Plastics testing –
efficient and safe with DSPro@skz

Whether raw material, recycled material or test specimens - our test laboratory analyzes the properties of your materials

Plastics are used in numerous industries, not least because of their specific material properties, which in some cases exceed those of other materials. Safety aspects often also play a major role here. A prerequisite for safe and high-quality products is knowledge of the actual material properties of the plastics used. These material properties are analyzed and determined as part of plastics testing.

Our specially developed material analysis, Data Sheet Process (DSPro), offers you comprehensive support in determining decisive characteristic values for your plastics. We can test granulates, multipurpose test specimens in accordance with DIN EN ISO 3167 and sheets for you, regardless of their subsequent areas of use or applications. Whether comparability tests or the creation of data sheets – DSPro@SKZ optimizes the entire process to provide you with cost-efficient results. You can rely on our expertise and state-of-the-art technologies.

Plastics testing – it all depends on the right method

Numerous test methods are used in our test laboratory to carry out a material analysis. Whether mechanical, rheological or thermal tests – our experts determine the relevant material parameters and thus provide an important assessment criterion for safe use in the subsequent component.
