POLYBOND™ 3029 provides improved tensile, flexural, and impact strength, as well as lower water absorption compared to general purpose coupling agents. It is ideal in wood and natural fiber-filled polyethylene composites.
Appearance: Off-white pellets
Melt Flow Rate (@190 °C): 4.0 g/10 minutes
Maleic Anhydride Content: 1.5-1.7%
Density (@ 23°C): 0.95 g/cm³
Bulk Density: 0.60 g/cm³
Melting Point: 130 °C
Primary Chemistry: Maleic Anhydride Modified High Density Polyethylene
High functionality reduces water uptake and improves strength in PE wood composites
Enhances hydrolytic stability in polyethylene - polyamide blends
Improves strength and impact properties in composites with high-loading rates of glass or mineral fillers
Improves dispersion and of halogen-free flame retardants in wire and cable compounds
Some food-contact approvals
Low performance of traditional compatibilizers in HDPE products and formulations
Insufficient impact strength and brittleness of wood fiber composites
High water absorption in polyolefins and polyethylene alloys
Performance and compatibility issues in wood and natural fibers composites
Ideal for use as a coupling agent in PE wood composites; dispersion aid in wire and cable compounds utilizing halogen-free flame retardants; improves strength in PE composites with high mineral or glass filler loading rates
