Overview

Grafted polymers are specialty polymers chemically modified with functional groups to improve compatibility, adhesion, and impact properties in composite and blend systems. They act as impact modifiers, compatibilizers, and coupling agents, bridging otherwise incompatible materials to deliver superior performance.

What Are Grafted Polymers?

These are polymers (such as polyethylene, polypropylene, EVA, or elastomers) grafted with reactive functional groups like maleic anhydride (MAH), acrylic acid, or glycidyl methacrylate (GMA).

This Grafting enables them to form chemical or strong physical interactions with fillers, reinforcements, or other polymers, leading to significantly improved interfacial bonding.

Key Applications

โœ… Impact Modification

  • Enhance toughness and impact resistance of engineering plastics like PA6, PA66, PBT, and ABS.
  • Used in automotive bumpers, housings, and appliances.

โœ… Compatibilization

  • Improve the adhesion and dispersion of fillers (glass fiber, talc, nanoclay) in polyolefins or polyamides.
  • Enable blending of immiscible polymers such as PP/PA, PP/PS, PE/PET.

โœ… Coupling Agent for Composites

  • Promote strong interfacial bonding between polymers and inorganic fillers or natural fibers, leading to higher mechanical strength.

โœ… Adhesion Promotion

  • Improve adhesion in multilayer films, coatings, and extrusion lamination.
