Eastman Plasticizers for PVC
Eastman 168 non-phthalate plasticizer has been safely used in PVC for generations. With proven performance as an alternative to DOP/DEHP and DINP, Eastman 168 can be used for a wide variety of flexible PVC applications. In many cases, our non-phthalate solutions can be a drop-in replacement for traditional phthalates in your manufacturing process.

ing plasticizer content. Above about 35 phr DOP, or plasticizer with comparable activity, PVC is considered exible. At 50 phr, 100% tensile modulus has dropped to about 1700 psi, and at 85 phr, about 650 psi, indicating a highly exible compound. Lower levels of a more efcient plasticizer will generate comparable data, while less
What is DEHP? Where is it used? Why is it used? | U.S. Plastic
Plasticizers are essential to make PVC flexible. PVC is naturally rigid, but plasticizers are added to make the tubing flexible and expandable while retaining its shape. DEHP is widely used because it is low cost, processes well, and has provided good end-use performance.
ROLE OF DIFFERENT PLASTICIZERS IN PVC PRODUCTS - LinkedIn
Since plasticizers are dissolved in S PVC (PVC is not dissolved in plasticizers) during mixing process, higher the porosity in PVC grain, higher is the extent of plasticizers...
- Why is DOP a good plasticizer for PVC?
- High plasticizing efficiency of DOP for PVC is attributed to DOP’s good compatibility with PVC and its high rate of diffusion in PVC, which result from the interaction between DOP and PVC molecules.
- Which plasticizer has a low plasticizing efficiency?
- Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
- Does DOP increase the thermal stability of plasticised PVC?
- The results showed that the thermal stability of plasticised PVC was improved by increasing DOP percentage, but in the same time has a reverse behavior where the LOI decreases as the DOP percentage increases. Thermal stability test at temperature 190°C and 200°C respectful. Specifications of PVC S-5070 (Ongrovil ® ) .
- Does DOP plasticizer percentage affect limiting oxygen index and thermal stability?
- The effect of DOP plasticizer percentage on limiting oxygen index and thermal stability of plasticised PVC was investigated in this paper. DOP was added PVC with various quantities (20, 30, and 50) pphr. LOI and thermal stability instruments used for estimating LOI and thermal stability of plasticised PVC as a function to DOP percentage.
- Is DOP-o-cp52 a better plasticizer than DOP?
- Both Tgs were gradually reduced with the increased addition of plasticizer. DOP-O-CP52 has almost the same plasticizing efficiency as DOP within the ratio range (from 0 to 0.3) of plasticizer to PVC, which indicated the novel DOP-like plasticizer could have the same performance as DOP in many applications.
- Is cp52 a good plasticizer for PVC?
- However, stronger interactions between plasticizer and PVC will reduce its rate of diffusion in PVC, leading to lower plasticizing efficiency. A compromise is achieved using DOP-O-CP52, yielding PVC with no migration and high plasticization. CP52 appears to be a better choice for DOP.
