Molecular structure：
Synoflex® TOP is a trialkyl phosphate with low volatility and high thermal stability. It is widely used as a cold-resistant plasticizer for PVC and synthetic rubbers, improving flexibility, processability, and mechanical properties such as heat resistance, weatherability, UV stability, anti-aging, flame retardancy, and antimicrobial functionality. TOP also serves as an effective solvent in coatings and printing inks, enhancing viscosity and flow characteristics. With good compatibility with various polymers, it is a versatile high-performance industrial additive.
