Synthesis and Characterization of Reactive Energetic Plasticizers
Two reactive energetic plasticizers showed better plasticizing performance than commercial energetic plasticizers. In the reactivity point of view, 3- ( (2,2-dinitropropoxy)methoxy)prop-1-yne exhibited higher Click reactivity than 4- ( (2,2-dinitropropoxy)methoxy)but-1-yne. Two synthesized plasticizers were found to fulfill the requirements for

Eastman Plasticizers for Polyurethanes
Benzoflex 9-88 is a high solvating benzoate ester plasticizer that can be used in a wide variety of polymer systems and applications. Its diverse uses include resilient flooring, adhesives, caulks, and sealants. Benzoflex 9-88 SG is recommended for cast urethane applications that require minimum cure interference and maximum compatibility.
Reactive Energetic Plasticizers for Energetic Polyurethane Binders
Reactive energetic plasticizers (REPs) for use in glycidyl azido polymer (GAP) based polyurethane (PU) energetic binders were investigated. These REPs consisted of an activated terminal alkyne group that was expected to give rise to Huisgen azide-alkyne 1,3-dipolar cycloaddition within the specific pot life for a PU formulation to prevent the migration of plasticizers, and with a gem-dinitro
Modifying Expectations: Novel Urethane Modifiers Outperform Traditional
The modifiers and plasticizers were screened in two common polyurethane systems: (1) a generic 2-K thermoplastic formulation based on a polyester polyol and MDI, and (2) a room-temperature, moisture-cured thermoset MDI-polyether polyol (2000 MW) system.
- What is a reactive plasticizer?
- Learn more. This review is about the reactive plasticizer. Plasticizers are small molecules with low molecular weight. These compounds typically have an esteric structure. The plasticizers reduce the glass transition temperature, and the viscosity of the polymer also enhances the flexibility and processability of polymer materials.
- Which plasticizers are used in urea & melamine-formaldehyde resins?
- Conventional monomeric plasticizers may be used with urea- and melamine-formaldehyde resins. Phosphates improve gloss, flexibility, flow properties, and flame resistance. Sulfonamides are reactive plasticizers with aminoplasts, imparting improved adhesion and impact resistance.
- Are reactive plasticizers used in polymerization and article formation processes?
- Reactive plasticizers are used in polymerization and article formation processes occur either sequentially or simultaneously. Anna Wypych, in Databook of Plasticizers (Second Edition), 2017 GEORGE WYPYCH, ... MAKAROVA A. MARINA, in Handbook of Plasticizers (Third Edition), 2017 diethylene glycol dibenzoate and dimethyl phthalate in membranes 1
- What is a nonreactive plasticizer?
- Nonreactive plasticizers, such as phthalates or phosphates at 25 phr, can reduce viscosity about one order of magnitude. On curing, the final resin is softer with poorer impact strength and poorer extraction resistance. Plasticizers allow higher filler loadings for epoxy resins.
- What is the difference between bone/polyurethane composite and plasticizer?
- M. BELTRAN, in Handbook of Plasticizers (Third Edition), 2017 Bone/polyurethane composite contains general plasticizer, which is selected to produce product moldable at lower temperature and make liquid composite workable. 1,3 Polyurethane is made out of biodegradable components but plasticizer can be general non-reactive plasticizer.1,3
- What is a stain-resistant plasticizer?
- Tailor-made blends have been offered as stain-resistant plasticizers for flooring. Used in a variety of primarily vinyl materials such as vinyl resins and films, but also in some cellulose derivatives. Citrates lack the permanency offered by the high phthalates, for a much higher cost.
