Solid Silicone Rubber Sheet suits high-heat applications.
2013-07-23 14:29:59| Industrial Newsroom - All News for Today
Available in 40–80 durometer in sheet thicknesses from 1/32–1 in. and up to 60 in. wide, Premlene™ has -80 to +450°F temperature range and suits applications where corrosion, erosion, abrasion, wear, and sliding are of concern. Commercial grade silicone material, customized to fit requirements, also exhibits UV/ozone and tear resistance. Properties include 60 pts hardness (ASTM D-2240), 750 psi tensile strength (ASTM D-412), and 80 ppi tear strength (ASTM D-624). This story is related to the following:Rubber Silicone Sheets

How stable is the East Antarctica ice sheet?
2013-07-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Summit Voice: The biggest ice sheet in the world may be more susceptible to a warming climate than previously believed. New evidence garnered from mud deposits suggests that the East Antarctica Ice Sheet may have experiences significant melting about 5 million years ago enough to raise sea level by about 60 feet worldwide, according to researchers from Imperial College London. The study, published last week in the journal Nature Geoscience, shows that there was repeated melting between five and three million...
East Antarctica's ice sheet not as stable as thought
2013-07-22 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceNOW: Earth continues to hit temperature and greenhouse gas milestonesjust a couple of months ago, multiple stations measured carbon dioxide concentrations in the atmosphere of 400 parts per million, the highest in several million years. Many studies have tried to estimate how much and how rapidly the two great ice sheets covering Greenland and Antarctica might meltand the one reassuring point has been the apparent relative stability of the eastern (and, by far, larger) half of the Antarctic Ice Sheet....
Shift in Melting Pattern of the Greenland Ice Sheet Likely to Occur
2013-07-10 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Nature World News: Surface ice melt will become the new form of dominant ice melt in Greenland as outlet glaciers retreat inland, leaving ice production in second place, according to a new study. The Greenland ice sheet is often considered an important potential contributor to future global sea-level rise over the next century or longer: in total, levels would rise by more than 23 feet (seven meters) if it completely melted, scientists estimate. Changes in its total mass are governed by both fluctuations in melting...
Isotope Fact Sheet Warrants a Close Look
2013-07-10 06:00:00| Chemical Processing
The U.S. Environmental Protection Agency (EPA) recently released a fact sheet (www.epa.gov/oppt/newchems/pubs/isotopes.pdf ) on reporting chemical substances that contain different isotopes of the same elements listed on the Toxic Substances Control Act (TSCA) Inventory. The document has enforcement consequences so stakeholders should review it carefully.
