Plasticizers: Types, Uses, Classification, Selection & Regulation
A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
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.

performance, value, and durability. Firestone PVC KEE single-ply membrane formulation uses DuPont Elvaloy KEE, a solid plasticizer that bonds with the PVC to provide consistent and dependable long-term plasticizer retention, taking durability to new heights with its superior performance and exceptional value.
Uniplex | IMCD US
Uniplex 108: Useful liquid sulfonamide plasticizer with a low order of toxicity. Approved for use in food packaging applications according to 21 CFR 121.2514 and 121.2520. Uniplex 171: A solid plasticizer useful for thermosetting resins (melamine, urea, phenolic) improving workability, smooth finish, and uniform curing.
Specialty Plasticizers for Rubber/Elastomers | Hallstar
Most of the acrylics require a plasticizer to achieve low temperature performance. Many monomerics are too volatile to be of value because of the post cure requirement. Low temperature performance can be best achieved with polymerics as well as TP-759 and TegMeR 812. APPLICATIONS . O-rings; Valve stem oil deflectors; Lip seals, gaskets
- What is a solid state plasticizer?
- Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers. Binary and ternary physical mixtures were evaluated as a function of plasticizer concentration for thermal and rheological behavior.
- Which solid-state plasticizers are used in a chemistry study?
- Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers.
- How to select solid-state plasticizer?
- The selection of solid-state plasticizer should include miscibility of plasticizer in polymer as well as API and its effect on T g and η 0 of the final system. It can be summarized that when components are miscible, different techniques will lead to the consistent plasticization effect prediction.
- How effective is a plasticizer?
- The effectiveness of a plasticizer depends on its inherent properties, including its dielectric constant, viscosity, and how it interacts with other components in the electrolyte system . While EC has high conductivity and is stable at high voltages, ethylene carbonate (EC) can oxidize on the surface of high-nickel cathodes.
- Are plasticizers miscible with API and polymer?
- Based on the solubility parameter, plasticizers such as SA, GB, and PEG showed Δδ (API) and Δδ (polymer) < 7 MPa ½, and they are likely to be miscible with the API and polymer. These plasticizers are expected to form a one-phase system with the INM-EPO mixture.
- Which reagents are used in solid-state plasticizers?
- Stearic acid (SA) (Mallinckrodt) glyceryl behenate (GB) (Gattefossé, Saint-Priest, France), and polyethylene glycol (PEG) 8000 (Dow-Union Carbide) were selected as solid-state plasticizers to be investigated. All other reagents were of analytical grade.
