The crosslink nature of this foam type causes it to try very hard to rebound to its original shape quickly, which has the effect of introducing a little bit of "bounce" in addition to offering shock absorption. There are three main grades of polyurethane foam. this foam is often referred to as "crosslink" or "crosslink polyethylene" foam. Polyurethane foam is a blanket term that includes any foam that is synthesized using polyol and diisocyanate. Polyethylene is a firm, closed-cell foam. Polyurethane foam, memory foam and latex foam are the three most common types of foam used in mattresses. Choosing polyurethane foam involves more than just looking at density; it’s important to select the right type of foam for the application. feet.
