The chairs used in many offices should be PU office chairs, so today I will talk about the material classification of PU office chairs . PU materials can be divided into dry polyurethane slurry and wet polyurethane slurry. In the application process of dry polyurethane slurry, the solvent in the slurry is evaporated by heating and evaporation. The solvent is mostly toluene and methyl ethyl ketone. The evaporated solvent cannot be recovered, which not only pollutes the environment but also causes unnecessary waste. Because the wet polyurethane slurry is processed by extracting DMF with water (the reason is that DMF has infinite solubility with water), it is more environmentally friendly, and the synthetic leather produced has good moisture permeability and air permeability, soft hand feeling, Plump, light, richer in the style and appearance of natural leather, so the development speed is extremely amazing.
