POE Polymers Overview - ExxonMobil POE 8203

Today, with the rapid development of polyolefin elastomers (POE polymers), ExxonMobil POE 8203, as an eight-carbon POE material with multiple performance advantages, has demonstrated extremely strong adaptability in multiple industries with its flexibility, transparency and low-temperature toughness. From high-strength flexible films to cable insulation, from automotive interiors to functional foam materials, POE 8203 is no longer a "traditional modified additive", but one of the core materials driving innovation.

01 | POE polymers properties: The "Way of balance" where softness and toughness coexist

POE 8203 is an octa-carbon olefin copolymer produced by solution polymerization technology. It has a uniform structure and orderly arrangement of molecular chains, which makes it show significant advantages in the following aspects:

  ・Extremely high elongation (2000%) : It demonstrates super strong ductility, especially suitable for sealing films and elastic layers that require high deformation.

  ・Outstanding softness: With A Shore A hardness of 85, it has a rubber-like feel but also possesses excellent tensile strength (22 MPa).

  ・Excellent low-temperature performance: Even at -40°C, the notched impact test shows no cracking (NB), and the embrittlement temperature is as low as -75°C, making it suitable for applications in extremely cold environments.

  ・Mild thermal performance: With a melting point of 72°C, it is suitable for medium and low-temperature processing systems, and the average melting heat reaches 100 J/g, providing better energy consumption control.

  ・Stable dielectric properties: The extremely low dielectric constant and loss factor make it an ideal low-voltage insulating material.

02 | Key advantage: Evolution from "modifiers" to "functional materials"

POE 8203 is not merely a formula ingredient used to "enhance flexibility". It has been regarded by an increasing number of enterprises as part of the functional structure:

  ・High transparency and low haze (2.4%) make it suitable for film packaging with high visual aesthetics requirements.

  ・High processing adaptability: Whether it is extrusion, blow molding or extrusion coating, a uniform surface and ideal thickness control can be achieved.

  ・Strong puncture resistance: Especially suitable for applications such as stretch films and transport protective films that have high tolerance requirements for mechanical damage.

  ・Good thermal stability and environmental stress cracking life (1000 hours) : Suitable for long-term outdoor usage scenarios, such as roof waterproof membranes, tunnel linings, etc.

03 | Innovative application scenarios: The diversified future of POE 8203

Thanks to its balanced mechanical properties and excellent low-temperature elasticity, POE polymers 8203 is being widely applied in the following innovative scenarios:

  ・PP modification and toughening: Endows rigid materials with flexible buffering performance and is an ideal flexibility regulator for halogen-free flame retardant systems.

  ・Eco-friendly foam and cork stopper alternative materials: Sustainable foam solutions for replacing PVC or TPR.

  ・Extruded coating materials: Provide a soft yet tear-resistant protective layer on textile film layers and construction fabrics.

  ・Synthetic cork stoppers and functional insole materials: Combining excellent resilience and processing molding properties, expanding the boundaries of consumer products.

04 | Key Performance Data of POE 8203

05 | Application suggestions and processing key points

  ・Suggested processing temperature: It is recommended that the melting temperature be controlled within the range of 150 to 180°C to ensure that the flexible structure is not damaged.

  ・The recommended addition amount when blending with PP or EVA: According to the target flexibility and impact requirements, it can be controlled between 15% and 40%.

  ・Molding precautions: It is recommended to use processing stabilizers and antioxidants in combination to extend the processing window and avoid yellowing.

06 | Why choose POE 8203?

  ・Want to enhance flexibility without sacrificing transparency and appearance?
