Highly functionalized polypropylene-based maleic anhydride (PP-g-MA) copolymer with controlled molecular weight distribution.
Fine-grain powder form ensures excellent flowability and uniform dispersion in polymer blends and composites.
Superior compatibility and adhesion promotion between non-polar polyolefins (e.g., PP, PE) and polar fillers or reinforcements (e.g., wood flour, glass fiber, minerals).
Low volatility and minimal odor—suitable for demanding applications including automotive interior components and food-contact-compliant compounds (when formulated accordingly).
Consistent reactivity and grafting efficiency, enabling reliable performance in reactive extrusion and masterbatch production.
Wood–plastic composites (WPC) and natural fiber-reinforced polypropylene (NFRP) profiles for decking and cladding.
Automotive interior trim parts requiring enhanced filler-matrix bonding and dimensional stability.
Recycled polyolefin upgrading—improving mechanical properties and interfacial strength in post-consumer PP/PE blends.
Engineering thermoplastic compounds with mineral fillers (e.g., talc, calcium carbonate) for injection-molded structural parts.
Functional masterbatches for adhesion promotion in multi-layer coextruded films and laminates.
