Plasticizer migration in medical devices

Picture1In general plasticizers can migrate out of PVC causing health concerns. In sensible applications therefore OXEA would recommend using plasticizers which show the least migration. This is the main reason TOTM is replacing DOP in some medical applications.
In medical devices not only PVC is used, also ABS, acrylic, Polycarbonate and Polystyrene are being used.
Teknor Apex did research if the potential migration of plasticizers could negatively impact the performance of these materials.
According to the study any potential migration can lead to softening, cracking and other defects in the non-PVC material.
Only TOTM was recommended for contact with the other materials.
