ViscoSchaum
ViscoSchaum is a viscoelastic polyurethane foam, commonly marketed in German-speaking markets as memory foam. It deforms under prolonged pressure and body heat to conform to the body, then slowly returns to its original shape when pressure is released. The material’s name reflects its viscoelastic behavior: stiffness decreases with warmth and time under load.
Manufacture and structure: ViscoSchaum is produced by reacting polyols with diisocyanates to form polyurethane foam with
Applications: It is widely used in bedding products such as mattresses, toppers and pillows, as well as
Advantages and limitations: Benefits include conforming support, good pressure relief, and reduced motion transfer. Limitations can
History and naming: ViscoSchaum mirrors the memory-foam trajectory, with NASA research in the 1960s and consumer
