ExxonMobil - Polyethylene Products Exact™ Plastomer Resins for Film Packaging Exact™ 4056

Exact,Ñ¢ 4056, also known as Exxtra,Ñ¢ Seal POP 2283, is an ethylene-based hexene plastomer designed for film packaging applications. It is produced using ExxonMobil Chemical's EXXPOL¬Æ Catalyst Technology and can be blended with polyolefins to enhance heat sealing performance and toughness. This resin is suitable for dispersible film and batch inclusion bag applications. The typical density of Exact,Ñ¢ 4056 is 0.883 g/cm¬=, with a melt index of 2.2 g/10 min at 190¬8C under a load of 2.16 kg. The peak melting temperature is 164¬8F (73¬8C), and the Vicat softening temperature is 134¬8F (56.6¬8C). In terms of film properties, it exhibits a tensile strength at yield of 380 psi (2.6 MPa) in the machine direction (MD) and 300 psi (2.1 MPa) in the transverse direction (TD). The elongation at break is 490% MD and 640% TD, indicating good flexibility. The product also demonstrates notable impact resistance with a dart drop impact value of 620 g and tear strength values of 90 g MD and 250 g TD. It has a gloss of 79 and a haze of 2.5%, which may be relevant for applications requiring specific optical properties. Engineers considering this product should note that it is not intended for medical applications and should verify compliance for potential food contact applications with ExxonMobil Chemical representatives.
