Plastic is used everywhere: in packaging, kitchenware, toys, sports equipment, cars and electronic equipment to mention just a few.
In addition to polymers, plastic can include various substances either as impurities or as intentionally added substances. These substances may migrate to the adjacent environment called the recipient. Examples of recipients are air, water, food, blood, sweat and saliva.
When the substances can be hazardous to human health or the environment, the migration risk should be assessed.
We can help you with that!
We have developed a validated migration model to calculate the extent to which specific substances will be able to migrate to and from polymer materials and into a recipient.
With this tool we can assess the most important parameters, such as the diffusion coefficient and the partition coefficient, for various combinations of substances, polymers and recipients.
Among others, we can calculate:
Two factors in particular impact migration:
With a risk assessment of substances in the plastic, we can document the possible impact of the substances on human health or the environment. This is relevant in many contexts, including:
