TINTOLL Antioxidant Blends are composed of hindered phenolic primary antioxidants and phosphite secondary antioxidants, which work synergistically to provide excellent processing and in-use stability for polyolefins and other polymers.
TINTOLL Antioxidant Blends are easy to use and the mixing ratio can be adjusted to meet specific requirements.
For more than 30 years, TINTOLL has been committed to providing innovative high-performance light stabilizers and antioxidant solutions to meet the growing and changing technical needs of the global plastics market.
TINTOLL's various antioxidants play an important role in inhibiting and delaying the oxidation and degradation of polymeric materials. TINTOLL is available in a variety of physical forms as well as standard and custom blends. The choice of antioxidant depends on factors such as compatibility, color and thermal stability, volatility and stabilizer efficiency.
Synergistic Protection: Hindered phenols are primary antioxidants that excel at inhibiting the initial stages of oxidation. They scavenge free radicals that can initiate polymer degradation. However, they are less effective at preventing later stages of oxidation. Phosphites, on the other hand, are secondary antioxidants that effectively inhibit the propagation of oxidation. When combined, these two types of antioxidant additives for polymers work together to provide comprehensive protection against oxidation, offering a greater level of stability.
Extended Longevity: By combining hindered phenols with phosphites, the polymer's protection against oxidation is not limited to one specific stage. This comprehensive approach extends the lifespan of the polymer, ensuring that it maintains its properties and performance over an extended period.
Improved Processing Stability: HPAO / Phosphite blends not only protect polymers from oxidation but also enhance their processing stability. This means that the polymer can be processed more efficiently and with fewer issues like melt fracture or color change during manufacturing.
Versatility: The blending ratio of HPAO and phosphite can be adjusted to meet specific requirements for different types of polymers and applications. This adaptability makes it a versatile solution for various industries.
