Used primarily as a high-performance plasticizer and additive in specialty polymers, this chemical enhances flexibility, thermal stability, and durability in rubber and resin formulations. It is especially effective in applications requiring resistance to heat and aging, such as in automotive seals, industrial hoses, and electrical insulation materials. Its unique cyclic imide structure contributes to improved adhesion and compatibility with polar polymers, making it suitable for advanced coating systems and impact modifiers in engineering plastics. Additionally, it finds use in wire and cable compounds where long-term performance under stress is critical.
