With the TEGO Sorb® additives, Evonik has developed a plant-based material that counteracts the development of odors even in low concentrations. The material works in accordance with the lock and key principle. Odors are not merely masked, instead TEGO Sorb® irreversibly binds the odor-causin g molecules to each other. This works best for nitrogen or sulfur-based odors.
In many formulations, the addition of just a minimal percentage by volume of TEGO Sorb® to the total mass is usually enough to achieve permanent improvement. This enables recycling manufacturers to use a higher percentage of recycled materials making their products even more sustainable.
In addition to odor blockers, Evonik supplies many other useful additives, such as anti-foaming agents or wetting agents. These products help to ensure optimal cleaning and separation of the plastic flakes in the recycling process, and enable to remove the paper labels that have been attached to plastics with adhesives more easily.
High-performance plastics contribute to the efficient use of resources as they help to reduce weight without affecting mechanical, optical or haptic characteristics. However, not all questions on the sustainable use and the recycling of such plastics have been fully answered yet. This is where Evonik comes in; we work intensively to develop strategies and solutions on the key topics of the plastics industry.
