In the demanding world of polymer processing, especially at elevated temperatures, maintaining material integrity is a constant challenge. Polypropylene (PP) and other polymers are susceptible to thermal-oxidative degradation, leading to performance compromises and aesthetic issues like yellowing. Understanding and utilizing effective stabilizers, such as Antioxidant 136, is crucial for manufacturers aiming to produce high-quality, durable products. As a dedicated supplier of Antioxidant 136, we provide insights into its critical role.

The Threat of High-Temperature Processing

Processes like extrusion and injection molding often involve temperatures exceeding 200°C, sometimes even reaching 300°C or higher for specific polymers. Under these harsh conditions, polymer chains are prone to breaking and forming free radicals. When these radicals encounter oxygen, a cascade of degradation reactions begins, significantly impacting the material's properties. Key issues include:

  • Chain Scission: Leading to a reduction in molecular weight and loss of mechanical strength.
  • Cross-linking: Which can cause increased viscosity and brittleness.
  • Discoloration: Often appearing as yellowing or browning.

To combat this, effective antioxidant systems are indispensable. For those looking to buy robust solutions, our Antioxidant 136 manufacturer expertise is invaluable.

Antioxidant 136: A Superior Radical Scavenger

Antioxidant 136 is a highly effective carbon free radical scavenger. Unlike traditional antioxidants that might only target specific degradation pathways, Antioxidant 136 excels at directly capturing and neutralizing the highly reactive carbon and alkyl radicals that form during high-temperature processing, particularly in low-oxygen environments. This action is vital for halting the degradation chain reaction at its source.

Its effectiveness is further amplified when used in synergistic combinations. When paired with secondary antioxidants like phosphites, which decompose hydroperoxides, or with primary phenolic antioxidants, Antioxidant 136 significantly boosts the overall stabilization package. This synergy means:

  • Enhanced Processing Stability: Polymers remain stable, retaining their melt flow index and structural integrity.
  • Improved Color Retention: Minimizes yellowing, ensuring aesthetic appeal.
  • Long-Term Thermal Stability: Protects the polymer during its service life.

Many manufacturers seek a reliable supplier in China for such advanced additives, and our commitment to quality ensures you get the best.
