Westlake Epolene® N-21 Nonemulsifiable - Low Molecular Weight Polyethylene Polymer
Categories:	Polymer; Thermoplastic; Polyethylene (PE)
Material Notes:	Product Description: Epolene N-21 is a medium density polyethylene that improves slump resistance in cable filling and flooding, provides lubricity in printing inks, and can be used as a viscosity modifier in hot melts. Its higher melt point and hardness, compared to other Epolene Ntype polymers, provides improved resistance to solvents and oils. Key Attributes: Higher melt point and hardness provides improved resistance to solvents / oils Improves slump resistance in cable filling and flooding Medium density polyethylene Provides lubricity in printing inks Useful as a viscosity modifier in hot melts Application/Uses: Building and Construction Hot Melt Adhesives Packaging Solventborne Adhesives Wax Modification Wire and Cable
