Enhanced polarity and reactivity due to controlled maleic anhydride grafting, enabling strong interfacial adhesion with polar substrates.
Excellent thermal stability and low volatility, suitable for high-temperature processing up to 220 °C.
Low melt viscosity and superior dispersion characteristics in polymer melts and pigment masterbatches.
Improved compatibility with engineering resins such as PA6, PBT, and PET, facilitating uniform filler distribution.
Consistent batch-to-batch performance ensured by Mitsui Chemicals’ proprietary controlled-grafting technology.
Pigment dispersant in color masterbatches for polyolefins and engineering plastics.
Compatibilizer in polyolefin–polar polymer blends (e.g., PP/PA, PE/PET).
Processing aid in filled thermoplastics to reduce torque and improve extrusion efficiency.
Surface modifier for mineral-filled composites to enhance filler–matrix bonding.
Functional additive in wood–plastic composites (WPC) to improve wood fiber dispersion and moisture resistance.
