Coconut and Coir

Coconut and Coir Coconuts are not only something you can eat, but something you can sleep on. Coconuts are the fruit of the coconut palm (Cocos nucifera), a tree naturally found on tropical coasts. The coconut palm has spread by means of its bouyant seed floating on water, following ocean currents and tides. From beaches, it spreads to nearby low areas by dropped seeds. Coconuts are rather large and heavy for seeds, so coconut palms do not naturally range far from the shoreline. However,...

Polyethylene: The Safe Plastic

Polyethylene Penicillin was discovered by accident when Alexander Fleming noticed bacteria dying in the presence of certain molds. Vulcanization of rubber by sulfur was also accidentally discovered by Charles Goodyear. In 1898 in Germany, Hans von Pechmann accidentally synthesized polyethylene. It took longer for polyethylene to become widely used than for rubber and penicillin, but now it is one of the most widely used food packaging materials. And it is also being used in...

Gel

[caption id="attachment_461" align="aligncenter" width="400"] Technogel's gel tower layer[/caption]  Infusion of bedding foams with gel was first used in Europe, and is now widely used in the United States.  Gel infusion was first introduced to modify the support properties of the foam.  Later it was promoted as making memory foam cooler. What is gel? Gel can be called a semi-solid.  It is both solid and fluid.  The International Union of Pure and Applied Chemistry defines it as...

Mattress Foams – Part 2

(Continued from Part 1) The three major kinds of foam used in mattresses are polyurethane foam, visco-elastic memory foam, and latex foam. Each kind of foam has variations.  First, there are different ingredients in these foams.  Then there are different densities and firmness levels. Now gel is infused into different foams to add desired characteristics. Polyurethane Foam Polyurethane (PU) foam is made by linking large molecules, usually isocyanates, to each other with modified...
