Help Improve Predictive Models for Recyclates
Contribute Training Data to Proteus® Now Quantify
Recycling streams are inherently complex.
They consist of a wide variety of polymers, additives, and unknown contaminants that often vary significantly from batch to batch. This complexity poses a significant challenge to the polymer recycling industry, making reliable material identification and contamination detection difficult.
To address this challenge, Proteus® Now Quantify is being developed to improve the detection of contaminations and the classification of materials for recycled polymers. Expanding and refining the underlying material database is key to achieving this objective.
To build reliable machine learning models, we require high-quality, standardized NETZSCH DSC training data from real industrial compounds. We are specifically looking for compounded materials based on virgin polymers that realistically represent typical contamination scenarios found in recycling streams. This enables us to create controlled, well-defined datasets for robust model training.
Your contribution will help increase accuracy, robustness, and industrial applicability of predictions, thereby supporting improved recyclate evaluation in the polymer industry. Dry blends and actual recyclates are not suitable.
“Help us make Proteus® Now Quantify even more powerful and benefit directly from improved analysis results. By sharing standardized NETZSCH DSC training data, you help make the AI models more accurate, robust, and better suited for real industrial recyclates. The more diverse the dataset, the more accurate and valuable the model becomes for everyone.”
Why Standardization Matters
Machine learning models are only as good as the data they are trained on. For Quantify to deliver reliable predictions, the following conditions must be met:
- Measurement conditions must be identical
- Thermal histories must be comparable
- Curve shapes must reflect true compound behavior
Even small deviations in DSC parameters influence the peak shape, enthalpy, and CrystallizationCrystallization is the physical process of hardening during the formation and growth of crystals. During this process, heat of crystallization is released.crystallization behavior, which directly affects the model performance.
Therefore, only measurements conducted under the defined Quantify standard can be used for training.
Quantify Measurement Checklist (Mandatory for Training Data)
Method Parameters
- Sample weight: 10 ± 1 mg
- Heating rate: 10 K/min
- Cooling rate: 10 K/min
- Atmosphere: Nitrogen (default gas flows)
