trinamiX, a subsidiary of BASF SE, says that its spectrometer can now reliably differentiate between polyamide 6 (PA6) and polyamide 6.6 (PA66).

Since PA6 and PA66 have similar properties, they are used interchangeably in numerous applications and are virtually impossible to distinguish with the naked eye, the company said.

‘For many recycling companies, sorting PA6 and PA66 previously involved a cumbersome analysis process,’ said Adrian Vogel, manager at trinamiX. ‘With our new application, recycling companies can quickly determine the polyamide type and process the waste streams accordingly.’  

Plastics processing companies who use PA6 and PA66 can also perform a clean separation of PA6 and PA66 production rejects or waste, according to trinamiX. 

The trinamiX Mobile near infrared (NIR) spectrometer can also identify common plastics including polyolefins such as PE and PP, polyethylene terephthalate (PET), and engineering plastics such as acrylonitrile butadiene styrene (ABS).
