Description

Diisooctyl Sebacate is a high-performance, low-volatility diester plasticizer derived from sebacic acid and isooctyl alcohol. This compound is valued for its excellent compatibility with a wide range of polymers, providing superior low-temperature flexibility and resistance to extraction. It is a critical material for formulators seeking durable, high-quality plasticized products with enhanced performance characteristics. Key industries that rely on this plasticizer include specialty polymers, advanced lubricants, and high-performance coatings.

Application

• Primary plasticizer for polyvinyl chloride (PVC), polyurethane (PU), and other specialty polymers requiring excellent low-temperature flexibility.
• Functional fluid and base stock for high-performance synthetic lubricants and compressor oils.
• Key ingredient in high-quality, flexible sealants, adhesives, and caulking compounds.
• Plasticizer for nitrocellulose and other specialty coating formulations to improve film flexibility and durability.
• Additive in elastomer and rubber compounding to enhance processability and cold-weather performance.
• Component in specialty greases and metalworking fluids where thermal stability and low volatility are required.
