Is the plastic barrel of antifreeze toxic

- Aug 07, 2019-

Polyvinyl chloride is also a commonly used plastic. It is a resin composed of a polyvinyl chloride resin, a plasticizer and an antioxidant, and is not toxic by itself. However, the main auxiliary materials such as plasticizers and anti-aging agents are added, and the plasticizers in daily-use polyvinyl chloride plastics mainly use dibutyl terephthalate and dioctyl phthalate. These chemicals are mainly used. Both are toxic, and the lead acid stearate of polyvinyl chloride is also toxic. Lead-salt-containing polyvinyl chloride (PVC) products in contact with ethanol, ether and other solvents will precipitate lead. When the lead-containing polyvinyl chloride is used as a food packaging and meets fritters, fried cakes, fried fish, cooked meat products, and cake snacks, the lead molecules will diffuse into the grease, so PVC plastic bags cannot be used. Foods, especially foods containing oil. In addition, polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at a relatively high temperature, such as about 50 ° C. This gas is harmful to the human body, so PVC products should not be used as food packaging.

Polyvinyl chloride plastic products will slowly decompose hydrogen chloride gas at a relatively high temperature, such as about 50 degrees. This gas is harmful to the human body, so polyvinyl chloride products should not be used as food packaging. Bakelite (phenolic plastic) contains free phenol and formaldehyde, which is harmful to human body and is not suitable for storing food and packaging for food. Although electric jade (urinary aldehyde plastic) is odorless and tasteless, it can be precipitated in 100-degree boiling water or used as a vinegar-containing food, which is harmful to human body, so it is not suitable for food or food packaging. Renewables of waste plastics (some may add a little new material), because of their complex composition, it is difficult to ensure that they are not toxic, so they are generally not used as food containers and packaging materials.
