Propylene-maleic anhydride (PMA) grafted polymer wax offering excellent polarity and reactivity for enhanced interfacial adhesion.
Low molecular weight with narrow distribution, enabling uniform dispersion and improved processability in thermoplastic and thermoset systems.
High maleic anhydride grafting level provides superior compatibility with polar substrates such as glass fibers, mineral fillers, and engineering resins.
Thermally stable up to 220 °C, supporting high-temperature compounding and extrusion without significant degradation.
Non-toxic, non-halogenated formulation compliant with major global regulatory frameworks for industrial polymers.
Compatibilizer in polyolefin-based composites containing glass fiber or talc.
Dispersing aid for pigments and functional additives in masterbatch production.
Adhesion promoter in automotive interior trim and under-hood components requiring thermal resilience.
Surface modifier for improving printability and coating adhesion on polypropylene films and molded parts.
Processing aid in wood-plastic composites (WPC) to reduce melt viscosity and enhance filler wetting.
