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. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
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.
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
Plasticizer composition, resin composition and method
The present invention relates to a plasticizer composition, a resin composition and a method for preparing thereof. The present invention can provide a plasticizer composition, which can improve properties required to the plasticizer composition contained in a vinyl chloride-based resin composition, such as plasticizing efficiency, tensile retention and elongation retention, volatile loss, and
CN103664196A - Composite plasticizer composition - Google
The invention discloses a composite plasticizer composition, which is prepared from the following components in parts by weight: 20-40 parts of polyvinyl chloride, 10-15 parts of glycerol...
- How do you calculate plasticization efficiency?
- Primarily, plasticization efficiency is a first-order process and can be expressed as A = A 0 e − K [c] plasticizer where A = measured parameter, A 0 = A when plasticizer concentration is 0, K = rate constant, and [c] plasticizer = plasticizer concentration.
- 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.

- 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 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.
- 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.
