Stabilizers are added during the production of PVC, but the stabilizers are classified as non-toxic and toxic. Only when toxic stabilizers such as lead salts are added, will there be hidden dangers.

When consumers choose PVC materials, it is best to go to the formal building materials market with reliable reputation and quality, and ask the supplier to issue a test report. Consumers should pay attention to check the relevant documents and signs, and products that have obtained the "Hygiene License for Hygiene and Safety Products Related to Drinking Water" are safe.
