Is Polyurethane Harmful To Human Health

The full name of polyurethane is polyurethane, abbreviated as PU. It is a copolymer monomer polymerized from toluene diisocyanate, which has good oil resistance, toughness, wear resistance, aging resistance, and adhesion. Polyurethane is generally used for foamed plastics, elastomers, fibers, surface coatings, etc., and will not cause harm to human body under normal conditions. If inhaled in large quantities, it can irritate the respiratory tract and cause respiratory diseases or asthma.
If inhaled or ingested by mistake, high concentration polyurethane can cause type I and III allergic reactions or cellular immune responses in the human body. Patients may experience diffuse wheezing in the lungs, pulmonary ventilation dysfunction, difficulty breathing, etc., which can lead to diseases such as bronchitis, bronchopneumonia, and even pulmonary edema, as well as asthma or allergic pneumonia.
Once a large amount of polyurethane is accidentally inhaled, it should be treated immediately under the guidance of a doctor. Mild dyspnea patients can be treated with aminophylline and prednisone; Patients with moderate dyspnea can be treated with intravenous corticotropin; Patients with pulmonary infection can be treated with cephalosporins, such as cefazolin, cefradine, and cephalexin. The above drugs should be used according to medical advice and should not be used without authorization to avoid adverse reactions.
