New Plasticizer Chemistry for PVC Excels in Cold & Heat
New Flexidone plasticizers ensure greater flexibility at lower temperatures than conventional alternatives such as di-octyl adipate or DINP. It’s rare that an entirely new plasticizer chemistry comes along for flexible PVC—especially when it comes with an established health and safety record.
Synthesis of novel plasticizer ester end-capped oligomeric lactic acid
The plasticizing performance of EOLs in PVC was tested and compared with those of commercial environmental plasticizers acetyl tributyl citrate (ATBC) and di-2-ethylhexyl terephthalate (DOTP). According to the results of tensile tests, the elongation at break of PVC plasticized by 50 phr EOLs reached 725.5%, indicating its superior mechanical properties.
Synthesis and properties of a bio-based PVC plasticizer derived
The results show that the PVC films plasticized using ALHD have better organic solvent resistance and food mimic migration stability than ATBC. After 24 hours of extraction in cyclohexane and petroleum ether, the weight loss of PVC sample S5 plasticized using pure ALHD was reduced by 83.6% and 77.5%, respectively, compared to that of PVC sample S1 plasticized with pure ATBC.
Plasticizer - an overview | ScienceDirect Topics
Plasticizer loss causes plasticized PVC to shrink and become stiff. This can occur quickly at room temperature with low-molecular-weight plasticizers. As the molecular weight of plasticizer is increased, permanence at room or elevated temperature improves. Volatile loss from plasticized PVC is subject to two major controls governing transfer to
- Can Plasticizers improve the mechanical properties of poly (vinyl chloride)?
- Multiple requests from the same IP address are counted as one view. This paper reviews the current trends in replacing commonly used plasticizers in poly (vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhancement in mechanical properties and better plasticizing efficiency.
- Does polyvinyl chloride (PVC) need a heat stabilizer?
- The development of a heat stabilizer with good thermal stability, plasticizing performance, and migration resistance for polyvinyl chloride (PVC) is still a notable challenge.
- Does a mixture of Plasticizers improve the mechanical properties of PVC?
- Moreover, the mechanical properties were improved when a mixture of plasticizers was applied in PVC blends, whereas a blend with pure SOHE showed worse mechanical properties (lower elongation at break and higher tensile strength) than DOP.
- Does covalent bonding affect plasticization efficiency?
- Covalent bonding of plasticizer molecules and PVC chains is an effective way to suppress the migration of a plasticizer from plastics. Although they not able to exhibit good plasticization efficiency, new internal plasticizers are still developed. There are several studies describing internal plasticizers and this issue is still being investigated.
- Is PVC a good plasticizer?
- Thermal stability studies showed that PVC blends with HPGs were more stable (exhibiting higher onset temperature values on TGA curves) than samples with DEHP. A great number of ether and ester groups in a plasticizer molecule provide donor-acceptor interactions with PVC, resulting in an excellent migration resistance.
- Why do we use heat stabilizers in PVC films?
- In addition, heat stabilizers can also act as a plasticizer to increase the movement of the molecular chain. If PVC chains can easily adjust the conformation, it can convert the internal heat energy into kinetic energy, which makes the plasticized PVC film with superior thermal stability.
