Chemical characterization
Our chemical characterization services for engineering plastics and chemicals used in their production include several advanced GPC/SEC methods, as well as NMR, FTIR, and Raman spectroscopy. Examples of popular measurements and their applications include:
Polymer characterization by NMR to identify polymers and evaluate their purity or contamination levels
Polymer characterization by py-GC-MS to determine polymer types by their decomposition products
Raman and FTIR analyses to identify specific chemical groups within the polymer structure
For molecular weight determination, we offer several GPC/SEC techniques suitable for different types of polymers. You can find out more about these analyses through the links below.
Thermal analysis
We offer several characterization techniques to ensure that engineering plastics meet application-specific criteria for thermal properties, indicating their ability to maintain a high degree of performance at low and high temperatures. The following are examples of our most commonly requested services in this area:
Differential scanning calorimetry (DSC), yielding information on transition temperatures and enthalpy changes
Thermogravimetric analysis (TGA), providing data on phase transitions, decomposition behavior, and solid-gas reactions
Thermomechanical analysis (TMA), measuring dimensional changes and mechanical properties in response to temperature variations
Dynamic mechanical analysis (DMA), determining changes in viscoelastic properties as a function of temperature and frequency of applied stress or strain
We also provide analyses with less widely available techniques, such as vacuum TGA, where thermal properties are studied under low-pressure conditions. Do not hesitate to contact our experts for more information or a tailored quote.
Electrical properties
Electrical testing is crucial when engineering plastics are used in electrical applications, such as protective casings, cable sheathing, or film capacitors. Our service selection contains the following standardized electrical tests for plastics:
Dielectric strength according to IEC 60243-1 or ASTM D149
Surface and volume resistivity according to IEC 62631-3-1 and IEC 62631-3-2
Comparative tracking index (CTI) according to IEC 60112
Electromagnetic interference (EMI) shielding effectiveness according to IEEE-299
Upon request, the dielectric strength and resistivity tests can be conducted at cryogenic or elevated temperatures.
Fire behavior
Flammability testing according to the UL 94 rating system is often required when engineering plastics are used in applications where they must exhibit a significant degree of fire resistance, such as construction products and electronic devices. We offer the following UL 94 tests for plastic flammability rating:
Horizontal burning test for HB classification of solid and cellular plastics
50 W vertical burning test for V2, V1, and V0 classifications
500 W vertical burning test for 5VB and 5VA classifications
Horizontal burning test for foamed plastics for HBF, HF-2, and HF-1 classifications
Other fire tests are also available for polymer-based construction materials and components used in specific high-risk environments, such as on trains, ships, and buses. The links below provide more information on some of these tests.
