Is PVC toxic? OK, yes you heard that right. Of course, not all PVC is poisonous, and the products that have been formally produced are generally not available. Therefore, it is required that everyone must choose a qualified and reliable manufacturer when purchasing PVC products, otherwise the consequences will be serious.

PVC production process

PVC sheet is a sheet made of PVC material. The main component of PVC is polyvinyl chloride, which has bright color, corrosion resistance, firmness and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process to enhance Its heat resistance, toughness, ductility, etc., so its products generally do not store food and medicine. It is a well-loved, popular and widely used synthetic material in the world today. Its global usage is the second highest among all synthetic materials.

How to distinguish whether PVC material is toxic or not

The first is to see whether the resin is a sanitary grease.

Second, look at the auxiliaries. A large number of auxiliaries should be used in PVC processing. The auxiliaries are both toxic and non-toxic, especially the stabilizer. The opaque ones are poisonous with lead salts, cadmium salts, barium salts, etc. poison. The same is true of other rib agents, both poisonous and non-toxic.

Therefore, PVC is non-toxic, but whether PVC products are toxic depends on the specific product and use. For example, PVC sheets are widely used in drug packaging, and disposable infusion tubes are all PVC. The thermal stability of PVC is not very good, and it is easy to decompose when heated, but the temperature should be at least about 170 degrees, and light will not cause PVC to decompose. At present, the drainage pipes used in construction are all PVC materials, so it is very unstable and extremely Inaccurate. Decomposition is to produce HCL, the smell is very pungent, generally only in the production process, not in use.

Therefore, it is very important to choose a PVC material selection company
