the hemocompatibility of artificial surfaces in extracorporeal blood circulation systems can be improved by coatings. according to the literature, heparin coatings should avoid the leaching of the plasticizer di(2-ethylhexyl) phthalate (dehp) into the blood from components made from plasticized polyvinyl chloride (pvc).
bio-based plasticizers for polyvinylchloride (pvc),natural–based pvc plasticizers increased over the last few years owing to the following advantages: 1. increase the workability. 2. low toxicity. 3. low migration. 4. good compatibility with pvc. 5. provided from renewable and biodegradable resources. 6. increase the polymer chain flexibility. 7. reduce greenhouse gas emissions.

table i. performance of plasticizers compounded to a standard modulus (0.5-mm film). study 2 took a different approach, holding the amount of plasticizer in the compound constant for all plasticizer types and allowing the hardness and modulus to vary. 2 the ingredients were mixed and then placed on a two-roll mill for 5 to10 minutes at 163°–171°c.

non-phthalate plasticizer deht preserves adequate blood,rbcs produced and stored in pvc-deht blood bag sys-tems paired with sagm or paggsm, during a 49-day storage period. the effects were compared to correspond-ing storage in pvc-dehp. secondary, we compared plasma and platelet components stored in deht or dehp, to ensure their compatibility in a future wb set. materials and methods
polyvinyl chloride (pvc) plasticized with di(2-ethylhexyl) phthalate (dehp) has been the material of choice for commercial blood containers since the mid-20th century. plasticizers are essential for material flexibility; facilitating centrifugation, sealing, transport and general handling of blood bags without risk of breakage and product loss.

this study has shown quite clearly that plasticizers, utilized in the tubing element of perfusion circuits, migrate into the priming fluid. this is the case for all plasticizers investigated in the present study. however, there are clear differences in terms of the migration rate and the time-frame of migration between the tubing types.
materials degradation in pvc medical devices, dehp leaching,at room temperature pvc is hard and brittle, thus great amounts (40-50%) of phthalate esters that act as plasticizers are added to the polymer to make it flexible and appropriate for medical use. di-(2-ethylhexyl)-phthalate (dehp) is the most widely used plasticizer in pvc medical devices.

there are two main groups of plasticizers: primary—the main plasticizer in a pvc blend, added in large quantities and highly compatible with pvc; and secondary—having limited compatibility with pvc, easily migrating, especially when used in excess and usually added to the blend to improve its properties or to reduce its costs .
