Memory foam seems to be one of the newest products on the market. It is a combination of viscous and elastic properties, meaning it flows like honey and bounces back to its original shape like elastic. The best, and most expensive, mattresses on the market are made from this substance. However, it is not new or just for mattresses. The History Behind the Foam Foam is simply a gas trapped in pockets of liquid or solid material. It is the word used to describe the white stuff on top of a beer and the pliable packing material used to ship delicate valuables. It is created by pumping gas through a solid material like rubber or latex, which results in a whipped-up version. Originally made from natural latex derived from the rubber tree, latex foam gained popularity in the 1940s as a padding material for everything from safety equipment to medical devices. In the 1960s, NASA created the visco elastic version as a safety material. NASA released the formula to public domain in the 1980s, which is when the mattress industry picked it up. Modern Day Uses and Applications Today, memory foam is a popular material for mattresses, but it has many other applications. This substance can be used for seat cushions in cars or on furniture. It is more durable than traditional latex foams, and retains its shape longer. Visco elastic manufacturers are getting involved with sports equipment and shoe production, as well as keyboard wrist pads and the soft covering on earbuds. Visco elastic can be used anywhere a soft, padded surface is needed that will fit to a particular form. Other applications for this soft dense material include acoustics products like sound-dampening liners and soundproof walls. Toys are another fun application. Toy designers know they can count on this material to regain its original shape. They also know that it is soft enough to bounce off a small child without doing any damage. Determining Quality Manufacturers use formula variations of this product for various applications. Visco elastic foam is typically classified by density. The density is much higher than that of any traditional latex versions. Visco elastic foam manufacturers must use specialized equipment to measure and cut the substance because of its rate sensitivity. As a result, the cutting process is much slower with this versatile substance. When shopping around for mattresses or other products, you want to be sure you are comparing prices along with density and thickness. The stability of this substance is partly dependent on the thickness of the piece. A four-inch-thick piece used for a mattress topper may have the same density as an eight-inch-thick mattress, but it won't offer the same support. Visco elastic is the latest version of foam to be used for a variety of products, from safety equipment to medical devices. Developed by NASA, it offers a unique combination of properties. You might be surprised to realize how much of this substance you rely on in your daily life. When looking for visco elastic foam manufacturers, contact Grand Rapids Foam Technologies.
