Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers are one of the commonly used additives in adhesives and sealants formulations. They improve the performance of adhesives by creating much-needed flexibility, optimizing viscosity, toughness, set time functionality, impact resistance, and even adhesion.
Plasticizers for PVC | POLYNT
Plasticizers trimellitates: they are characterized by an excellent flexibility at low temperatures and high resistance to higher temperatures; they are molecules primarily used in the production of electrical circuit components, wiring cables, car interiors and machinery components used in the medical and scientific field.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
To show plasticity, PVC must be heated to a certain temperature, which is challenging for PVC moulding products. Therefore, in PVC materials, plasticization is necessary to reduce softening...
Alternatives to LMW Phthalate Plasticizers for PVC: Selection
Recorded on Mar 2, 2025. Formulation. (62 ratings) Implement a well-defined methodology to select the right alternatives for phthalates (low-molecular weight) that cater to the stringent health & environmental regulations. Paul Daniels will discuss different types of plasticizers (vegetable oil derivates, citrate esters, benzoate/dibenzoate
- How to choose a plasticizer?
- be blended together. This imparts the best attributes of both classes, resulting in optimal performance in the end-use application.The best way to select a plasticizer is to first determine what the critical performance parameters are for the end product application. Normally, one can determine the two or three most necessary properties in their
- Should you mix plasticizers with PVC?
- Mixing plasticizers with PVC and processing the blend need to be cost-effective as well. Long shelf life and durability over harsh aging conditions (UV resistance, migration and extraction resistance) are key attributes to consider when selecting a plasticizer.
- 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.
- What are the different types of plasticizers?
- 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 . Figure 1.
- 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.
- What is the role of plasticizers in PVC processing?
- Their major function is to impart flexibility and workability of the resin. Plasticizers play an important role in the processing of PVC by: They decrease the processing temperature, the melt viscosity while improving filler and pigment dispersion .
