Equipment for testing the Gas Permeability of thermoplastic foils Lyssy Dansensor L100-5000
This instrument is suited for gas permeability testing of thermoplastic based foils, sheets and plates. Reproducibility 1.5 % Standards: meets ASTM D 1434, ISO 2556 Environment temperature: 5 – 40°C
Atomic force microscope Multimode 8
Atomic force microscope is designed to the characterization of polymers and polymer nanocomposites surface. AFM investigations provide information on the surface topography, adhesion, morphology (crystalline phase, nanoparticles dispersion) and roughness. PFQNM can generate material property maps at nanolevel.
Nanomechanical testing instrument Hysitron TriboIndenter Premier
The TriboIndenter (TI) Premier makes nanoscale mechanical and tribological characterization simple and consistent. This dedicated system provides a variety of standard nanoscale characterization techniques with unparalleled accuracy and precision. The TI Premier comes with in situ SPM imaging capability and capacitive transducer technology, making the system applicable to the widest range of materials and devices. Motorized staging, top-down color optics, anti-vibration system, environmental enclosure, control software, and fast digital electronics decrease time to results and ease instrument use. The TI Premier offers automated testing routines for increased testing throughput and minimized operator interaction.
Equipment for the measurement of interfacial properties CAM200
CAM 200 allows the evaluation of hydrophilicity/hydrophobicity of the materials surface, surface tension and interfacial adhesion of polymer blends and composites and the effectiveness of the surface treatments of polymers or organic/inorganic (nano) fillers. For the measurement of the contact angle and interfacial/surface tension, the shape of the droplet is analyzed using the captured images.
