TPU production and use

TPU production and use

Traditional TPU products are accomplished through the reactor. Because of its complex process, an area of large, serious pollution, has gradually sheet screw extruder and replaced by a twin screw extruder. Synthesis of polyurethane in the extruder or by reactive extrusion production of polyurethane elastomers, these reactions are by step-growth polymerization reaction mechanism of.
The reaction was often based on a melt extruder or liquid feed, chemical reactants molar ratio between the opposite for the production of high molecular weight polymers is very important. In mainland China and Taiwan markets, TPU maximum amount that the shoe aspects injection molding, and the German BASF and China Taiwan's main priority was to produce and suppliers. Taiwan Ure which has five factories, which TPU capacity ranks first in Asia.
Prior to the company's main European markets, but fought in mainland China, the market share is gradually increasing. It is reported that China gifted ready within five years to build three TPU plant, making a total capacity of more than 50,000 metric tons in 2008, ranking first in the world.
