only chemical or physical-technological properties are to be examined. The samples should be representative of the actual area of application in order to achieve realistic results and must also usually be prepared extremely carefully to ensure accurate measurement results, e.g. by cutting, machining or grinding.
The technical test equipment for carrying out physical-chemical tests is particularly diverse due to the large number of different measurement methods in this category. A wide variety of vessels, containers, measuring devices and safety equipment are particularly important for carrying out storage tests. In addition, environmental simulation chambers optimized for special stresses are often used here. In addition, high-precision analytical measuring devices are also used to determine specially defined physical and chemical parameters or properties, which are often listed in material data sheets, for example.
Physico-chemical tests are particularly important in the quality control of plastic products, as the underlying measurement methods can usually be carried out quickly and require comparatively little equipment. Regular tests allow deviations in production processes to be detected and corrected at an early stage, which leads to an improvement in product quality. In addition, physical-chemical tests are often included in various product standards in order to meet legal or special manufacturer requirements and to ensure the safety of end users.
