Is Pu Leather Harmful To The Human Body?

PU leather is generally harmless to the human body under qualified conditions, but may have harmful effects under certain conditions.

PU leather, or polyurethane synthetic leather, is a material widely used in fields such as clothing, furniture and automotive interiors. Its main component is polyurethane resin, which is stable under normal use, does not release harmful substances, and has no direct harm to the human body. However, it should be noted that:

If PU leather is under high temperature and high pressure, it may release substances such as formaldehyde and benzene, which are harmful to the human body. Long-term contact or inhalation may cause eye stinging, coughing, local rashes and other consequences.

In the production process of PU leather, certain chemical additives such as solvents and catalysts may be used. These chemicals have potential health risks if they are not completely reacted or remain in the finished product. In particular, toluene diisocyanate (TDI) is listed as a substance that may be carcinogenic to humans by the International Agency for Research on Cancer. If the production process is not properly controlled, the residual TDI may pose a health threat to consumers.
Therefore, when choosing PU leather products, you should pay attention to its quality and the reputation of the manufacturer to ensure that you buy qualified products. At the same time, maintain a good ventilation environment during use to reduce potential risks. For people with sensitive skin or a history of allergies, special attention should be paid to the selection and use of PU leather products to avoid causing skin discomfort or allergic reactions.
