SKI-3S 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 mixture of two non-staining antioxidants.
Content of cis-1,4-units, min: 96 %.
CAS: # 9003-31-0
Application: for manufacture of auto tyres for lining of side-frames as well as coloured bicycle and motorcycle tyres, and also in manufacture of colored rubber goods, non-coloured industrial rubber goods used in manufacturing industry (rubber hoses, tubes, shoe soles). Rubber should not contain any foreign impurities and must meet the following requirements

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.
