A new bathroom scale from Tanita is powered with solar cells
and is made from a new biobased plastic.
Tanita introduced solar-powered scales in 1986, but the
plastic is all new. "The addition of ABS plastic using biodegradable resins as
the primary construction material is an added bonus for our green consumers,
further protecting our environment and landfills," says Heather Bundgaard,
director of marketing, Tanita Corp. of America.
The new material, which was developed in Japan by
Unitika, is said to have improved properties in areas such as moldability,
transparency and flame retardancy. Called Terramac,
the plastic has thermal properties, durability and impact resistivity
comparable to ABS resins, a crossover plastic between commodities and
The first product made with the resin is the housing for the
bathroom scale HS-302,
nicknamed ECO Living, The pitch is that the Terramac resin decreased carbon
dioxide emissions 20 percent compared with the previous housing made only with
a petroleum-based plastic.
Unitika developed the first commercially available
heat-resistant PLA sheet in 2002. Flame retardance and impact resistance were
improved by applying Unitika's nanotechnology, plant-based reinforcements, and inorganic
fillers. Various polymer alloys further improve properties of the new material.
Unitika says it will expand this new alloy to toys and
electronic products. Also coming are films, sheets, fibers, and non-wovens. The
company's sales target for the new material is Β₯80 million ($875,000) by 2011.
One candidate as an alloying material is a new thermally
conductive nylon developed by Unitika Up until recently, compounds with
thermally conductive fillers were used to dissipate heat in miniature
electronic devices, but their processability is generally poor. "We often find difficulty in applying them
for small-size molding," says a Unitika spokesperson. "We have studied polymer
structure, the filler(s), and compounding conditions to clear the hurdle."
Unitika says the new nylon shows the same processability as
60 percent glass-reinforced nylon resin, while also exhibiting 50 W/mK thermal
The Unitika Group started in 1889, with the founding of
Amagasaki Spinners, the first company in Japan's textile industry. One of
its early plastic products was Emblem, a biaxially oriented nylon 6 film.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
