Foam is Everywhere...
All Foam is Not Created Equal
Flexible polyurethane foam is one of the most versatile materials ever created. We are literally surrounded by it in our lives. It's used as packaging material to protect delicate instruments and it is the cushioning material of choice in almost all furniture and bedding.
Foam has become such a widely used material because it provides a unique combination of form and function. It's light, quiet, mildew resistant and foam won't aggravate common allergies. With the right equipment, foam can easily be cut or moulded into almost any shape. At the same time, foam can be made to provide very supple or very firm cushioning for any given application. Flexible polyurethane foam appears to be a simple product, but it is actually very complex. It can be produced to have an almost infinite variety of properties. Even though two foams may look the same, they may feel and perform entirely different.
However, the properties of foam can be identified and specified very precisely. The foam industry utilizes a number of measurements and tests to accomplish this. Using these measurements, it is possible to pinpoint the right foam for the right applications (Foam Grades).
