Cis-butadiene low-molecular weight rubber SKDN-N

TECHNICAL REQUIREMENTS

Rubber SKDN-N must confirm the requirements shown in table:

TECHNICAL DATA
Properties Value for grades
Dynamic viscosity at 20°C, Pa.s 700 … 860
Acid Number,mg KOH/g ≤0,3
Peroxide Number, mval/kg ≤10

THE SCOPE

Rubber SKDN-N is a stereospecific, low viscous and unsaponifiable liquid polybutadiene with a high content of 1,4-cis double bonds having the following composition:

1,4-cis double bonds approx. 75%

1,4-trans double bonds approx. 24%

1,2-vinyl double bonds approx. 1%

NG-2246, Irganox 1520, AO-300 and others are used as non-staining antioxidants.

SKDN-N PROPERTIES

Rubber SKDN-N is a viscous transparent mass without smell. It is soluble only in organic solvents at normal conditions. The rubber's density is 900-910 kg/cm3. Rubber is stable at normal conditions of use. By its effect on humans the rubber is referred to products of low hazard. Rubber is not irritative to skin and doesn't acquire cumulative effect.

APPLICATION FIELDS

Low molecular weight rubber SKDN-N takes an extraordinary place among liquid rubbers, because it can excellently replace vegetable oils. The rubber's good ability to be oxidized find wide application of SKDN-N in colors and vanishes industries for vanishes, colors, corrosion resistant compounds fabrication and electrophoresis materials production, for example, primers. Polymer oils of company "Evonik" are foreign analogues, which are used for the same purpose.

PACKAGING AND TRANSPORT

100, 200 and 216,5 dm3 steel drums on pallets or IBC by covered road transport. Guaranteed period of storage are 3 years from the manufacturing day.
