Novel ceramic processing method for substitution of toxic
some initial rough screenings of suitable systems necessary. It was decided to use a two component plasticizer system with a PEG as co-plasticiser. The use of a co-plasticiser can be desirable as different classes of plasticisers acts differently and induce slightly different behaviours to the final green tape [19] and [20].
Selection of Solid-State Plasticizers as Processing Aids
The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to assess their effectiveness as processing aids for HME process.
US Patent Application for Co-Plasticizer Systems Patent
Co-Plasticizer Systems Nov 20, 2008 Compositions based on slow fusing cyclohexanecarboxylic acid esters and at least one fast fusing plasticizer are useful as plasticizers for plasticizable polymers, particularly PVC.

Bioplasticizer - an overview | ScienceDirect Topics
24.14 Other Plasticizers. This category includes a variety of different plasticizers including polyol esters, nonepoxy bioplasticizers, and miscellaneous plasticizers. In 2005, Danisco introduced their new bioplasticizer, Soft-n-Safe (SNS). This plasticizer is based on castor oil, where the oil is hydrogenated, then transesterified, and
WO2009085453A2 - Co-plasticizer systems - Google Patents
[0013] The present inventor has surprisingly discovered that the fusion characteristics of cyclohexanecarboxylic acid esters in polymer systems are improved by adding, as co- plasticizer, a non-phthalate fast fusing plasticizer; this improves the processability of the flexible PVC material while maintaining the advantages associated with the
- 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.
- Are plasticizers effective as processing aids for 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 assess their effectiveness as processing aids for HME process.
- 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.
- What plasticizers are used in hot-melt extruded systems?
- Although commonly used pharmaceutical plasticizers such as triacetin, 4 citrate esters, 2, 5 and lower molecular weight polyethylene glycols 2, 3, 4 have been investigated in hot-melt extruded systems, almost all of them are liquid.
- Do plasticizers affect HME process and product performance?
- Although various studies have demonstrated the effect of plasticizers on HME process and product performance, 21, 22, 23, 24, 25 no single study has investigated the systematic approach for selecting a suitable plasticizer.
