Every polymer material that is used to produce a product is subject to oxidation from the beginning of the process of being placed in the production line to the end of the forming stage and production of the final product. If oxidation reactions occur in polymer raw materials, their physical properties and molecular structure are seriously changed. These changes make the expected use of the final product practically impossible and the life of the manufactured product is short. The solution to prevent oxidation reactions in the production process is to buy antioxidant powder. Stay with us to provide you with more information about this add-on.
Buying antioxidant powder is the best way to prevent the oxidation of raw materials
In general, polymeric materials are sensitive to oxygen. Of course, the level of sensitivity of these materials is different and some of them, including polystyrenes, have relatively good resistance to oxidation, but in contrast to another group of polymer materials, including unsaturated elastomers, they are highly vulnerable to oxidation. In any case, measures should be taken to prevent this from happening. So far, four methods have been identified to prevent the oxidation of polymer materials, which are:
- Creating fundamental reforms in the structure of polymer materials
- Creating a coating on the surfaces of materials that are more exposed to oxygen.
- Increasing the physical stability of polymeric materials by orienting them
- Buying antioxidants and adding them to polymer materials in the production process
Among the above four methods, the fourth solution is currently the most used. The reason for this is the affordable price of antioxidant powder. In fact, the cost of using the fourth method is lower compared to the other three methods, and at the same time, it has good efficiency.
How does antioxidant powder prevent polymer materials from oxidizing?
When in the production process, polymer materials are exposed to factors such as light, free radicals, heat, mechanical stress and catalyst residues, oxidation reaction occurs in them. The most important factors among the mentioned factors are free radicals, which very quickly cause the oxidation of polymer materials and change their structure.
Adding antioxidants to polymer materials in the production process prevents this problem from occurring; In this way, antioxidants react with free radicals much faster than polymeric materials and thus prevent the oxidation of polymeric materials.
Properties of antioxidants
Properties of antioxidants For all the antioxidants that are currently in the market, single properties cannot be listed. But there are a set of physical properties that are common to all antioxidants. These properties include:
- It is common to buy antioxidants in powder form. This is because they should be well distributed on the surface of the base polymer material and also melt easily when heated.
- In terms of color, they should not cause the slightest change in the base polymer.
- They should not be volatile to be able to protect polymer materials well.
- Non-toxicity is one of the very important factors that should be considered when buying antioxidants.
The price of antioxidant powder
Briefly, you got acquainted with the uses and characteristics of antioxidants in the production of plastic products. The price of antioxidant is lower compared to other conventional methods to prevent oxidation of polymeric materials. For this reason, the preference of many manufacturers is to use this additive to produce their products. For more information about the uses and price of antioxidant powder, you can call 02179615000.
