The DBD rubber processing agent, scientifically known as 2,2'-dithiobis(benzamide) (CAS Number: 135-57-9), is a highly efficient rubber additive that enhances the performance of various types of rubber formulations. This agent comes in a pale yellow powder form, characterized by its low toxicity and environmentally friendly attributes.
The chemical composition of DBD is represented by the formula C26H20N2O2S2, with a molecular weight of 456.58. It is soluble in many organic solvents such as benzene, ethanol, and acetone while remaining insoluble in water. These properties make DBD a versatile choice for various rubber processing applications.
DBD is primarily used in the formulation of natural rubber, synthetic rubber, or rubber alloys. It is typically added in emulsifying machines containing crude rubber, introduced promptly to mixers after depolymerization. The optimal working temperature for DBD is approximately 155°C ± 5°C, with a recommended dosage ranging from 0.1 to 0.5 parts.
This rubber processing agent offers excellent storage stability; however, it is essential to store it in a cool, dry, and well-ventilated area, protected from direct sunlight. DBD is available in various packaging options, predominantly comprising 25kg plastic woven bags, paper with plastic film bags, and Kraft paper bags, ensuring convenience for transportation and storage.
In conclusion, DBD serves as a remarkable rubber processing agent that significantly enhances the quality and efficiency of rubber production. Its favorable properties and versatile applications make it an essential additive in the rubber industry.
