A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Flexible samples with 0.32:1 plasticizer over PVC were selected to ensure a high migration rate of plasticizers. These results indicated that the new DOP-like plasticizer in PVC was very...
Research progress of novel bio-based plasticizers and their
Biomass renewable resources have wide range of sources and low prices, and the chemicals obtained from them have various structures, which can provide a huge platform to design novel PVC plasticizers with the aim of replacing traditional phthalate plasticizers.
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.
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.

At low plasticizer levels, the plasticizer–PVC interactions are the dominant interactions while at high plasticizer concentration ranges, plasticizer–plasticizer interactions can become more important. For a plasticizer to be effective and useful in PVC, it must contain two types of structural components, polar and apolar.
- How to choose a general-purpose plasticizer for PVC?
- While selecting a general-purpose plasticizer for PVC, the main attributes to be checked are: Among them, regulation is an important decision factor while selecting plasticizers. In recent years, there has been a lot of discussion on phthalate plasticizers. But in fact, not all phthalates are prohibited.
- 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.
- 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.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- Can PVC be a plasticizer?
- However, POSS can’t be as main plasticizer of PVC due to its limited miscibility with PVC. In order to improve compatibility of PVC and POSS systems, POSS and a little phthalates are used in PVC blends . PVC/methacryl-POSS systems containing 5 wt% DEHP appear to be transparent and homogeneous.
- Why do flexible PVC products need plasticizers?
- The properties of flexible PVC products significantly change with addition of plasticizers, such as reduction of the glass transition temperature (Tg) and tensile strength, while elongation will increase, which make PVC change from hard and brittle to flexible, thus greatly expand its application [, , ].
