Features Of DuPont Fusabond N416 Toughener

  1. Maleic anhydride-grafted ethylene–propylene copolymer for enhanced interfacial adhesion between non-polar polyolefins and polar substrates.

  2. Enables improved impact resistance and ductility in filled or reinforced polypropylene (PP) and polyethylene (PE) compounds.

  3. Offers excellent melt processability and thermal stability during extrusion, injection molding, and compounding.

  4. Provides superior compatibility with both homopolymer and copolymer PP, as well as LDPE, LLDPE, and HDPE matrices.

  5. Supports low-migration performance in applications requiring regulatory compliance for indirect food contact (FDA 21 CFR §177.1520).

Typical Applications Of DuPont Fusabond N416 Toughener

  1. Automotive interior trim components requiring high impact strength and scratch resistance.

  2. Household appliance housings and structural parts where dimensional stability and toughness are critical.

  3. Industrial packaging containers for chemical resistance and drop-impact performance.

  4. Medical device trays and reusable equipment housings demanding consistent mechanical properties and sterilization compatibility.

  5. Multi-layer coextruded films and laminates requiring strong interlayer bonding between PE/PP and EVOH or PA layers.
