1. What are Rubber Active Agents?
Rubber active agents (RAA) are designed to improve the properties of rubber products. In this paper, we review the literature on RAA. We discuss various aspects of the design, selection and performance evaluation of RAA in rubber engineering. The benefits and drawbacks of various types of RAA are discussed and evaluated in terms of their primary roles in improving tensile strength, compressive strength, fatigue resistance and vulcanization time.
2. Applications of Rubber Active Agents
Rubber Active Agents (RAs) are a group of compounds that have properties that can turn into rubbery materials when exposed to heat and humidity.
They are used in a wide variety of industrial fields, including the production and storage of various industrial fluids, paints, adhesives and so on.
The most commonly produced RAs are n-alkylbenzene derivatives, which can be found in the form of the esters or ethers. They have very low melting points, but due to their large viscosity, very high temperature stability and good dimensional stability; they can also be used as rubber solvents.
3. Tensile Strength
Here is a great article from the Rubber Science Society. While this material is not made available to the public, it is very good, and filled with a lot of good information.
4. Compression Deformation
Rubber active agents are a key part of the bio-mimicking rubber process. They enhance the properties of natural rubber (which is made from animal waste) as well as synthetic rubbers such as polybutadiene, polyisoprene and polyisobutylene. They also enable other materials to be used in the process without losing the desired properties.
Rubber active agents are not just a pretty face, however: they can act as carriers for the rubber reactants, making them more resistant to heat and chemical changes. The process is very efficient and gives good yields of high-quality rubber due to large amounts of material being produced in a short time. Rubber active agents are also environmentally friendly; they do not require huge amounts of energy or plastic waste production, hence minimizing CO2 levels in the atmosphere etc.
In this post, we will look at some aspects of rubber active agents: what they are and how they can contribute to improved performance in high temperature applications. Some important things that you should know about them:
- The first thing to understand is that rubber active agents have some very special physical properties; they behave differently from other chemicals used in the process (such as solvents or lubricants). This makes them ideal for high temperature applications, being able to withstand extreme temperatures without affecting their function (and this is one reason why they have been used for decades for composites). This makes them very suitable for use in composite materials such as composites and thermoplastics where high mechanical strength is needed but low thermal conductivity is necessary due to environmental reasons (for example, water vapour condensation on windows and doors).
- Another important property that makes it suitable for use at high temperatures is that it does not form any phase bonding with the polymer matrix (this is different from catalysts which form phase bonding with polymer matrices — see our post on catalysts). This means that it can be pumped into areas where it would otherwise cause problems with phase separation (installing door handles, etc.).
- The third property that makes it suitable for use at high temperatures are its physical properties: its low melting point allows it to bond directly onto surfaces rather than forming hard “cups” which lead to poor adhesion. These properties mean that rubber active agents tend not only to bond more quickly than other chemicals but also have more effective sealing forces than other chemicals when applied onto surfaces.
