Dual Lubrication: Polar groups provide strong internal lubrication, while the long-chain alkane structure provides external lubrication;
High Dispersion and Coupling: Polar functional groups adsorb onto filler/pigment particles, preventing agglomeration, enhancing dispersion uniformity, and improving interfacial bonding strength;
Thermal Stability Synergy: Some acidic groups help absorb HCl generated during degradation, extending the thermal stability of PVC and reducing efflorescence and blooming.
