It is difficult to go one day without coming across some sort of flexible polyurethane foam. It is one of the most versatile materials ever created and found virtually everywhere in our modern world. It is in our cars, disposable packaging of fast food, and the cushioning of our furniture, bedding, and insulation material. Each year, a molded foam manufacturer company contributes to the 1.7 billion pounds of this material produced and used in the U.S. History Polymer varieties were first made from the 1930s to 1940s with polystyrene being the first polymer foam in 1931. Invented by Dr. Otto Bayer at the start of World War II, polyurethane was first used as a replacement for rubber and as a coating to protect other common materials at the time, such as metals and wood. A few years following the war, the flexible polyurethane version was invented, and it made its debut by a molded foam manufacturer as being utilized for cushioning in furniture and the automotive industry. The following two decades increased the popularity of polymers as new technologies developed. New methods, such as injection molding, twin screws, and several extrusion techniques were introduced. Unique Qualities Foam has become such a widely used material due to its unique combination of form and function. It is light, resists mildew, and does not aggravate common allergies. A molded foam manufacturer can easily cut or mold it to almost any shape. Additionally, it is made to provide very flexible or extremely firm cushioning in any given application. This incredible versatility can be found in the support of long-term medical confinement devices, or in the comfort of our living room furniture cushioning. Although its appearance may lead you to believe it is a simple product, it is actually quite complex. A molded foam manufacturer can produce it to have an almost infinite variety of properties. Moreover, even though two may look exactly alike, they may feel and perform entirely differently. Key Ingredients To All Applications While a number of various measurements and tests may be used to choose which variety of foam to use in a specific product, almost every selection task has either one or all of the following three elements as its final objective: -Support: It has to be able to support the right amount of weight for proper cushioning of an object or person. -Comfort: It must feel comfortable for the user and provide comfort not only as cushioning, but also for intent of use. -Durability: It must hold up throughout the duration of use without losing its original properties. If the needs in each of those three areas are evaluated first, then selecting the ideal variety for any given use becomes much easier. For example, a sofa seat cushion should have good support, comfort, and durability. To learn more about their options for molded foam, a manufacturer should visit http://grft.com/?page_id=36.
