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.
At the JEC Europe 2015 composites show in Paris last month, makers of composite materials, software, and process equipment showed off their latest innovations. This year's show saw some announcements related to automotive applications, but many of the improvements came in the world of aerospace.
The DuPont-sponsored Plastics Industry Trends survey shows engineers want improved performance in a broad range of plastics and better recycling technology. These concerns top even processing enhancements that improve productivity.
Plastics leader SABIC recently announced a global initiative to help its customers take advantage of additive manufacturing (AM) and also advance 3D printing (3DP) technologies in several application areas. The company's plans go way beyond materials, and also include design, processing, and part performance.
A theme that was reflected in several ways at NPE 2015 was the use of 3D printing to assist in, or improve on, injection molding, as well as improvements in 3D printing materials and processes that are making better functional prototypes and end-use parts.
