1. Introduction

Rubber Active Agents (RAs) are a class of rubber agents. They are produced by mixing rubber latex with sulfuric acid and vulcanizing the mixture at high temperatures. They have been widely used in various industries, including aerospace, automotive, construction, drilling fluids, and lubricants. They’re also used in the area of composite materials, especially for reinforcement of reinforced concrete structures.
One thing that makes them interesting is that some RAs can be used as cross-linking agents for other rubber materials. This means that they are good substitutes for cross-linking materials in other rubbers or be used as additives to improve the quality of others.

2. What are Rubber Active Agents?

Once a rubber compound is vulcanized, it has a relatively low strength, and the material becomes brittle. To improve this property, you can use rubber active agents as a bridging agent between the rubber compound and the vulcanizing agent (such as peroxide).
Rubber Active Agent is an agent that helps to improve the strength of rubber compounds. It can be used as a bridge between two compounds.
  • Rubber Active Agent improves the strength of rubber compounds
  • It can be used as a bridging agent between two compounds
  • It is more stable than a rubber vulcanizing agent
  • It has good compatibility with other materials, such as plastic and steel

3. The advantages of Rubber Active Agents

Rubber active agents are combined with peroxide vulcanization and can be used as a bridging agent to improve bridging density, improve tensile strength, reduce compression deformation and shorten vulcanization time.
Rubber active agents are molecules that have an active part and a reactive part. The reactive part is fixed to the rubber and the active part is located in an environment so that it is reactivated by other molecules such as vulcanizable material. So, this molecule is called a rubber active agent or rubber microbead. Rubber microbeads are used in various industries (electronic industry, textile industry, chemical industry) to increase the number of bonding sites between wetting agents and solvents.

4. How Rubber Active Agents work

Rubber Active Agents are synthetic rubber compounds that contain a blend of natural and synthetic rubber compounds. They are referred to by the number of compounds used in each molecule. For example PG, PG-10, HVC-10, and HVC-12.
The properties of rubber active agents can be broadly classified into physical properties such as mechanical strength, elastic modulus, tensile strength, elongation modulus, and rupture force.
Rubber Active Agents can be used in various applications such as construction materials for concrete reinforcement (or thermal insulation), plastic materials for impact-resistant components in automobiles and the aerospace industry, reinforcing materials for automotive fuel tanks, and airbags in cars interiors, etc.
In order to improve the bonding strength of rubber active agents, peroxide vulcanization is often used instead of curing oils with anionic surfactants (e.g., sodium lauryl sulfate). In order to improve the performance of these products, rubber active agents are usually mixed with resins or binders and applied directly on the surface of a substrate (such as a polymer). The purpose is to cover both sides of a product surface so that it is completely covered with a rubber active agent without cutting through it (i.e., it is effectively stuck on).

5. The benefits of using Rubber Active Agents

Rubber Active Agents can be used in a wide variety of applications, from easily interchangeable products to highly specialized ones. Its mechanical properties can be modified through the use of vulcanization cycles.
Rubber Active Agents are composed of a high-volatility organic solvent and an organic polymer (e.g., polyurethane) and are used as a bridging agent for the vulcanization of rubber compounds. They can also be used to reduce compression deformation (CDA), improve tensile strength, reduce compression deformation during vulcanization, shorten vulcanization time, and improve water stability. All these benefits are achieved with some form of peroxide treatment applied to the rubber compound before the cross-linking step with monomer (e.g., 2-butoxy ethoxy ethyl methacrylate).

6. The drawbacks of Rubber Active Agents

Rubber active agents are used to improve the stiffness of the rubber.
Rubber Active Agents are a new product that consists of a composition of double-base rubber, and a chemical crosslinking agent, and then vulcanization is performed by mixing these two components in water.
In the first stage, by adding peroxide as a catalyst, vulcanization can be performed at a high temperature. Then after reaching the desired temperature, this catalyst can be used as a crosslinking agent to improve the flexural rigidity and tensile strength of rubber. Removing the moisture from the vulcanizing process can shorten the vulcanization time for compound rubber.
Besides that, there are other benefits of Rubber Active Agents in comparison with conventional curing agents including:
  • higher chemical resistance
  • improved bond strength
  • shorter curing time
  • better appearance
  • reduced shrinkage during processing
  • reduced deformation during stress deformation test

7. Conclusion

Rubber Active Agents are a great way to improve the properties of rubber, but when it comes to performance, you have to improve both performance and cost. For example, if you are looking to improve the tensile strength, you can mix in with the rubber active agent a few percent of hardener. Of course, there is no need for this. If you want an increase in cost, you can always add more hardener to the rubber active agents and the ones that come out on top will be the ones with higher price tags.
We have some advantages over alternatives:
Rubber Activeagents are a combination of peroxide vulcanization and hardener, which brings benefits like improved tensile strength and reduced compression deformation during curing. This combination has been shown in research to boost both mechanical properties like tensile strength and compressive modulus, as well as mechanical properties like hardness.
It is important to note that each one of these properties will be different depending on your specific application needs. For example, there is no point in improving tensile strength if it doesn’t do anything useful for your product (e.g., if your product is just a clothes hanger). It’s important because it allows us to find combinations that give us real benefits without having to sacrifice too much other quality or functionality (and hence we can be sure our finished product will be superior in all those areas).
