Tolerathane™ TPU is a medical-grade thermoplastic polyurethane designed for long-term implantable device applications.
The material offers strong resistance to oxidative and hydrolytic attack while maintaining softness, durability, and processability.
It supports miniaturized device design in applications such as neuromodulation, cardiac leads, catheters, and implanted textiles.

As implantable medical devices continue to shrink in size and grow in complexity, manufacturers need materials that offer exceptional biostability, long‑term durability, and design flexibility. Lubrizol’s Tolerathane™ TPU meets these advanced

requirements by delivering a next‑generation medical-grade thermoplastic polyurethane engineered specifically for the demands of long-term implantation.

Tolerathane™ TPU provides superior resistance to oxidative and hydrolytic attack compared to currently available TPU materials, enabling longer material lifespan in harsh biological environments. It maintains softness without sacrificing physical integrity over time, making it well suited for applications such as nerve stimulation implants that require delicate tissue contact, minimally invasive placement and years of reliable performance. The material also integrates seamlessly with standard thermoplastic processing methods and offers tunable properties, giving designers greater flexibility as they innovate.

These combined advantages make Tolerathane™ TPU an excellent candidate for implantable technologies, including neuromodulation and cardiac leads, structural heart implants, percutaneous catheters, cables, and implanted textiles, all areas where thin-wall capability, miniaturization, and durability are essential.
