Product Description
Bis(2-ethylhexyl)sebacate
Executive standard: GJB l967-94
English name: Bis(2-ethylhexyl)sebacate
English another name: Dicotyl Sebacate
English abbreviation: DOS
CAS RN: 122-62-3
Physical chemical properties:
Molecule formula: C26H5004
Molecule weight: 426.68
Melting point: -67 degree C
Boiling point: 212 degree C 1 mmHg
Specific gravity: 0.914
Flash point: 215 degree C
Solubility:
Undissolved in water, dissolved in acetone, ether, ethanol.
Refractive index: 1.450-1.455
Stability and reactivity:
It's stable in normal temperature and pressure, but it will burn when meeting with any strong oxidant.
Uses:
The product is used as the plasticizer for solid propellants and their cladding layers, and also as the cold-resistant plasticizer for other polymers. It can improve the mechanical properties of solid propellant, decrease the Tg and increase the percentage elongation of solid propellant at low temperature. Also, it can decrease the viscosity of propellant paste, and so increase its' fluidity and afford the composite solid propellant with good processing performance. The dosage is 10%~40% weight to the binder.
Package:
It's packed in the closed metal bucket of 200 liters, net weight 180 kg/drum.
