SKI-3D cis-isoprene synthetic rubber is cis-1,4-polyisoprene obtained by polymerization of isoprene in solution using stereospecific catalyst based on titanium. The rubber is stabilized by staining antioxidant.
Content of cis-1,4-units, min: 96 %.
CAS: # 9003-31-0
Application: for manufacture of cable products, high-voltage flexible cables with rubber insulation, operating at temperature between -40 and +50 оC, used to power dredges and other surface structures. This rubber is also used in the production of electroinsulating rubber goods. Rubber should not contain any foreign impurities and must meet the following requirements
Appearance: briquettes (bales)
Weight: 30.0+/-1.0 kg
Colour: from brown to bluish-green, black
Specific gravity: 0.91-0.92 g/cm3
* – specified in the certificate of quality.
** – non-rejectable.
Preparation of rubber mixes is carried out in accordance with ASTM D 3403-07, mixing – according to С method (on the roll mills). Roll mills are prepared according to ASTM D 3182-07. Vulcanization characteristics are determined according to ASTM D 5289 using an MDR 2000 rheometer (flow meter).
Wait time for rubber mix before testing is 2-6 hours.
