Vulcanising Agents, What Are These And What Are They Advantages?

Vulcanization is a well known process among the rubber industry. It is a chemical process that is used to turn the natural rubber and other polydiene elastomers into cross-linked polymers. Doing so will help to improve the characteristics of rubber and make it more durable to turn it into the materials that can be used in our daily lives. Vulcanization is not possible without its vulcanizing agents. So it is important to talk about vulcanizing agents as well. 



Vulcanising agents

Sulfur is the most common vulcanizing agent, but when talking about Vulcanizing agents, they can be easily divided into two different categories. Organic curing agent and inorganic vulcanizing agents.

Inorganic Vulcanizing Agent: Sulfur, sulfur monochloride, tellurium, selenium, etc.

Organic Curing Agent: Accelerators that contain sulfur such as TMTD, benzoyl peroxit, polysulfide polymers, etc. 

Advantages of Vulcanization:

Improves the tensile strength and extensibility.

Offer excellent resilience i.e. the rubber will return to the original shape, after the removal of the deforming load.

It will absorb less water.

Improves resistance to oxidation, wear and tear abrasion.

Better electrical insulator.

It is resistant to organic solvents, fats and oils.

Workable temperature range of -40.C to 100.C

What Is Sulfur Blooming?

Image
 Rubber is the main raw material in the manufacturing of tires. Industry uses both natural and synthetic rubber for the purpose. To maintain the quality of rubber sulfur content is one of the most important parameters.  Raw rubber is a hydrocarbon in nature and is a thermoplastic. In order to eliminate the undesirable property of malodorousness, treating rubber with sulfur, other accelerators, and antioxidants are necessary. Which in turn helps to prolong the life of rubber product tires in this case.  However, being crystalline organic sulfur is somewhat soluble in polymers (rubber). Mixing ordinary sulfur to the natural rubber will be of no use as it will dissolve during the hot mixing process. Later after cool-down, it will form the crystallized surface, causing the sulfur to bloom. This might not affect the function of the rubber product but it will mess up the appearance of the product.  To prevent this undesirable effect of sulfur blooming , insoluble sulfur is used in Rubber.

What Is Rubber Blooming And How To Prevent It?

Image
 The crystallization of compounding ingredients that are usually present on the surface of stock, cured or uncured, are always accompanied by the migration of the substance from the bulk to the surface, this phenomenon is known as Blooming. Any ingredient which is soluble in rubber can undergo blooming. These additives are soluble in rubber at high temperature but when cools down it decreases the solubility which leads to the migration to the surface. Blooming results in reducing the thickness of the stock, which is not ideal in the manufacturing of the tires and belts. How To Prevent Blooming In Rubber? Sulphur blooming is one of the major issues tackled by the rubber industry using the insoluble sulphur. To complete the process while avoiding sulphur blooming, the insoluble sulphur is mixed in the compound and the processing temperature is kept below the transition point of sulphur.  That’s why insoluble sulphur is one of the most important components in the rubber industry.

Insoluble Sulfur And Properties It Offer To Rubber Manufacturing

Image
 Rubber and rubber components are widely used in all parts of the world, in various forms. Most of the time we don’t even notice them, but they have a big impact in simplifying our daily lives. However it will be very difficult to form rubber into what we are using today without the help of insoluble sulfur . Known as the best vulcanizing agent among the rubber manufacturers, insoluble sulfur is what helps to prevent blooming in rubber.  As we can not use the natural rubber due to its lack of characteristics, that’s why treating it with other chemicals under vulcanization helps rubber manufacturers to produce synthetic rubber with better characteristics, more tensile strength and improved resistance to heat and oxidation. However, storing insoluble sulfur compounds can get tricky, as it is an unstable chemical that reverts into rhombic sulfur at room temperature. That’s why it is necessary to maintain the desired environment. Or use other better grade insoluble sulfur such as crystex H
