POLYURETHANES: SUSTAINABLE MATERIALS
POLYURETHANES: SUSTAINABLE MATERIALSPOLYURETHANES: SUSTAINABLE MATERIALSPop-ula-tiongrowth, life expectancy, need forBy mixing the chemical raw- MATERIALS - polyols and diisocyanates in carefully formulated proportions and using transformation processes, ranging from the simple to the sophisticated,it is possible to make a wide variety of polyurethanes, includingrigid and flexible ARE POLYURETHANES?Polyurethanes have revolutionized the quality of life in the 20th Century, providing energy savings, safety,lightness, comfort and durability. Combining the skills of the designer, chemist and engineer, their unique properties can be adjusted to create valuable productsvarying in structure from soft furniture foam to tough car bumpers, each tailor-made for a specific are durable products, offering many years of service. Lifetimes can vary between 3 and morethan 50 years depending on the end use. An averagelifetime of 15 years for refrigerators (insulated withpolyurethane foam) is just one used in combination with MATERIALS such as textiles, metals, wood and other polymers, polyurethanesare not always visible in the end-product.
