Types of foam

Different grades of foam are produced by varying proportions and types of ingredients and processing conditions, with each grade designed to suit specific applications.

Even though two foams look exactly alike, 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. By using these measurements, it’s possible to pinpoint the right foam for the right application.

The type or grade of foam is identified based on an Australian Standard classification, eg AA23-130, where each symbol has the following significance:

AA		Tells us the foam type or brand.
23		This means the average density of this grade is 23 kg/m3.
130		This defines the hardness of the foam in Newtons.
