Description

Rubber Antiager Ky405, Min96% CAS NO 10881-67-1 is a high-performance phenolic antioxidant specifically engineered to protect rubber polymers from oxidative degradation and thermal aging. This compound is critical for extending the service life and maintaining the mechanical properties of elastomeric materials under demanding conditions. It is an essential additive for manufacturers in the tire, automotive parts, and industrial rubber goods sectors who require reliable long-term stability for their products.

Application

• Primary antioxidant in the production of tires, including treads, sidewalls, and inner liners.
• Stabilizer for automotive rubber components such as hoses, belts, seals, and gaskets.
• Protective agent in industrial rubber goods including conveyor belts, rollers, and vibration dampers.
• Additive for synthetic rubbers like SBR (Styrene-Butadiene Rubber), BR (Polybutadiene), and NBR (Nitrile Rubber) to prevent chain scission and crosslinking.
• Used in the compounding of rubber for footwear, sporting goods, and cable insulation.
• Enhances the aging resistance of rubber-modified plastics and thermoplastic elastomers (TPEs).

Quality Control

Our Rubber Antiager Ky405 is manufactured under a stringent quality management system to ensure batch-to-batch consistency and high purity. The product undergoes comprehensive analytical testing, including assay, melting point determination, and impurity profiling, to meet the specifications required by the rubber industry. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its nature of being easily oxidized, it is recommended to store under an inert atmosphere for long-term preservation and to minimize contact with air after opening the original packaging.
