Antioxidant Masterbatch: Protection Against Thermal & Oxidative Degradation
In plastic manufacturing, high processing temperatures, prolonged storage, and environmental exposure can cause polymer degradation—leading to discoloration, brittleness, and loss of mechanical strength. Antioxidant Masterbatch provides an effective shield against such damage by stabilizing polymers during both processing and end use.
It ensures that plastic products retain their color, strength, and appearance, even in demanding applications.
What is Antioxidant Masterbatch?
Antioxidant Masterbatch is a concentrated additive blend containing primary and secondary antioxidants dispersed in a compatible polymer carrier like PE, PP, or universal resin. These additives:
- Neutralize free radicals formed during high-temperature processing,
- Prevent oxidative degradation over time, and
- Extend the life span of plastic products.
This masterbatch is especially essential for polymers prone to heat aging, such as polyolefins (PE, PP), EVA, PS, ABS, and PET.
Technical Overview
Property | Specification |
Carrier Resin | PE, PP, EVA, or universal |
Active Ingredients | Primary & Secondary Antioxidants |
Typical Dosage | 0.5% – 2.0% |
Processing Compatibility | Up to 300°C |
Appearance | White / translucent / light yellow |
Compatibility | PE, PP, ABS, PS, PET, EVA, etc. |
Shelf Life | 12–24 months in sealed condition |
How It Works
Antioxidant Masterbatch contains two types of stabilizers:
- Primary Antioxidants (Radical Scavengers):
Interrupt oxidation chain reactions by neutralizing free radicals. - Secondary Antioxidants (Peroxide Decomposers):
Break down hydroperoxides into non-reactive compounds.
This synergistic effect ensures protection during both processing (short-term heat exposure) and product lifespan (long-term oxidation).
Conclusion
Antioxidant Masterbatch is not just an additive—it’s a performance safeguard. It ensures that your plastic products withstand heat, processing stress, and oxidative aging without losing strength or appeal. Whether you’re working with virgin resin or recycled compounds, this masterbatch is a vital component in delivering durable, reliable, and high-quality polymer products.

Frequently Asked Questions
Our FAQ section provides clear answers to common questions about white masterbatches, from product features to application details. We aim to help you understand how our solutions can improve your plastic products. If you have further inquiries, our team is always ready to assist you.
Why is antioxidant masterbatch important in plastics?
It prevents degradation caused by heat, oxygen, and light, preserving product quality.
Can I use it with recycled plastic?
Yes—it’s highly recommended for improving the stability of recycled resins.
What polymers are compatible?
Suitable for PE, PP, ABS, PS, EVA, PET, and more.
Will it affect color or transparency?
No—it’s typically neutral and designed to maintain visual clarity and color.
Is it safe for food-contact applications?
Food-grade variants are available upon request.
Does it interfere with other additives?
No—it is compatible with most colorants, UV, anti-static, and processing aids.
How is it different from UV stabilizer masterbatch?
UV stabilizers protect against sunlight, while antioxidants protect against heat and oxygen.
Is it needed in all plastic processes?
Especially crucial in high-temperature or long-term applications.
Does it prevent yellowing in clear films?
Yes—it helps maintain clarity and prevents yellow discoloration.
What is the typical dosage?
Usually between 0.5% and 2% depending on the application.
