Lubrizol has developed a thermoplastic polyurethane (TPU) urethane that targets replacement of silicone in peristaltic pumps. Peristaltic pumps are positive displacement pumps used to pump a variety of fluids. A technical officer of Lubrizol interviewed at MD&M West in Anaheim, CA yesterday said that the new TPU is melt processable, unlike silicone, which is a thermoset. The new material would be one of the softest TPUs with Rockwell Hardness of 62A. The product was on display at the Lubrizol booth. Full details are expected to be disclosed at the Annual Technical Conference (ANTEC) of the Society of Plastics Engineers in Boston this May.
NIST's new five-year strategic plan for its Material Measurement Laboratory lists additive manufacturing materials development as one of the main areas it will support by developing measurements, data, techniques, and models.
