Product Definition

Maleic anhydride graft polymers are produced by grafting maleic anhydride onto a base polymer chain—commonly polyethylene, polypropylene, or polystyrene—under controlled temperature conditions. The most prevalent method is the melting process, which ensures uniform distribution of the maleic anhydride moieties. The resulting material combines the polar anhydride groups with the non‑polar backbone, granting it excellent compatibility with a range of polymers. This dual character makes it an effective coupling agent for PA, PP, and PE blends, as well as a toughening and adhesive enhancer in wire‑and‑cable masterbatches, TPE encapsulations, and hot‑melt adhesives.
