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.
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.
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...
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.
Blending Optimization of Non-Dioctyl Phthalate Plasticized
This study evaluates the dry-blending cycle time of a suspension grade PVC formulated with various non-DOP plasticizers, di- (2-ethylhexyl) terephthalate (DEHT or DOTP), tris (2-ethylhexyl)...
- 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.
- 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 is a polymeric plasticizer?
- Polymeric plasticizers are typically made from aliphatic dibasic acids such as adipic acid and diols. They are primarily valued for their permanence. These plasticizers are generally classified as polyesters, not adipates. Many have low solvency for PVC and high viscosity. Both these factors can make processing f-PVC compounds difficult.
- 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 .
- Does a PVC plasticizer need to be labeled in California?
- If it can be demonstrated that a flexible PVC product containing (Proposition 65 listed) DEHP plasticizer, for example, cannot expose a consumer to more than the maximum acceptable daily limit of DEHP (established by the state of California), no labeling is required in California.
- Which plasticizer has the lowest volatility?
- The Red Curve Shows Volatility, the Blue Curve Compatibility, and the Green Curve Shows the Solubility Temperature. Plasticizers like DINP and DIDP would typically offer the lowest volatility among the general-purpose plasticizers and good retained mechanical properties after aging.
