ETERNALAST® TPU (Thermoplastic polycarbonate-based polyurethane) is a material developed by UBE Corporation Europe for advanced technical applications in sectors such as packaging, protection, automotive, thermolamination, agriculture, construction, and industry. This TPU combines elastomeric properties with superior mechanical strength, outperforming alternatives like PA (Polyamide) and PO (Polyolefins).
Key features of ETERNALAST® polycarbonate-based TPU films include elastomeric behavior, with an extremely low tensile modulus and no yield elongation point, ensuring flexibility and adaptability. While its tensile strength is slightly lower than PA, it surpasses PO in this aspect, offering sufficient elongation for a variety of applications.
In terms of mechanical resistance, TPU excels in puncture tests, showing performance comparable to Terpalex, and in tear resistance, where it significantly outperforms PA and PO. Additionally, its impact resistance (measured via the Spencer test) is remarkably high, with fewer defects after retort processes.The balance between flexibility, wear resistance, and durability makes ETERNALAST® TPU an ideal choice for applications requiring high-performance materials.
In conclusion, UBE’s ETERNALAST® TPU represents an advanced and versatile solution for technical films, offering superior performance in mechanical resistance and durability without compromising flexibility. With this innovation, UBE reinforces its commitment to delivering high-quality materials for demanding technical applications.
