Overview
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.
Specifications
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
Features & Benefits
- 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
Problems Solved
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
Applications
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
