Announcements of new polymers are infrequent, with most of the action coming in additive systems that enhance performance or processability. DSM Engineering Plastics says it has developed a “breakthrough” polymer called PA4T, a specialized nylon aimed at electronics miniaturization. Specific attributes include excellent dimensional stability, compatibility with lead free soldering, high stiffness and mechanical strength at elevated temperatures, high melting point, and excellent flow and processing window. Potential applications include memory card connectors, CPU sockets, and air/fuel and power train components. A market development plant in the Netherlands will open early next year.
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
