New oligoether plasticizers for poly(ethylene oxide)-based solid
For NOE plasticizers, the potential was anodically scanned from 2.0 to maximum 5.0 V versus Li/Li + at a scan rate of 10 mV/s. The thermal stability of SPE films has been tested by Mettler thermogravimetric analyzer (TGA).
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most commonly used phthalate plasticizers include: DEHP: Low molecular weight ortho-phthalate. Still the world’s most widely used PVC plasticizer DINP, DIDP: High molecular weight ortho-phthalates Aliphatic dibasic acid Esters – These include chemicals such as glutarates, adipates, azelates and sebacates.
Selection of Solid-State Plasticizers as Processing Aids
The objective of the study was to select solid-state plasticizers for hot-melt extrusion (HME) process. The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to asses

A review on viscoelastic behaviour of plasticizers in ap/al/htpb based
The most common plasticizer type used for solid composite propellant applications is ester. The advantages of using ester, as mentioned by Cadogan and Howick [36], are: It has low viscosity and is compatible with hydroxyl group binder. Exhibits superior high-temperature performance.
- 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.
- What makes a good plasticizer?
- In the context of HME, plasticizers are selected for their ability to lower processing temperatures and reduce melt viscosity [ 38 ]. Some additional requirements for a good plasticizer include low volatility, temperature stability, and compatibility [ 39 ].
- 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.
- Do Plasticizers improve formulation performance and stability?
- Although these plasticizers are effective as processing aid for HME, the effect of these plasticizers on formulation performance and stability is of utmost interest for the development of stabilized amorphous formulations.

- 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 do plasticizers affect the thermal stability of extrudates?
- The addition of a plasticizer will decrease the polymer Tg due to intermolecular interaction with the polymeric chains allowing for lower processing temperatures. Lowering the polymer Tg with plasticizers, therefore, facilitates thermal stability of the composite materials. For comparison, extrudates were prepared with and without the surfactants.
