  Whether it is in daily life or industrial applications, the scope of application of PVC is very wide, and PVC material can be seen in many industries, especially some items in daily life, such as PVC table mats, PVC wood floors, PVC wall stickers, PVC curtains, etc. Is PVC poisonous?

  PVC is a kind of raw material, the chemical name is polyvinyl chloride, PVC in daily life is PVC plastic products, PVC is usually divided into soft PVC and hard PVC, like a game mouse pad, very soft: hard PVC Usually used for printing, packaging, outdoor decorative building materials, etc., rigid PVC usually has coils, sheets, and plates. Into a whole piece of film, like fax paper, bag by bag.

  For PVC sheets, which are relatively thick, large companies usually sell PVC sheets of 0.15 mm to 2.0 mm.

  PVC itself is not poisonous! However, because the chemical reagents added in the production process, such as plasticizers, antioxidants, and other key auxiliary materials are toxic, usually the plasticizers added to PVC are mainly dibutyl phthalate, phthalic acid Dioctyl esters, etc., these chemical reagents have certain hazards. The anti-aging agent lead stearate salt of PVC products is also harmful if it encounters ethanol, ether, and other organic solvents, it will cause chemical changes and lead to lead. If PVC-containing lead salt is used when food bags meet oily food, the molecular structure of lead will spread into the oil, so PVD packaging bags cannot contain food, especially food with oil. In addition, under the corresponding high temperature of PVC plastic products, the gas that is harmful to the body will slowly dissolve at about 50 degrees: hydrogen chloride, so PVC products cannot be used as food packaging bags.

  However, at present, many PVC products are free of dibutyl phthalate, dioctyl phthalate, etc., which are usually used for packaging boxes, daily life, decoration, table mats, and door curtains, and wooden floors. If the ambient temperature does not reach 50 ℃, it is not easy to cause harmful gases, and PVC also has certain characteristics: it is flame retardant, and these characteristics also make its application field wider!
