Polyurethane foams are incredibly versatile. Polyurethane foam is characterized by its light weight, resilience, low odor, and high resistance to mildew. Polyurethane ester foam is an open-cell foam with excellent memory and very soft compression characteristics. It is used in many applications to provide protection, support, comfort, and safety. Polyester-based polyurethane is slightly more rigid and supportive than ether-based polyurethane. This is due to smaller cells being created during the forming process. The smaller cells have less surface area to bend and flex than ether. This produces a foam great for shock absorption with a supportive structure, and is a great way to protect items in transit.
Applications include automotive seating, display and cushion packaging, gaskets, retail items, medical, and protective packaging.
