Description

n-Isopropylbenzothiazol-2-Sulphenamide is a high-purity sulfenamide derivative primarily used as a delayed-action accelerator in the rubber vulcanization process. Its core value lies in providing an optimal balance of processing safety and fast curing rates, which is critical for manufacturing high-performance rubber goods. This compound is essential for producers in the tire, automotive parts, and industrial rubber goods sectors seeking to enhance product durability and production efficiency.

Application

• Primary delayed-action accelerator for sulfur vulcanization of natural and synthetic rubbers.
• Manufacturing of tire treads, sidewalls, and other tire components requiring excellent physical properties and aging resistance.
• Production of automotive belts, hoses, seals, and gaskets where consistent cure characteristics are vital.
• Formulation of industrial rubber products such as conveyor belts, rollers, and vibration dampeners.
• Used in combination with other accelerators (like thiurams or dithiocarbamates) to create efficient curing systems with reduced risk of scorching.
• Enhances the reversion resistance of thick rubber articles during prolonged high-temperature curing.

Quality Control

Our n-Isopropylbenzothiazol-2-Sulphenamide is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes comprehensive analytical testing, including assay, melting point determination, and impurity profiling, to meet stringent industry specifications. Certificates of Analysis (COA) detailing all quality parameters are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Keep away from heat sources, open flames, and incompatible materials. Due to its light-sensitive nature, containers should be kept in the original packaging or opaque containers until use.
