Preparation and characterization of polyurethane plasticizer
Polyurethanes (PU) have numerous applications in the coating industries because of their mechanical strength, excellent abrasion resistance, toughness, low temperature flexibility, chemical and corrosion resistance [3]. For printing inks, the primary binder is usually nitrocellulose.
Reactive Plasticizer - an overview | ScienceDirect Topics
Reactive plasticizer reduces the amount of potential volatiles in the final product and helps in reduction of viscosity and thus improves processability. On the other hand, reactive plasticizer crosslinks material which thus needs non-reactive plasticizer to increase its flexibility.2
Plasticizers: Types, Uses, Classification, Selection & Regulation
Due to its low cost and generally good performance, DEHP is widely employed as a plasticizer in manufacturing articles made of PVC. Melting point: 50°C Boiling point: 250 - 257°C at 0.5 kPa Structure of DEHP DEHP offers good gelling, satisfactory electrical properties and helps to produce highly elastic compounds with reasonable cold strength.
Reactive Energetic Plasticizers for Energetic Polyurethane
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

Reactive energetic plasticizers (REPs) coupled with hydroxy-telechelic poly (glycidyl azide-co-tetrahydrofuran) (PGT)-based energetic polyurethane (PU) binders for use in solid propellants...
- Why do you need a plasticizer for polyurethane?
- Our plasticizers help regulate the properties in polyurethane, making polyurethane more more pliable and easy to extrude so it can be used in many more applications. SANFLEX LBU-25 is an urethane modified polyether type plasticizer with excellent blooming out resistance.
- Which plasticizers are used for polyurethane based sealants?
- SANFLEX products are widely used as plasticizers for polyurethane-based sealants. Plasticizers are used in many products. And Sanyo Chemical America plasticizers are making polyurethane more versatile. Sanyo Chemical America makes a variety of plasticizers with an excellent anti-migration property.
- Does the plasticizer affect the thermo-mechanical properties of a polyurethane network?
- The effect of the plasticizer (BuNENA) on the thermo-mechanical properties of the polyurethane network was investigated using a dynamic mechanical analysis (DMA) and tensile test. Tensile strength and modulus of the polyurethane are decreased by increasing of the BuNENA.
- Does the Bunena plasticizer affect the polyurethane network?
- The mechanical properties effect of the BuNENA plasticizer on the polyurethane network was investigated using dynamic mechanical analysis as well as the tensile test.
- Can polyurethane plasticizer be used for printing ink?
- The results indicated that polyurethane plasticizer were prepared successfully by the partial substitution of petroleum polyols with vegetables oil polyols, castor oil and palm olien, given a very comparable mechanical, optical, thermal and freeze properties. Table 5. Properties of printing inks with standard and prepared polyurethane plasticizer.
- Can polyglycidyl nitrate-based energetic polyurethane network improve thermal and mechanical properties?
- In this research to improve the thermal and mechanical properties of polyglycidyl nitrate (PGN)-based energetic polyurethane network was used a novel flexible chain triblock copolymer based on polypropylene glycol–poly glycidyl nitrate–polypropylene glycol (PPG–PGN–PPG).
