Products classified under HTS 3812.10.50.00
CBS Rubber Accelerator (N-Cyclohexyl-2-benzothiazole sulfenamide)
CBS is a delayed-action rubber accelerator used primarily in tire manufacturing and other rubber products to control vulcanization speed. It falls under HTS 3812.10.5050 as a prepared rubber accelerator not elsewhere specified, containing sulfenamide compounds for optimal processing properties. This product ensures uniform curing and improved mechanical properties in natural and synthetic rubber.
MBTS Rubber Accelerator (Dibenzothiazyl disulfide)
MBTS serves as a primary or secondary accelerator in rubber compounding, particularly for EPDM and butyl rubber applications. Classified under HTS 3812.10.5050 as a prepared rubber accelerator, it provides scorch safety and functions well in neutral or alkaline systems. Commonly used in automotive seals, hoses, and belting.
TMTD Rubber Accelerator (Tetramethylthiuram disulfide)
TMTD is a fast-acting ultra-accelerator used in latex and dry rubber systems, often combined with other accelerators. It qualifies under HTS 3812.10.5050 as a prepared rubber accelerator, providing excellent processing safety in thin-walled articles like surgical gloves and balloons. Effective across wide temperature ranges.
ZDBC Rubber Accelerator (Zinc dibenzyldithiocarbamate)
ZDBC functions as a primary accelerator for latex systems and secondary activator in dry rubber compounding. Under HTS 3812.10.5050 as other prepared rubber accelerators, it's prized for low toxicity and odor in food-contact applications like baby bottle nipples. Provides rapid vulcanization at low temperatures.
DPG Rubber Accelerator (Diphenyl guanidine)
DPG acts as a secondary accelerator and activator enhancing thiazole accelerators in tire treads and mechanical goods. Classified HTS 3812.10.5050 as prepared rubber accelerator, it offers excellent storage stability and high-temperature performance. Non-staining and non-discoloring properties suit light-colored products.
ETU Rubber Accelerator (Ethylene thiourea)
ETU provides fast vulcanization for neoprene (CR) and chloroprene rubbers used in cables and weatherstripping. HTS 3812.10.5050 covers this prepared accelerator noted for excellent aging resistance in dynamic applications. Often used where high resilience is required.
NOBS Rubber Accelerator (N-Oxydiethylene benzothiazole-2-sulfenamide)
NOBS offers delayed action with rapid vulcanization ideal for thick rubber articles like truck tires. Under HTS 3812.10.5050 as other rubber accelerators, it provides processing safety and excellent physical properties. Sulfenamide chemistry ensures optimum cross-linking density.
TBBS Rubber Accelerator (N-tert-Butyl-2-benzothiazolesulfenamide)
TBBS is the industry standard accelerator for passenger car tires due to balanced scorch and cure rate. HTS 3812.10.5050 classification applies to this prepared sulfenamide accelerator providing superior treadwear resistance. Widely used in NR/SBR tire compounds.
ZMBT Rubber Accelerator (Zinc 2-mercaptobenzothiazole)
ZMBT serves as retarder, activator, and secondary accelerator across multiple rubber polymers. Classified HTS 3812.10.5050 as prepared rubber accelerator, it enhances adhesion in steel cord-rubber composites for tires. Offers excellent storage stability.
