A phthalate (plasticizer) free, very stretchable thermoplastic polyurethane (TPU) alloy promises to offer enhanced product design and application parameters for medical product and other designers and manufacturers. With a vertical elongation of 800% and higher plus a high tensile strength, the Neuthane soft-grade N8511 H Series of TPU alloys make the new material ideally suited for applications that include disposable thin-wall extruded tubing used in laparoscopic surgery procedures. Favorable stretch characteristics enable instruments of various sizes to be inserted into the molded product. Shore A hardness can be between 65 or 75, depending on the formulation, giving the end product an additional benefit—preferred softness.
