Silent Feet uses an advanced polymer technology to
absorb vibrations caused by appliances such as refrigerators and washing
machines. The material, called Sorbothane, is said to have achieved shock
absorption levels of up to 94.7 percent.
Sorobothane is a thermoset,
polyether-based polyurethane that has a high damping coefficient and maintains
its property over a wide temperature range. Its unique effectiveness derives
from the fact that it's a solid that flows like a liquid under load and retains
excellent memory. Other polyurethanes and rubber are one-dimensional under
load. Sorbothane's visco-elastic properties mimic human flesh. The elastic
properties of rubber return energy to the system. The material is custom molded
using the resin transfer molding process at Sorbothane's manufacturing location
in Kent, Ohio.
Another interesting aspect of the process is its use as a middle, or
"constrained" layer, between two structural layers, or as an "extensional"
layer on top of a structural layer. It's produced in a durometer range from 25
to 85 Shore "00" Scale.
Sorbothane, first developed in
1982, has been widely used as a shoe insole, as well as for a variety of
engineering applications. Silent Feet are newly engineered pads that feature
two "easy-slide" rear feet and two "super-sticky" front feet.
From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
