One minute to understand rubber vulcanizing agent


Rubber vulcanizing agent is a substance that enables natural rubber and synthetic rubber to cross-link at high temperatures, thus improving rubber properties. Rubber vulcanizing agent has the following advantages:

1. Improvement of rubber strength

The vulcanizing agent can change the single bond between the rubber molecular chains into a double bond, forming a cross-linked structure. This cross-linking structure can improve the strength, hardness and abrasion resistance of rubber, and also increase the elasticity and tensile properties of rubber.

2. Improve heat resistance

The vulcanizing agent can make the rubber molecular chain form a three-dimensional network structure, so that the rubber has better heat resistance and aging resistance. Under the high temperature environment, the vulcanized rubber can maintain its original performance and will not soften or deform.

3. Improve chemical resistance

Vulcanized rubber has better chemical resistance, and can resist the corrosion of acids, alkalis, solvents and other chemicals. Therefore, vulcanized rubber is often used in the manufacture of chemical laboratories, chemical plants and other places in the pipeline and equipment.

4. Improve adhesion

The vulcanizing agent can make the rubber surface generate a vulcanized layer, so that the rubber has better adhesive properties. The vulcanized rubber can be better adhered to the surface of different materials such as metal, glass, plastic, etc. It is widely used in the manufacture of seals, pipes and other products.

5. Improve production efficiency

Vulcanizing agent can accelerate the rubber vulcanization reaction, shorten the vulcanization time and improve the production efficiency. At the same time, in the vulcanization process, the vulcanizing agent can also make the rubber surface smooth, improve the overall aesthetics of the product.

In summary, rubber vulcanizing agent plays an important role in the production of rubber products. It can improve the physical, chemical and mechanical properties of rubber and make rubber products more durable, beautiful and safe. At the same time, vulcanizing agent can also shorten the production cycle and improve production efficiency.

Rubber vulcanizing agent is an important raw material to transform rubber into hardened, enhanced abrasion resistance, elasticity and other properties. It has many unique characteristics.

First of all, rubber vulcanizing agent has a good promotion effect. By adding an appropriate amount of vulcanizing agent, it can accelerate the cross-linking effect between rubber molecules and promote the rubber to become a more compact structure. In this way, the rubber is more wear-resistant, corrosion-resistant and aging-resistant when in use.

Secondly, rubber vulcanizing agent is diversified. Different kinds of vulcanizing agents have different promotional effects, which can make the rubber show different properties under different conditions. For example, thioisobutyrate vulcanizing agents with better heat resistance are suitable for manufacturing vulcanized rubber with high temperature viscosity.

In addition, rubber vulcanizing agents can also affect the processing properties of rubber. In the presence of a vulcanizing agent, the rubber flows and mixes better, and the processing properties become better. This allows for the manufacture of rubber products with more complex shapes and higher precision.

In short, rubber vulcanizing agent has diverse characteristics and obvious advantages. In the production process of rubber products, choosing the right vulcanizing agent can better meet the requirements of specific applications and improve the performance and quality of rubber products.

Rubber vulcanizing agent is a chemical additive that promotes cross-linking of rubber molecules to form a stable and strong substance. It can be divided into two categories, inorganic vulcanizing agents and organic vulcanizing agents, depending on its nature.

The more commonly used inorganic vulcanizing agent is sulfur. Sulphur decomposes when heated, releasing free sulphur, which reacts with the double bonds in the rubber, thus promoting rubber vulcanization. Inorganic vulcanizing agents have less impact on rubber processing properties and are suitable for the preparation of articles such as vulcanized rubber.

Commonly used organic vulcanizing agents are thioisobutyrate, benzene sulfate, polysulfide and so on. The role of organic vulcanizing agents in vulcanized rubber is similar to that of inorganic vulcanizing agents, but can often provide a wider range of promotional effects. As a result, organic vulcanizers have a wider range of applications and can be used in a variety of different rubber product manufacturing processes.

In general, the choice of rubber vulcanizing agent needs to be based on the use and performance requirements of the rubber product. For example, if you need to make high heat performance items, you can choose thioisobutyrate type vulcanizing agent; if you need to process rubber products with good performance and simple process, you can choose benzene sulfate type vulcanizing agent and so on.

In general, there are many kinds of rubber vulcanizing agents and their scope of application, which need to be selected according to the actual situation in order to obtain better rubber products.

What are the advantages of rubber additive pre-dispersion?

Environmental protection. Avoid workshop dust pollution, protect workers' health.


Why is pre-dispersion of rubber additives the trend?

Rubber additives are chemicals that bring high added value to rubber products and can reduce costs. However, the traditional rubber additives not only produce a lot of dust and toxic and harmful gases when used,


Rubber vulcanizing agent is a substance that induces a vulcanizing reaction in rubber.

A rubber vulcanizing agent is a substance that induces a vulcanizing reaction in rubber. Vulcanization is the process by which rubber undergoes a chemical reaction to form a cross-linked structure, increasing elasticity and wear resistance. In industrial production, rubber vulcanizing agent is widely used in automobile tires, rubber hoses, flooring, cables and other fields.


Main characteristics of rubber vulcanization accelerators

Rubber vulcanizing agent manufacturers tell you that the activation temperature is low, the curing speed is fast, and the crosslinking degree is high. However, it is easy to burn, poor flatness, improper vulcanization operation, easy to cause insufficient sulfur or too much sulfur. It is suitable for fast vulcanizing thin products of butyl rubber and EPDM rubber, room temperature vulcanizing products, latex products and vulcanizing products.
