The ability to withstand broad temperature swings can be the undoing of many adhesive systems. There may be sacrifices in chemical resistance, ease of use, or bond strength. Master Bond of Hackensack, NJ, says it has developed a one-component epoxy that offers best-of-class bond strength and chemical resistance over a service temperature range from 4K (-452F) to 350F.
When bonding aluminum, for example, Master Bond says its Supreme 10HTFL offers tensile lap shear strengths exceeding 2,000 psi. Master Bond also says it performs well in ASTM D1876, the standard test method for peel resistance of adhesives (T-Peel Test).
“Its performance properties are at their most impressive when bonding substrates with wide differences in their thermal expansion coefficients,” says Robert Michaels, Master Bond’s vice president of technical sales. Target bonding applications include a variety substrates, including aluminum, steel, engineering thermoplastics, fiber reinforced composites, ceramics, glass, and wood.
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
As we saw on the show floor this week at the Pacific Design & Manufacturing and co-located events in Anaheim, Calif., 3D printing is contributing to distributed manufacturing and being reinvented by engineers for their own needs. Meanwhile, new fasteners are appearing for wearable consumer and medical devices and Baxter Robot has another software upgrade.
