Polyurethane (PU), invented in 1937 by Otto Bayer, began as a solution to a rubber shortage. Its versatility quickly led to widespread use in coatings and adhesives due to strong bonding properties. PU is created by reacting polyols with isocyanates, forming a foam that's modifiable in density and structure. Today, it's essential in industries such as construction, automotive, and refrigeration, improving energy efficiency and providing comfort. However, environmental concerns arise from its non-biodegradable nature, prompting initiatives focused on reducing PU waste and promoting sustainable alternatives.
Despite its versatility, PU foam comes with serious environmental challenges due to its non-biodegradable nature and high durability. Millions of tons of rigid PU foam are produced annually.
Its flexibility allowed PU to revolutionize industries with products like insulation and padding, used in construction, automotive, and refrigeration for their energy efficiency.
Originally designed as a cheap, versatile alternative to rubber, PU quickly became popular for its strong bonding and protective properties.
In construction, PU is used in panels and boards that reduce energy consumption and stabilize indoor temperatures, showcasing its essential role in modern industries.
