Polyurethane material for top car materials
According to the latest statistics, as of August 2015, the domestic production capacity of polyurethane raw material MDI (diphenylmethane diisocyanate) has soared to 3.02 million tons per year. The consumption of polyurethane materials for automobiles is in a stage of rising.
The increase in polyurethane consumption is inseparable from the increase in sales in the global automobile industry. According to incomplete statistics, my country's automobile sales reached 23,491,900 in 2014, a year-on-year increase of 6.86%. In the plastics used in modern automobile materials, the amount of polyurethane is not only the largest, but also its application range is unparalleled, from the car box to the outer parts, from soft to hard, from light to dense, all the way to high High-strength glass fiber reinforced products, polyurethane applications can be seen everywhere.
The polyurethane material for automobile roof is the most demanding among all polyurethane materials for vehicles, especially now it needs to be combined with a duct folding machine to meet the hardness and rigidity requirements of the substrate during the hemming process of the duct folding machine.
