Producing plastics from fossil fuels emits a lot of carbon dioxide, but a new study finds the life cycle emissions are actually lower than glass and aluminum.
The technology exists to make a fully compostable, fully plant-based plastic product, but it is far more expensive than conventional plastics, and does not always work as well, especially if it is ...
When coated with a 50–100 nanometer layer of aluminum oxide, the material was able to withstand loads of as much as 280 megapascals, stronger than any other known material whose density was less than 1,000 kilograms per cubic metre (1,700 lb/cu yd), that of water.
The thermal grease 860 is a silicone oil with a Zinc Oxide filler and 8616 and 8617 are synthetic oils with various fillers including Aluminum Oxide and Boron Nitride. At 25 °C the densities are 2.40, 2.69 and 1.96 g/mL for the greases 860, 8616 and 8617 respectively.
The first artificial fibre reinforced plastic was a combination of fiber glass and bakelite, performed in 1935 by Al Simison and Arthur D Little in Owens Corning Company [15] One of the most common and familiar composite is fibreglass , in which small glass fibre are embedded within a polymeric material (normally an epoxy or polyester).
Aluminum can prices vary by region and are based on weight. The average recycling value per pound of cans in the U.S. is currently $0.56. How many aluminum cans are in a pound?
There is some overlap between MMCs and cermets, with the latter typically consisting of less than 20% metal by volume. When at least three materials are present, it is called a hybrid composite. MMCs can have much higher strength-to-weight ratios, [2] stiffness, and ductility than traditional materials, so they are often used in demanding ...
The aluminum construction keeps your drinks cold, even without any ice. We tested it to see how it compares with a classic Yeti cooler.
