PA6 and PA66 belong to the most sought-after engineering plastics.
trinamiX, a wholly owned subsidiary of BASF SE, now supports the reliable differentiation between polyamide 6 (PA6) and polyamide 6.6 (PA66) with its Mobile Near-Infrared Spectroscopy Solution.
Within seconds, plastic waste from the two polyamides can be sorted using a handy measuring device as part of trinamiX’s solution. With this new application, trinamiX is responding to customer wishes and expands its broad offering for plastic sorting.
PA6 and PA66 belong to the most sought-after engineering plastics. Thanks to their robustness, they are suitable for a wide range of applications – from fishing nets to resilient components. Since PA6 and PA66 have similar properties, they are used interchangeably in numerous applications – and it is virtually impossible to distinguish them with the naked eye.
At the same time, the separation of PA6 and PA66 has gained traction in recent years in light of growing requirements within the recycling industry. As a result, the production of high-quality single-grade plastic recyclates - including PA6 and PA66 - is becoming increasingly lucrative.
"For many recycling companies, sorting PA6 and PA66 previously involved a cumbersome analysis process – and, therefore, proved often times neither profitable nor feasible,” explains Adrian Vogel, Manager Sales and Business Development Spectroscopy Solutions at trinamiX. "With our new application, recycling companies can quickly determine the polyamide type and process the waste streams accordingly."
Besides the recycling industry, plastics processing companies who rely on PA6 and PA66 in their products also benefit from trinamiX's new application. They are now enabled to perform a clean separation of PA6 and PA66 production rejects or waste. In-house recycling processes can thus be geared towards an optimized and more efficient use of valuable resources.
In addition to distinguishing PA6 and PA66, trinamiX Mobile NIR Spectroscopy Solution can already identify all common plastics - from classic polyolefins such as PE and PP, to PET (polyethylene terephthalate) and engineering plastics such as ABS (acrylonitrile butadiene styrene).
