We know that PVC is a PVC material, this material is a non-crystalline materials, non-crystalline plastic in the melting process without a fixed melting point and the appearance of transparent, our more common non-crystalline plastics, including PC and PVC. PVC itself is not toxic, but the vinyl chloride monomer used in the polymerization has a carcinogen.

To distinguish whether the PVC material is toxic depends on whether the resin has a health grade grease, followed by PVC in the synthesis of processing to join a large number of additives, additives are also divided into toxic and non-toxic, with opaque lead salt, cadmium, barium Salt and other stabilizers are toxic, in addition to other stabilizers are basically non-toxic, and other additives are also divided into toxic and non-toxic!
