Tecothane™ Soft AR-65A TPU: Lubrizol announces the launch of Tecothane™ Soft AR-65 TPU, a medical-grade thermoplastic polyurethane that gives engineers a new option at the flexible edge of interventional-device design. The material combines very soft 65A performance with chemical resistance, thin-wall processability, and the manufacturing versatility of a 100% TPU.
Designed for neurovascular, peripheral vascular, and cardiac delivery catheters, Tecothane™ Soft AR-65A supports design opportunities that benefit from both material softness and processing versatility. Its properties can help enable softer distal sections, slimmer profiles, and complex device architectures while supporting the processing and integration required for reliable manufacturing.
Performance Benefits
Tecothane™ Soft AR-65A TPU: Advantages in Medical Device Applications
- Very Soft. 100% TPU: Reaches 65A Shore hardness without blending or additives.
- Chemical Resistance Beyond Softness: Demonstrates excellent chemical resistance to support catheter performance during use.
- Thin-Wall Processing Capability: Provides a material option for low-profile, highly flexible components where softness and manufacturability matter.
- Designed to Integrate: Supports established joining methods, including reflow, solvent, laser, and RF welding, for use in complex, multisegmented constructions.
- A Platform for Customization: Compatible with hydrophilic coatings and can be customized to address broader device requirements.
“Tecothane™ Soft AR-65A reflects Lubrizol’s commitment to helping device developers solve challenges across the full device architecture,” said Jennifer Green, Sr. Global Technical Business Development Manager. “Our medical TPU portfolio, including Tecothane™, Tecoflex™, and Pellethane® medical-grade TPU, offers designers material options for the performance, manufacturability, and design requirements needed for next-generation medical devices.”
Tecothane™ Soft TPU debuts at MD&M Midwest 2026 in Minneapolis, Minnesota, October 28–29, where Lubrizol will showcase its latest medical solutions and innovations.
