2,2'-Dithiobisbenzothiazole (DMTS)
2,2'-Dithiobisbenzothiazole (DMTS) is a sulfur-containing heterocyclic compound featuring a benzothiazole ring system. It is a separate chemically defined compound used as a rubber accelerator.
2-Mercaptobenzothiazole Industrial Grade 98%
High-purity industrial grade 2-Mercaptobenzothiazole at 98% minimum assay, qualifying as a chemically defined compound under this tariff item. Used in tire manufacturing and rubber belt production for optimal cross-linking.
2-Mercaptobenzothiazole (MBT) Powder
2-Mercaptobenzothiazole (MBT) is a heterocyclic compound containing a benzothiazole ring system, primarily used as an accelerator in rubber vulcanization processes. It is a separate chemically defined compound.
Benzothiazole Disulfide Powder 98%
Technical grade 98% 2,2'-dithiobisbenzothiazole powder for large-scale rubber processing plants. It is a chemically defined benzothiazole structure with allowable impurities, classified as a heterocyclic compound.
Benzothiazole TBBS 95% Technical Grade
Technical grade N-tert-Butyl-2-benzothiazolesulfenamide (TBBS) at 95% purity, a chemically defined heterocyclic compound containing an unfused benzothiazole ring-system. It is used as a vulcanization accelerator in rubber formulations for footwear soles and other industrial rubber goods.
Captax MBTS Rubber Accelerator
Captax MBTS is the commercial grade 2,2'-dithiobisbenzothiazole used in tire and rubber manufacturing as a delayed-action vulcanization accelerator. It contains the specific benzothiazole ring-system required for this tariff item.
CBS Benzothiazole Sulfenamide Accelerator
CBS (CZ) is N-Cyclohexyl-2-benzothiazole sulfenamide, chemically related to named NOBS via benzothiazole structure. Provides excellent processing safety for automotive rubber components.
MBTS Dibenzothiazole Disulfide
MBTS, derived from 2-Mercaptobenzothiazole, contains two benzothiazole rings linked by a disulfide bond, qualifying under this tariff item. It is a slow-curing accelerator used in EPDM rubber formulations.
NOBS-60 Pre-Dispersed MBTS Accelerator
NOBS-60 is a 60% dispersion of 2,2'-dithiobisbenzothiazole on a polymer carrier for even distribution in rubber mixes. Despite the dispersion, the active ingredient's benzothiazole structure qualifies it under this tariff item, provided the carrier does not render it particularly suitable for specific use.
NOBS MBS Rubber Accelerator 95% Powder
MBS (MOR) is 2-(Morpholinothio)benzothiazole, a sulfenamide accelerator analogous to named NOBS. Provides balanced cure rate and scorch resistance for conveyor belts.
N-tert-Butyl-2-benzothiazolesulfenamide (TBBS)
N-tert-Butyl-2-benzothiazolesulfenamide (TBBS) is a sulfenamide accelerator with a benzothiazole ring-system, not further fused. It is a separate chemically defined organic compound used primarily in rubber vulcanization processes.
Runflex TBBS Vulcanization Accelerator
Runflex TBBS is N-tert-Butyl-2-benzothiazolesulfenamide meeting industrial specifications for rubber curing. It contains the characteristic benzothiazole ring-system and is classified as a heterocyclic compound not further fused.
Santocure TBBS Accelerator
Santocure TBBS is a branded form of N-tert-Butyl-2-benzothiazolesulfenamide, a sulfenamide accelerator with the defining benzothiazole ring-system. It is used in natural and synthetic rubber for optimal vulcanization.
TBBS 98% Rubber Accelerator Powder
High-purity (98%) N-tert-Butyl-2-benzothiazolesulfenamide powder formulated for delayed-action vulcanization in rubber compounds. Its benzothiazole ring-system qualifies it as a heterocyclic compound under this tariff item.
