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.
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
