According to the latest statistics, as of August, China’s domestic production capacity for MDI (diphenylmethane diisocyanate), a key raw material for polyurethanes, has risen to 3.02 million tons per year. The use of polyurethane materials in the automotive industry is on the rise. The increase in the use of polyurethanes is closely linked to the rise in sales within the global automotive industry. According to incomplete statistics, China’s automobile sales reached 23.4919 million units in 2014, representing a year-on-year increase of 6.86%. Among the plastics used in modern automotive materials, polyurethane not only accounts for the largest proportion but also has an unparalleled range of applications – from vehicle interiors to exterior components, from soft materials to hard ones, from lightweight types to dense ones, all the way to high-strength fiber-reinforced products; polyurethane can be found everywhere. Polyurethane materials for car roofs are subject to the highest requirements among all polyurethane materials used in vehicles, especially as they now need to be used in conjunction with air duct folding machines. To meet the requirements regarding the hardness and rigidity of the substrate during the edge-sealing process with a duct folding machine.
