Density: 0.864 g/cm³
Melting Point: 100°C
✅ Very Low Viscosity
Vistamaxx 8380 is a very low viscosity propylene-based elastomer primarily composed of isotactic propylene repeat units with random ethylene distribution, produced using ExxonMobil’s proprietary metallocene catalyst technology. This grade is supplied in pellet form and enables enhanced flow characteristics that can lead to processing efficiency and cycle time improvements in hot melt adhesives, extrusion, and injection molding applications. Suitable for industrial applications requiring low viscosity and high flow.
With a viscosity of 7570 mPa·s at 190°C and a melting temperature of 100°C, Vistamaxx 8380 delivers exceptional flow and thermal stability, making it a preferred choice for formulators seeking to reduce melt pressure, improve filler dispersion, and increase throughput in adhesive and compounding systems.
This grade offers excellent compatibility with a broad range of polyolefins, including PP and PE, and can be used as a process aid or viscosity modifier in extrusion and injection molding applications. Its very low viscosity helps improve flow characteristics, reduce energy consumption, and enhance cycle time performance in suitable systems.
Designed for versatility, Vistamaxx 8380 can be used as a key performance additive in hot melt adhesive formulations where low viscosity, substrate wetting, and balanced adhesion are critical, or as a processing aid in compounding and extrusion applications.
