POLYBOND™ 3349 is a coupling agent and compatibilizer for linear low-density polyethylene and polyamide blends. It is excellent for use in composites with high levels of glass or mineral fillers.
POLYBOND™ 3349 is a coupling agent for glass-filled polyethylene composites with high mineral filler levels. It enhances hydrolytic stability and strength when used to compatibilize polyethylene–polyamide blends. It also functions as a processing aid for halogen-free flame retardant wire and cable compounds by providing improved dispersion and mechanical properties.
Appearance: Off-white pellet
Melt flow rate (@ 190°C): 8.0 g/10 minute Maleic anhydride content: 1.0%–1.4%
Density (@ 23°C): 0.93 g/cm³
Bulk density: 0.6 g/cm³
Melting point: 123°C
Primary Chemistry: Maleic anhydride–modified linear low-density polyethylene
Improves dispersion of halogen-free flame retardants in wire and cable compounds
High maleic anhydride content gives sufficient functionality for use with high mineral-filler loading levels
Low performance of traditional compatibilizers in LDPE products or polyamide blends
Insufficient impact strength or brittleness of glass-filled polyethylene composites Dispersion issues with the use of halogen-free flame retardants in polyolefins and polyethylene alloys
Halogen-free flame retardant compounds for wire and cable
Linear low-density polyethylene (LLDPE) and polyamide blends
LLDPE composites with high mineral- or glass-filler loading
