Our experts provide insight and in-depth identification and analysis of the most common recycled plastics such as PET, textile materials, buttons, by NMR, GPC, ICP and XRF.
Recycled plastic analysis is a growing concern, with many companies eager to learn about the nature of plastic, discover whether it has been recycled before and, if so, to what percentage. In addition, analyzes are made on the purity of the material, in particular the presence and molecular weight of heavy metals.
Our experts gain insight into the composition of recycled materials using a range of techniques such as nuclear magnetic resonance (NMR), GPC, ICP and XRF, either recycled or as a final product, especially in the manufacture of polyester-based materials.
Our NMR team has many years of expertise in the fields of characterization, composition and contamination of polymers and plastics that have an impact on products such as plastic bottles, films for sealing food packaging and other materials. Other mechanical / physical properties can also be measured.
Accordingly, EUROLAB determines the recycling rate and RECYCLE makes tests.
A selection of common polymers analyzed routinely include:
- Polyesters - including PET and PEN
- Polyolefins - HDPE, LDPE, LLDPE
- Vinyl based polymers - PVC
- Styrene-based polymers - polystyrene
- Textile Accessories
- PP Used in Food Packaging
- General HDPE Products
Polyethylene terephthalate (PET) and recycled PET Packaging Testing
Physical and chemical laboratory analyzes and properties determination tests on PET and recycled PET materials are as follows.
Polyethylene terephthalate (PET) and recycled PET (rPET) materials are known for their durability and versatility and are analyzed for many reasons, for example, to verify whether the material has previously been recycled and if so, how many times it has been verified. To discover molecular weight and purity, for example the presence of heavy metals
EUROLAB chemists have years of experience in the analysis of PET packaging materials using a wide variety of analytical and physical testing techniques. Our expert team can support you in troubleshooting, process optimization and problem solving activities related to the processing of your PET materials.
Our experts adopt a range of techniques such as nuclear magnetic resonance (NMR), GPC, ICP and XRF to determine the composition of materials such as PET as part of the recycled plastic analysis.
