Plastic electronic skin could give sense of touch
Plastics & Rubber Weekly    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Research engineers at the University of Illinois at Urbana-Champaign have developed novel skin-mounted electronics using a polymer substrate. Components for sensing, medical diagnostics, communications and human-machine interfaces can be combined on a plastic patch thinner than a human hair. This mounts directly onto the skin "with the ease, flexibility and comfort of a temporary tattoo." More


Improved mechanical properties of a polylactide thermoplastic elastomer
SPE Plastics Research Online    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Thermoplastic elastomers are very useful materials in packaging and appliance applications. A primary advantage is their amenability to injection molding, a common process for manufacturing both small and large commercial components. High cost and poor physical properties, such as low thermal stability, are common disadvantages of thermoplastic elastomers. Poly(lactic acid), PLA, may overcome these disadvantages. PLA is a biodegradable aliphatic polyester that is both biodegradable and renewable: lactic acid can be produced by microbial fermentation of biomass. More

Chemical degradation of polyethylene pipes due to water-based disinfectants
SPE Plastics Research Online    Share    Share on FacebookTwitterShare on LinkedinE-mail
Polyethylene is commonly used to make domestic water pipes. It's clearly important to maintain pipe integrity, and so doing requires understanding of the chemistry underlying PE pipe fracture due to chemical aging, such as corrosion by disinfectants. We can analyze the problem using some basic equations. A PE pipe transporting water at temperature T and pressure p, inducing a hoop stress σ, is expected to undergo a failure after a duration tf. Only hoop stresses lower than a critical value on the order of 10MPa are used in practice. More

From cows to plastic car parts
Edmonton Journal    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Using steam and pressure, a University of Alberta research lab is extracting protein material from waste animal carcasses that is eventually converted into a variety of plastics. While a "mooving" car may sound like science fiction, David Bressler and his team are currently using thermal hydrolysis - a process that breaks down complex molecules - to make the thick goo for testing by the Woodbridge Group, an automotive parts manufacturer that specializes in polyurethane and makes items such as plastic mouldings and headliners.

New polymeric material brings companies one step closer
to cheaper plastic solar cells and electronics

PhysOrg    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A single polymer that can be used in both new age plastic electronics as well as plastic solar cells could spell greater cost-savings and open up new design options for electronic and solar cell companies. A*STAR's IMRE has developed a new polymer that not only produces a high charge mobility of 0.2 cm2/V.s, which is the same value achieved by commercially available semiconducting materials but also has a high solar power conversion efficiency of 6.3 percent.

Polymer prices fall on low crude, naphtha prices
Business Standard    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Polymer prices, after rising for less than a month, fell once again in the domestic market following low crude oil and naphtha prices globally. Industry sources said the falling crude price has led to a drastic decline in naphtha prices around the globe. While crude prices have come down to $86-88 a barrel, naphtha prices are hovering around $860-870 a ton. This is as against a high of $110-115 a barrel for crude, which had propelled naphtha to touch a peak of $1,000 a ton few weeks before. More
