DuPont™ Fusabond® grafted polyolefin helps compounders toughen nylon and strengthen highly filled polyolefins

Fusabond® grafted polyolefin resins improve toughness and other end-use performance properties in polymer systems such as nylon resins (reinforced or non-reinforced), flame-retarded polyolefins, and wood-polymer composites.

 

Often used in nylon (polyamide, PA) impact modification systems, DuPont™ Fusabond® grafted polyolefin can help achieve super-tough performance and increase low-temperature impact resistance, where needed.  Intermediate toughening levels can be achieved at reduced cost (lower loadings).

Using Fusabond® can also improve flow for higher productivity or enhanced surface gloss in applications such as sporting goods.
 

These grafted polyolefin resins are functionalized, typically by maleic-anhydrate (MAH) grafting.

Typical benefits include:

  • Increased compatibility with polyamide for better dispersion and improved  impact performance.
  • Improved internal adhesion of glass fibers, mineral fillers, and flame retardants, etc. to the polymer matrix, resulting in a more uniformly distributed, more defect-free compound that helps end-users more reliably meet production and testing requirements.

In highly engineered compounds such as non-halogen flame-retarded (NHFR) wire and cable insulation, or higher-performance wood alternatives, using a DuPont™ Fusabond® grafted polyolefin resin can help build cost-effective performance in critical target areas such as impact toughness, stiffness/flexibility and moisture resistance.
