N-tert-Butyl-2-benzothiazolesulfenamide Usage And Synthesis
DescriptionN-tert-Butyl-2-benzothiazolesulfenamide (TBBS) is one of the essential kinds of sulfenamide vulcanization accelerator, have anti-incipient scorch and the large advantage of vulcanization rate fast two concurrently for natural rubber, styrene-butadiene rubber(SBR), cis-1,4-polybutadiene rubber, in polyisoprene rubber, be particularly useful for the furnace treated black sizing material that alkalescence is higher, variable color and pollution are slight, the alternative NOBS(N-morpholinyl benzothiaolesulfenamide having carinogenicity possible containing secondary amine), the NOBS of tire industry is replaced with CBS (CZ) or TBBS in l994 law-making stipulation by Germany.
UsesN-tert-Butyl-2-benzothiazolesulfenamide is used as an accelerator for natural and synthetic isoprene and butadiene rubbers.
