CasAO Antioxidants
High-Performance Antioxidants for Longer-Lasting Polymers
Our high-performance antioxidants protect polymers against heat and oxygen, helping maintain performance, appearance, and reliability over extended service life. Designed for demanding conditions, they support durability in tyres, rubber goods, plastics, adhesives, and lubricants.
Thermal & Oxidative Stability
Formulated to shield polymers from thermal and oxidative degradation, our antioxidants help prevent embrittlement, cracking, and loss of properties under harsh processing and end-use conditions.
Extended Product Lifespan
By preserving mechanical, physical, and optical properties over time, these antioxidants support longer-lasting, higher-value products with reduced maintenance and replacement costs.
Versatile Applications
Effective across a wide range of systems—including tyres, technical rubber goods, thermoplastics, adhesives, sealants, and lubricants—our portfolio supports both new formulations and optimisation of existing products.
Reliable Supply
Backed by secure sourcing and a robust global distribution network, our antioxidants offer consistent quality, dependable availability, and support for regional and worldwide manufacturing operations.
