Palamoll 654
Medium viscosity polymeric plasticizer for PVC that has a good resistance to oils, fats and water. Good compatibility and thermal stability. It has only a slight tendency to migrate into plastics.
Performance assessment of polyvinyl chloride films plasticized with
PVC films were tested for the determination of migration stability of plasticizer in different solvents for 72 h and obtained results are represented in Fig. S9. PVC film plasticized with DOP (PVC A) exhibits maximum migration in each of the solvent. The migration is decreased as the concentration of ECLO is increased.
Recent Attempts in the Design of Efficient PVC Plasticizers with
The experimental results showing the performance of PVC plasticized compounds described in this section are collected in Table 2, which contains information about the examined primary and secondary plasticizers, their content and ration in PVC blends and, if available, several results of mechanical tests, thermal properties (glass transition temperature) and stability in the sense of

VESTINOL 9 DINP is a very cost-effective, general-purpose plasticizer very useful in soft PVC formulations with a broad processing temperature window. ELATUR DPT (DiPentylTerephthalate) plasticizer has very low Volatile Organic Compound (VOC) residue build-up, has a low viscosity, and is fast fusing upon gelation.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates. They are made from aliphatic dibasic acids such as adipic acid and alcohols.
- Does plasticizer improve the thermal stability of PVC?
- It is obvious that the addition of plasticizer significantly improves the thermal stability of PVC, which should be attributed to the good thermal stability of the ester group. PEE has a macromolecular structure, and the strong intermolecular interaction further improves its thermal stability, resulting in a better improvement effect than DOP.
- Why is plastic a good stabilizer for PVC?
- In particular, the value of A NT for samples m5 and m20 is even lower than that measured for ESBO, which is usually considered as an efficient stabilizer for PVC. Therefore, PLACARD plays both roles in soft PVC, plasticizer and thermal and UV stabilizer, limiting the oxidation of PVC. Fig. 6.
- Can plasticizer improve soft PVC durability and recyclability?
- Therefore, the results highlight that PLACARD plasticizer can also act as an efficient thermal and UV stabilizer, which could increase soft PVC durability and recyclability, and contribute to a reduction of the amount of thermal and UV stabilizers, with additional relevant effects on the toxicological and environmental impact of soft PVC. 1.
- How stable is unplasticized PVC?
- Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied. Table 3 offers a comparison of the PVC samples where the temperatures at which samples lost 10% of their initial weights have been reported.
- Is PVC plasticized by a plasticizer better than a commercial plasticizer?
- The values of A N,T reported in Fig. 6 clearly show that for any thermal or UV treatment, PVC plasticized by PLACARD is characterized by lower degradation compared to PVC plasticized by the commercial plasticizers.
- What makes a good plasticizer?
- A good plasticizer must blend uniformly with the PVC matrix, ensuring that it does not phase-separate or lead to inconsistency in the material properties. An effective means to evaluate compatibility is through the analysis of: Solubility: The plasticizer should dissolve in PVC without forming precipitates.
