This formaldehyde-free tape system is part of Adchem's 300 series. It uses the quick-stick properties found in rubber-based systems and the temperature performance of acrylic systems. It offers maximum performance at a lower price, with a differential caliper coating of 1.7 mils on the exposed side and 1.3 mils on the liner side, and typical peel values of 72 oz-inch width on the exposed side and 64 oz-inch on the liner side. It has many liner options including 55-lb densified Kraft, 74-lb polycoated paper, 12-point board and a 2-mil PET liner. It is made for substrate-bonding applications, and is useful for low surface energy materials and foams such as cross-linked polyethylene, low perms, ethers and esters.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
