Due to their diverse spectrum, materials made of rubber are used, for example, as tires, seals, dampers or protective elements in a wide variety of areas, from industry, traffic and personal needs to medical devices. In order to achieve the required property profile of the product and appropriate processing conditions as well under cost aspects, careful selection of the raw materials used is indispensable and quality-determining. 15 to 20 components are not uncommon and, due to impurities, reaction products and any substances absorbed in use, it represents a very complex chemical mixture compared to other material groups, whose analysis and evaluation we dedicate ourselves.
We carry out standard tests for you that you need, e.g. for approvals or monitoring, or detailed material analyses. In many cases, however, our investigations are individually tailored to the respective problem or question with the customer. The background is mostly failure analysis, quality control, product optimisation, purity, environmental aspects or questions from the areas of food contact and drinking water. In addition to specialists from the rubber industry, we also support inquiries from areas / branches of industry where there is no in-depth knowledge of elastomers. Where used articles are sometimes little noticed accessories and suddenly cause massive problems. In these cases it is not uncommon for our cooperation to begin, in addition to the recording of facts, with explanations of the special properties of the material and the possible connections. The DIK is therefore also the point of contact for suppliers in the field of automotive, pharmaceutical and medical technology and other industries.
As your service provider, we see ourselves not only as a supplier of measurement data, but especially as a problem solver. In addition to the given confident handling of the measurement techniques, this is guaranteed by the existing knowledge of raw materials, processes, properties and use. Long-time employees and the broad competence available in the DIK are important factors for that.
In addition to the analyses already listed, the following tests should be mentioned as examples from our extensive range of services, which we carry out not only on elastomers, but also on composite materials:
- Failure analysis
- Identification of material types, blooming, cross-linking systems, layers
- Determination of qualitative and quantitative compositions
- Comparison of crosslinking densities / degrees of vulcanization
- Determination of emissions and odours
Methods we use for this are for e.g.
- Infrared spectroscopy (FT-IR)
- Thermogravimetric analysis (TGA)
- Extraction and swelling measurements
- Various gas chromatographic methods, e.g. coupled with mass spectrometry (GC-MS)
- Dynamic scanning calorimetry (DSC)
- Transmission (TEM) and scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDS)
If you are not sure whether your question falls within our area, please do not hesitate to contact us. We will handle that for you!
