Antioxidant masterbatch

Antioxidant Masterbatch is a specialized additive in polymer industries that is produced to increase the thermal and chemical stability of polymers against destructive factors such as heat, oxygen and sunlight. This masterbatch, with a combination of antioxidant materials in a suitable carrier resin base, is used in the production processes of plastic parts, films and polymer fibers. At Behin Polymer, we produce various types of antioxidant masterbatch with the highest quality and specialized formulations.

What is antioxidant masterbatch?

Antioxidant masterbatch is a concentrated blend of antioxidant additives in the form of granules in a polymer matrix. The main function of this blend is to inhibit oxidation chain reactions that lead to the breakdown of polymer chains. Also, the use of this blend in the packaging, automotive, and various engineering components industries plays a vital role in enhancing the durability and shelf life of products.

Antioxidant masterbatch; an agent that protects polymers against degradation.

Polymers are subject to various types of degradation that can severely affect their properties. One of the most important of these is thermal degradation. This type of degradation occurs when a polymer is exposed to high temperatures, such as during manufacturing processes such as extrusion, injection molding, or even during the final application of the product in hot environments.

Some other types of polymer degradation include:

• Oxidative Degradation: Reaction between oxygen in the air and the polymer that causes the formation of free radicals and the breakage of polymer chains.
• UV Degradation: caused by the absorption of ultraviolet radiation by the polymer and the excitation of chemical bonds, which leads to structural degradation and appearance changes on the surface of the part.
• Mechanical Degradation: Due to mechanical stresses such as impact, tension, and continuous abrasion, polymer chains break and the strength of the part decreases.

Consequences of polymer degradation

Polymer degradation has several consequences on the performance and appearance of the product. The most important results are a decrease in mechanical properties such as a decrease in tensile strength, a decrease in impact resistance, and a decrease in flexibility. In addition, the appearance of the parts undergoes changes such as yellowing, dulling, and the formation of micro-surface cracks, which reduce the visual quality and marketability. Ultimately, these factors reduce the useful life of the final products.

How does antioxidant masterbatch prevent polymer degradation?

Antioxidant Masterbatch prevents the degradation of the polymer structure by inhibiting oxidation chain reactions and free radical decomposition. This masterbatch, by releasing active compounds at process temperature and environmental conditions, reacts with free radicals and does not allow new degradation chains to form. Also, the existing antioxidants, by absorbing high-energy radicals and converting them into stable compounds, stop the degradation process and ensure the stability of the physical and mechanical properties of the polymer during production and consumption.

Types of antioxidants based on mechanism

Antioxidants are divided into two categories based on their mechanism of action. Primary antioxidants, also known as radical scavengers, are responsible for directly neutralizing free radicals. These compounds are often phenolic or amine-based and prevent the initiation of oxidation chain reactions at process temperatures and product life. They have a preventive role and are mostly used in polyethylene, polypropylene and elastomers.

Secondary Antioxidants, also known as Peroxide Decomposers, prevent the degradation reaction from continuing by breaking down peroxides into stable, non-radical compounds. This group is activated at high temperatures and is commonly used in combination with primary antioxidants in antioxidant masterbatch formulations to enhance their protective efficacy. This synergistic performance maximizes the thermal and chemical stability of the polymer against environmental and process factors.

Antioxidant masterbatch components

Antioxidant masterbatch consists of several components. The most important of them are primary and secondary antioxidant compounds with optimized percentages according to the type of polymer and process conditions. On the other hand, the resin base (Carrier Resin) in which the antioxidants are distributed must be compatible with the polymer matrix. Also, in some formulas, optical stabilizers and auxiliary compounds such as processing aids are also added to the masterbatch to ensure the stability of the composition and uniform distribution of additives in the final product.

Benefits of using antioxidant masterbatch

The use of antioxidant masterbatches has significant advantages. First, it improves the thermal and oxidative stability of the polymer during the production process and the service life. This reduces waste, improves surface quality and increases the uniformity of the mechanical properties of the manufactured parts. On the other hand, adding this masterbatche to the production process is very easy and cost-effective and allows for accurate and uniform dosing.

Another benefit of antioxidant masterbatch is that it preserves the appearance of the product and prevents discoloration, yellowing, and cracking in various environmental conditions. This additive also significantly increases the lifespan of the product, especially in parts used outdoors and in high-temperature industrial environments.

Applications of antioxidant masterbatch

Antioxidant masterbatch is used in a wide range of industries. For example, this product, due to its stable performance, is used in the production of various types of PE, PP, EVA, PA and ABS based polymers. Some of the applications of this type of masterbatch are:

• Packaging films: to protect against heat and light to prevent yellowing and loss of properties
• Automotive parts: with the aim of increasing durability and resistance to engine heat and sunlight
• Polymer pipes and fittings: To prevent cracking and reduced life from oxygen and high temperatures.
• Tanks and containers: a factor in maintaining transparency and strength against industrial environments
• Greenhouse and agricultural components: to protect against UV damage and summer heat
• Electronic products: To prevent yellowing of the body polymer and loss of mechanical properties
