Features & Benefits
- Food contact approvals
- Great for glass-filled, mineral-filled, or cellulose-fiber-filled polypropylene
- Reduces water uptake
- Increases flexural and impact strength
- Compatibilizes polar and nonpolar materials
- Enhances hydrolytic stability in polypropylene–polyamide blends
- Acts as a coupling agent, process aid, and dispersion aid in halogen-free flame retardant compounds for wire and cable
Problems Solved
Effectiveness of compatibilizers in polypropylene and polyamides filled with mineral fillers, glass, or cellulose fibers Adhesion problems of polypropylene or polyamide products to nonpolar substrates Added cost of using compatibilizers, dispersing agents, and processing aids in wire and cable compounds
Applications
Tie-layer component between multilayer polar and nonpolar materials Wire and cable compounds using halogen-free flame retardants Glass-, mineral-, or cellulose-fiber-filled polypropylene Polypropylene–polyamide blends
