Film and Extruded Sheet Performance
ENGAGE HM 7289 POE Resin is designed for film and extruded sheet applications requiring high flexibility, elasticity, and high melt strength. Its unique olefinic composition also supports improved processability and material handling.
The material provides good elastic recovery and impact performance, making it suitable for flexible structures where repeated deformation, toughness, and dimensional recovery are important.
The melt index of less than 0.50 g/10 min and Mooney viscosity of 74 MU support the high melt strength positioning of ENGAGE HM 7289. These rheological characteristics can be useful in extrusion processes where melt stability and structural control are important.
ENGAGE HM 7289 POE Resin provides strong extruded sheet mechanical performance. The TDS reports tensile strength values of 14.1 MPa across flow and 20.6 MPa in the flow direction, with elongation values of 650% and 670% respectively.
The extruded sheet tear strength data also show directional values of 65.0 kN/m across flow and 68.0 kN/m in the flow direction. Customers should consider specimen preparation and test direction when comparing these values with other materials.
Actual extrusion temperature, screw configuration, die design, draw ratio, cooling conditions, sheet thickness, orientation, and formulation should be optimized according to production equipment and final product performance requirements.
Customers should evaluate ENGAGE HM 7289 POE Resin under actual extrusion, film or sheet structure, and end-use conditions before commercial production.
