N-Cyclohexylthiophthalimide (NTP) Rubber Accelerator
N-Cyclohexylthiophthalimide is an aromatic organo-sulfur compound used primarily as a rubber accelerator and vulcanization retarder in tire and rubber manufacturing. It features a phthalimide ring with a cyclohexyl group and sulfur linkage, fitting Chapter 29 note for organo-sulfur compounds where sulfur is directly linked to carbon. Classified under 2930.90.24.00 as a specific aromatic thiophthalimide derivative.
High-Purity N-Cyclohexylthiophthalimide for Synthetic Rubber
This high-purity grade of N-Cyclohexylthiophthalimide serves as a nitrosamine inhibitor and retarder in synthetic rubber compounding, particularly for automotive tires. As an aromatic organo-sulfur compound with sulfur directly bonded to carbon in the thiophthalimide structure, it complies with Chapter 29 definitions excluding sulfonated derivatives. Specific subheading 2930.90.24.00 covers this exact chemical entity.
Industrial Grade N-Cyclohexylthiophthalimide Vulcanization Retarder
Industrial grade N-Cyclohexylthiophthalimide acts as a precise vulcanization retarder in natural rubber processing, controlling cross-linking for enhanced tire durability. Its aromatic structure with organo-sulfur functionality—sulfur directly linked to carbon—qualifies under heading 2930 per chapter notes, specifically named in subheading 2930.90.24.00.
NTP N-Cyclohexylthiophthalimide for Tire Manufacturing
NTP, or N-Cyclohexylthiophthalimide, is a specialty organo-sulfur accelerator used in tire manufacturing to prevent premature vulcanization and reduce nitrosamine formation. This aromatic compound matches 2930.90.24.00 as it contains sulfur directly linked to carbon atoms, per Chapter 29 notes excluding sulfonated types.
Phthalimide Derivative N-Cyclohexylthiophthalimide Chemical Intermediate
This phthalimide derivative, N-Cyclohexylthiophthalimide, serves as a chemical intermediate in organo-sulfur synthesis for rubber chemicals. Classified in 2930.90.24.00 due to its aromatic organo-sulfur nature with direct carbon-sulfur bonds, aligning with Chapter 29 provisions for separate chemically defined compounds.
