Polyurethane sponge cushion Guaiwei poisonous
The odor produced by the free isocyanate monomer. The preparation of the main raw materials of polyurethane isocyanate, characteristics of the monomer has a low boiling point and high vapor pressure, easy to evaporate into the air causing air pollution, harm to human body. A lot of polyurethane products contain free isocyanate monomer, will slowly release in the process of using day after it.
Polyurethane cushion taste in general is amine smell more obvious, this comes from the polyurethane catalyst, excessive inhalation of organic amine is certainly harmful to the body, can be in sunny days in the air drying, extrusion, accelerate the volatilization of amine smell. As for formaldehyde exceed the standard in general, low odor in the sponge will appear, rarely used conventional sponge cushion products the catalyst content of aldehydes.
