Webb10 apr. 2014 · As for the above, the surface hardness is lower for HIPS and you could detect that with a Shore Hardness meter. 3. FTIR spectrocopy will see the butadiene if there's impact modifier there. 4. NMR spectroscopy would work. 5. Gloss measurements, especially at low angles like 20 degrees can reveal the presence of rubber. WebbFourier Transform Infrared spectroscopy (FTIR). The analysis of mechanical properties showed a decrease in elongation at break and impact strength. FTIR analysis indicated heterogeneous distribution of the blend in injected pieces and SEM micrographs show heterogeneous distribution of both phase (ABS and HIPS).
WebbFTIR analysis, on the other hand, successfully identified both blanks and sampled filters as either uniform or non-uniform. The filter classification derived from the FTIR study enabled each filter to be assigned to the correct HIPS calibration such that no sample data was lost. WebbFTIR study enabled each filter to be assigned to the correct HIPS calibration such that no sample data was lost. FTIR calibrations were similarly built using the FTIR-derived filter …
