Dyman Foam’s website makes the manufacture of foam look easy – “similar to the making of bread”. Of course, the chemical process are entirely different since, obviously, we cannot eat foam. Besides, foam requires the use of other chemicals to begin with. Polyol and TDI are the basic components of foam. Catalysts, water and blowing agents are added into the mix in order to finally come up with the final product. The similarity with bread lies in the production of many tiny pores or air spaces within the foam which provides the cushion effect, just like fluffy bread.
But foam can also be hard, like bagels. Softness or hardness, together with weight, determines the quality of foam. Technical standards provide manufacturers a measure of the quality of foam. Just because a particular kind of foam is soft does not mean it is of good quality. The weight, aside from the softness, determines how foam performs. It is a simple measure of how much foam is contained and has an affect on the strength or durability of the end material.
As Dyman explains it, cheap foam can be made soft or hard; but it will remain of low quality. The weight or density of the foam is a rough measure of the quality of foam as we notice in terms of how heavy good foam is compared to the cheap kind. Likewise, we are informed that color has nothing to do with the quality of the foam. The color is merely added to distinguish between different types and densities of the foam.
Knowing the above basic info about foam will help buyers and users have better judgment when choosing what type of foam to purchase in the future. They will no longer be mere unconcerned or unaware users of foam, which we take for granted often as it is hidden from our sight, but discriminating and money-savvy consumers.
