Flexible polyurethane foams are often derived from polyglycol-based materials, reacting with diisocyanates to create their cellular structure. These foams exhibit a wide range of characteristics depending on the specific polyglycol used, including varying densities, compression properties, resilience, and tensile strength. For instance, a polyether polyol might yield a softer, more flexible foam suitable for cushioning, while a polyester polyol could result in a firmer, more durable foam appropriate for structural applications.
The tunable nature of these materials makes them valuable in numerous industries. Their ability to absorb energy, provide thermal insulation, and offer comfort has led to their widespread use in furniture, automotive seating, bedding, packaging, and insulation. Historically, the development of these foams revolutionized comfort and safety in many applications, replacing less versatile and often less safe materials.
