ExxonMobil Vistamaxx 8580 Very Low Viscosity Propylene Elastomer for Hot Melt Adhesives & Compounding
Density: 0.870 g/cm³
Ethylene Content: 10 wt%
✅ Very Low Viscosity
Vistamaxx 8580 is a high-performance propylene-based elastomer specifically engineered for very low viscosity applications. It is primarily composed of isotactic propylene repeat units with random ethylene distribution, produced using ExxonMobil metallocene catalyst technology. This grade is supplied in pellet form and serves as an excellent process aid and viscosity modifier for adhesive, extrusion, and injection molding systems. Fully compliant with global industrial regulatory standards (RoHS/REACH).
Vistamaxx 8580 offers exceptional flow characteristics and processing efficiency, making it a preferred choice for formulators seeking to reduce cycle times and improve productivity in adhesive and compounding applications.
This grade stands out for its ultra-low viscosity, which significantly improves flow characteristics, enhances processing efficiency, and reduces cycle times in suitable systems. Its low odor, low color, and non-corrosive profile make it ideal for sensitive adhesive formulations and high-quality polymer compounds. The product is thermally stable across a wide processing window and offers excellent compatibility with a broad range of polyolefins, including PP and PE.
Designed for versatility, this material can be used as a flow enhancer in extrusion, as a viscosity reducer in injection molding, or as a key performance additive in hot melt adhesive formulations, helping to achieve the right balance of tack, open time, and substrate wetting.
