Recycling of Polymers and Plastics

If medium sized and large polymer parts are disposed of (e.g. automotive components), it is important to sort them by plastic type for recycling. An example would be thermoplastics such as polyamides, which can be recycled mechanically by thermal shaping, or chemically by acid- or base-catalyzed hydrolytic depolymerization.

所以在这种情况下,为了获得一个acceptable recycled product, different polyamides must be reliably differentiated, since the quality of the new product depends directly on the purity of the recycled material. FT-IR spectroscopy offers an inexpensive, on-site and easy-to-use approach to perform chemical analysis of polymers and plastics.

The road to new plastic products is long for recycled polymers. This means that the material passes through many hands during sorting, typification, transport, repurposing and final production.

For processors, manufacturers and end customers, it is therefore very important to check the purity of supplied recycled materials.

Infrared spectroscopy allows qualitative and quantitative to avoid damages and optimize recycling processes. It analyzes polymers of any type, dimension and size, e.g. molten films, shred or pellets .
