Description

Di-n-Nonyladipate is a high-purity diester plasticizer synthesized from adipic acid and n-nonanol. This compound is valued for its excellent low-temperature flexibility and low volatility, making it a superior alternative to general-purpose phthalates in demanding polymer formulations. It is a critical raw material for manufacturers in the polymer, lubricant, and specialty chemical industries seeking enhanced performance and regulatory compliance.

Application

• Primary plasticizer for polyvinyl chloride (PVC), imparting excellent low-temperature flexibility and durability.
• Key component in high-performance synthetic lubricants and functional fluids.
• Plasticizer for nitrile rubber (NBR) and other specialty elastomers.
• Intermediate in the synthesis of specialty surfactants and emulsifiers.
• Additive in adhesives and sealants to improve flexibility and adhesion.
• Processing aid and internal lubricant in various polymer compounding operations.
• Functional fluid base for high-temperature and low-volatility applications.
