Hindered phenolic antioxidant benchmark, solving the root cause of anti-aging problems-OMNISTAB® AN565

Rubber is an indispensable basic material in industrial systems, featuring unique high elasticity, wear resistance and sealing properties. It is widely used in daily life and high-end manufacturing fields: from sealing rings and gloves to car tires and shock-absorbing rubber pads, none of them can do without the support of rubber. The quality and lifespan of rubber products are directly related to the performance, safety and user experience of the final products. In industrial production, the thermal and oxidative aging of materials is a core problem affecting product quality and service life - rubber is prone to cracking, resin is easy to degrade, and finished products are prone to discoloration. This not only increases production costs but also may cause safety hazards. OMNISTAB ® AN565 is a high-molecular-weight multifunctional hindered phenolic antioxidant with excellent thermal oxidation resistance, making it an ideal solution for material anti-aging.

Omnistab ® AN565 has multiple advantages

● Low consumption and high efficiency, achieving long-term protection

With a hindered phenolic molecular structure, it has stronger antioxidant activity. Only a small amount of addition is needed to achieve long-lasting and comprehensive antioxidant protection. It also has the characteristic of low volatility, is not easily lost during high-temperature processing, and can continuously play a role. The advantage of high color fastness can effectively prevent materials from yellowing and discoloration, and can well ensure the consistency of product appearance.

● Dual-effect synergy, enhanced antioxidant capacity

Omnistab ® AN565 has dual functions as a primary and secondary antioxidant: As a primary antioxidant, its hindered phenolic groups can bind to peroxide radicals (ROO ·) and alkoxane radicals (RO ·) generated during the oxidation process, directly terminating the oxidation chain reaction and blocking material degradation from the source. As a co-antioxidant, its sulfide structure can efficiently decompose hydroperoxides (ROOH), preventing them from decomposing into new active free radicals and inhibiting the regeneration cycle of the oxidation chain. This not only achieves intramolecular synergistic protection but also can be used in combination with other antioxidants, significantly enhancing the antioxidant effect.

● It has good compatibility and meets environmental protection requirements

It has good compatibility with most materials, low toxicity, and causes little color pollution, meeting the environmental protection requirements of industrial production and having no negative impact on various materials.

Omnistab ® AN565 is suitable for the post-processing stabilization treatment of unsaturated rubber and has excellent protective effects on various elastomers. It can be widely applied to materials such as butadiene rubber (BR), isoprene rubber (IR), styrene-butadiene rubber (SBR), nitrile rubber (NBR), melt-polymerized styrene-butadiene rubber (SSBR), and styrene-butadiene-styrene block copolymer (SBS). Whether it is general rubber products or high-performance elastomer components, they can precisely match the protection requirements and avoid the performance degradation problem caused by thermal oxidation degradation from the source.
