Guide to Purchasing Antioxidant Masterbatch

The world of polymers and masterbatches is endless, as we have explained in this article and many others. If you think that you have created a resistive and sturdy product using polyethylene or PVC, I must say you are greatly mistaken!

There is a challenge that manufacturers often overlook, which is the oxidation of plastic over time. Oxidation is a process where the molecules and the structure of the product combine with oxygen atoms, gradually leading to the degradation and wear of the physical structure of plastic materials (if iron can oxidize and rust, anything else can!) Overall, oxidation is a significant challenge, and interestingly, this issue occurs even during production, as polymer materials are exposed to very high temperatures, which can lead to degradation. The role of antioxidant masterbatch is to maintain the physical resistance of the polymer product, whether at high temperatures or in other various conditions that we will discuss later.

Main Types of Antioxidant Masterbatch

Now that you are more familiar with this material, we can assist you in selecting the appropriate product. Below are important points to consider when choosing and ordering an antioxidant masterbatch:

Primary Antioxidant: This type of masterbatch directly prevents the oxidation of the plastic product in the initial stage and protects the physical integrity of the plastic product.

Secondary Antioxidant: This masterbatch serves as a complementary addition to the primary one, in which the primary antioxidant prevents oxidation while the secondary antioxidant stops its progression, acting like a barrier.

Combination: The presence of both previous types together undeniably increases resistance; hence, there is a combined antioxidant masterbatch to control the entire antioxidation process.

Applications and Features 

In addition to providing resistance to oxygen, antioxidant masterbatch can also be resistant to heat. This masterbatch is compatible with most polymers and is resistant to chemical reactions as well. It is worth mentioning that this material significantly contributes to extending the lifespan of the product.

It is definitely natural that with such important and vital properties, this material has applications in various industries. Some of these industries include the following:

Packaging Industry: For example, materials such as nylon and garbage bags are among the products that utilize this masterbatch. In situations where goods may be exposed to poor weather conditions and humidity for a significant period, antioxidant masterbatch is a suitable option.

Pipes and Fittings: Pipes and items like this are usually oxidized and destroyed over a long period of time due to the wear and tear of the product itself and most importantly due to the weather conditions of the environment and will cause damage in the future. That is why we use this material to prevent this event.

Automotive Industry: No one would want their car body to rot and crumble over time, especially if they live in a humid and damp environment!

And as usual, there are many other industries where this masterbatch can be used, we tried to name the most important ones here.
