The "tailor-made" nature of PU stems from its :
Polyurethane (PU) is a versatile group of synthetic polymers characterized by the presence of in their chemical backbone . First synthesized by Otto Bayer in 1937, these materials have evolved into a cornerstone of modern manufacturing due to their tunable properties, ranging from soft, flexible foams to rock-hard rigid plastics. 1. Fundamental Chemistry and Synthesis Polyurethane
Rigid foams serve as high-performance thermal insulation for roofs and walls, significantly reducing energy consumption. The "tailor-made" nature of PU stems from its
Long, flexible polyol chains that provide elasticity and low-temperature flexibility. ranging from soft
These segments naturally separate into distinct domains, giving PU a unique balance of toughness and extensibility. 3. Industrial Applications
