High-Efficiency Anti-Yellowing Solution for Polyurethane Elastomers – OMNISTAB AY7690

2025.06.20

Compared to other elastomers and rubber materials, polyurethane elastomers offer advantages such as lightweight, wear resistance, oil resistance, aesthetic appeal, and comfort, along with ease of manufacturing and processing. They are widely used in automotive interiors, footwear elastomers, electronics, electrical appliances, and medical fields.

 

However, unmodified polyurethane materials undergo oxidation in their molecular chain structure during processing and subsequent use, leading to yellowing, cracking, and a decline in mechanical properties. Yellowing not only affects the appearance of polyurethane materials but also indicates a significant reduction in their functional performance.


OMNISTAB AY7690 is a highly effective anti-yellowing agent specifically designed for polyurethane materials. It significantly delays material aging, maintains stable product color, and enhances market competitiveness.

 

Advantages of OMNISTAB AY7690

>Outstanding Anti-Yellowing Performance: AY7690 effectively prevents yellowing in polyurethane materials during processing, storage, and application, particularly yellowing caused by nitrogen oxides (gas fume yellowing).


>Wide Applicability: AY7690 is widely used in the production of polyurethane profiles, elastomers, fibers, coatings, and other products. It can be applied before or during polymerization, delivering stable performance and excellent compatibility.


>High-Temperature Stability: Maintains superior performance even under high-temperature processing conditions.


>Synergistic Effects: When used in combination with UV absorbers and stabilizers, AY7690 exhibits a synergistic effect, significantly improving the material's long-term UV resistance and weather durability.
