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.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
Plastic bags can become useful as either raw materials for plastics or feedstock for fuel. It's when they're not recycled that they become a major problem. That's what California's bag ban will prevent.
