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.
Selection of Solid-State Plasticizers as Processing Aids
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.
Uniplex 512 | Hallstar Industrial
General Properties Uniplex 512 is a low melting waxy solid plasticizer. This solid dibenzoate has low volatility, a good ultraviolet light stability and is compatible with several polymers. The product is used as thermoplastic processing aid, as an effective plasticizer for coatings application, and as a cleaner for adhesives. Applications
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture.
Citric acid as a solid-state plasticizer for Eudragit RS PO
The use of solid-state plasticizers for the hot-melt extrusion of pharmaceutical dosage forms has been shown to be beneficial compared with liquid plasticizers. The purpose of this study was to determine the suitability of citric acid (CA) as a solid plasticizer for the preparation of Eudragit RS PO extended-release matrix systems by a melt
- 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.
- 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.
- What is a uniplex TM plasticizer?
- The Uniplex ™ family of plasticizers is based on a wide range of chemistries which are suitable for a variety of applications, including benzoates, citrates, adipates, sebacates, flame retardants and specialty phthalates. Butyl Benzoate acts as a plasticizer and solvent for cellulosic esters and ethers, as well as a carrier in AgChem applications.
