Spectrophotometric characterization of plasticizer migration
PVC > TBTM-PVC ≈ TOTM-PVC ≈ DOA-PVC > BIO-PVC > DOTP-PVC for 80 phr. These show that BIO, DOA and DOTP have stronger interaction with PVC therefore they have higher compability with PVC. The common features of these plasticizers are having linear conformation and similar molecular weights.

A Comparison of Plasticizers for Use in Flexible Vinyl
In Study 1, plasticizer levels were adjusted to create molded compounds that were at a constant or standard 100% modulus value. 1 The compounding procedure was designed as follows: ingredients were mixed well by spatula and then placed on a two-roll, 6 x 13-in. mill heated to between 140° and 177°C, depending on the compound, for 5 minutes from the point that the material fluxed.
- What is DOA plasticizer?
- If a country is not listed for a region, contact Eastman for further information. DOA Plasticizer is a light colored, oily liquid generally used as a plasticizer for PVC. It can be used alone or blended with other plasticizers.
- Can DOA be used as auxiliary plasticizer?
- However, due to the poor migration resistance of cold-resistant plasticizer DOA, it can only be used in PVC as an auxiliary plasticizer. Therefore, it is usually used in conjunction with DOP and DOA, the proportion of DOA does not exceed 20 wt%, to impart cold resistance to PVC.
- Does DOP elongation increase the tensile strength of PVC films?
- Elongation at break values of PVC films with DOP and different hyperbranched plasticizers were comparable and the tensile strength was slightly higher for new plasticizers than for DOP. The new compounds were characterized with a good thermal stability and improved plasticizer migration resistance.
- What is Eastman DOA plasticizer?
- Home ... Eastman™ DOA plasticizer (Bis (2-Ethylhexyl) Adipate) is a light colored, oily liquid generally used as a plasticizer for PVC. It can be used alone or blended with other plasticizers, such as DOP or DOTP.
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
- Is hexane a better plasticizer than DOTP?
- A volatility test showed lower weight loss of the new plasticizers than those observed for DOTP, which is obvious due to the higher molecular weight of those novel plasticizers. The studied plasticizers in most cases exhibited leaching resistance like DOTP; however, in hexane this resistance was much better than for DOTP.
