Does pc necessarily contain bisphenol A, and does food grade PC material contain bisphenol A?

PC plastic cups do contain bisphenol A, but bisphenol A will only be chemically decomposed and released when it encounters high temperatures, so when you use PC plastic cups, as long as you avoid contact with hot water and do not heat it directly in the microwave oven or oven, it will not produce toxic and harmful bisphenol A. In short, plastic cups cannot hold hot water, so it will not cause harm to the human body.

Precautions for the use of PC plastic cups:1. The plastic drinking cup should be soaked in hot water several times before being used for the first time to remove the harmful substances that may be produced by the bottle.

2. When the ambient temperature is low when the plastic water cup is used, a small amount of hot water should be added to preheat the water cup to prevent the water cup from changing its structure and deteriorating its physical properties under the drastic temperature change.

3. Plastic is easy to become brittle at low temperature, so it is not advisable to use a water cup at low temperature or fall from a high place to prevent chipping.

4. Try not to use the water cup in extreme environments (such as high temperature exposure or microwave heating).

PC bottles contain bisphenol A, and there is no harm in using it correctly. PC bottles should not exceed 100 degrees Celsius, will not release BPA, generally such as big brands of bottles, such as Pigeon, etc., the content of BPA is lower than the international standard. It is better to sterilize with steam.

In fact, the country has not issued a ban on PC baby bottles, because there is no clear experiment to prove that the bisphenol A contained in the baby bottle causes harm to the human body. Like most of the plastic products we usually use, the BPA content is higher than that of baby bottles, and a small amount of BPA can be ingested through contact or breathing. According to official investigations, most of the body contains bisphenol A.

If you mind PC bottles, you can go for a PP or PPSU or glass bottle, which will definitely not contain BPA.

Yes. It is recommended to buy glass.

Bisphenol A is polycarbonate.

Plastics. Bisphenol A

Also known as BPA, it is used in industry to synthesize polycarbonate (PC) and epoxy resins.

and other materials. Since the 60s, it has been used in the manufacture of plastic bottles, cups for young children, and concealed plum coatings on the inside of food and beverage (milk powder) cans. BPA is everywhere, from mineral water bottles, medical celebration equipment to the inside of food packaging.

Every year, 27 million tonnes of plastic containing BPA are produced worldwide. However, BPA can also cause endocrine disorders, threatening the health of the fetus and children. Cancer.

and obesity due to metabolic disorders are also thought to be involved. The European Union believes that BPA-containing baby bottles can induce precocious puberty, and since March 2, 2011, the production of baby bottles containing the chemical BPA (BPA) has been banned.

Bisphenol A is one of the most widely used industrial compounds in the world, mainly used in the production of polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin and other polymer materials. It can also be used in the production of plasticizers.

Flame retardants, antioxidants.

Heat stabilizers, rubber antioxidants, pesticides, coatings and other fine chemical products.

In the manufacturing process of plastic products, the addition of bisphenol A can make it colorless and transparent, durable, lightweight and outstanding impact resistance, especially to prevent acidic vegetables and fruits from attacking metal containers from the inside, so it is widely used in the packaging of canned food and beverages, feeding bottles, water bottles, sealants used in dental fillings, spectacle lenses and hundreds of other daily necessities in the manufacturing process.

Bisphenol A, also known as BPA, is an organic compound.

Uses of Bisphenol A:

Bisphenol A is one of the most widely used industrial compounds in the world, mainly used in the production of polycarbonate.

Epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin and other polymer materials. It can also be used in the production of plasticizers, flame retardants, and antioxidants.

In the manufacturing process of plastic products, the addition of bisphenol A can make it colorless and transparent, durable, lightweight and outstanding impact resistance, especially to prevent acidic vegetables and fruits from eroding metal containers from the inside, which is widely used in the production of daily necessities.

Good evening, PC is polycarbonate similar to PET can be used as a normal food container, through the national certification of manufacturers to produce qualified PC without bisphenol A, it is also a kind of human health and environmentally friendly polyester varieties.

PC is a polycarbonate material, because the modern process of synthesizing polycarbonate needs to use bisphenol A and dimethyl carbonate, so there will be a certain amount of unreacted bisphenol A left in the bottle, the normal use temperature of this cup is generally -20 110 degrees Celsius, not exceeding the rated temperature range, the content of bisphenol A released is very low, almost negligible for adults, but the temperature is too high to say.

Introduction: Polycarbonate (PC) is a group of thermoplastic polymers containing carbonate groups in their chemical structure. The polycarbonate used in the engineering is a strong material, and some grades are optically clear.

They are easy to process, mold, and thermoform. Due to these properties, polycarbonate has many applications. Polycarbonate does not have a separate Plastic Classification Mark (RIC) and is classified as "OTHER" at 7 on the RIC list.

The main polycarbonate material is formed by the reaction of bisphenol A (BPA) and phosgene (CoCl2). The total reaction formula is as follows:

The first step in synthesis involves treating bisphenol A with sodium hydroxide, which deprotonation the hydroxyl group of bisphenol A.

hoc 6h 4) 2cme 2 + 2 naoh → na 2(oc 6h 4) 2cme 2 + 2 h 2o。

Diphenol salt (Na2(OC6H4)2CME2) reacts with phosgene to form chloroformate, which is subsequently attacked by another phenol salt. The net reaction of diphenol salts is:

na 2(oc 6h 4) 2cme 2 + cocl 2 → 1/n [oc(oc 6h 4) 2cme 2] n + 2 nacl。

This has not been done specifically, it has been soaked in boiling water for more than 10 minutes, and BPA can be dissolved by soaking in cold water for a week, but the higher the temperature, the greater the wear, the easier it is to release.

If the water temperature does not exceed 80 degrees, BPA will not be released.

It will be released at high temperatures for a long time, and the specific temperature is not specified.

Bisphenol A, also known as BPA, is industrially used to synthesize materials such as polycarbonate (PC) and epoxy resins. Since the 60s, it has been used in the manufacture of plastic bottles, cups for young children, and coatings on the inside of food and beverage cans.

BPA is everywhere, from mineral water bottles, medical equipment to the inside of food packaging. Every year, 27 million tonnes of plastic containing BPA are produced worldwide. However, BPA can also lead to endocrine disorders, threatening the health of the fetus and children.

Obesity due to cancer and metabolic disorders is also thought to be involved.

The European Union believes that BPA-containing baby bottles can induce precocious puberty, and has banned the production of baby bottles containing the chemical bisphenol A (BPA) since March 2, 2011.

Therefore, the plastic cup does not contain BPA, which proves that the raw material for the production of the plastic cup does not have BPA.

Bisphenol A, also known as BPA, is an organic compound with the molecular formula C15H16O2. Bisphenol A is mainly used in the preparation of epoxy resins (about 65%) and polycarbonate (about 35%), and its potassium or sodium salts are the raw materials for the production of polysulfone, and a small amount is used as a rubber antioxidant.

Bisphenol A, the scientific name of 2,2-bis(4-hydroxyphenyl)propane, referred to as diphenol propane.

The appearance of bisphenol A is white crystals or flake powder, insoluble in dry water, melting point at 158 159 degrees Celsius, boiling point at Celsius.

Bisphenol A can be prepared by the condensation of phenol and acetone in the presence of catalysts such as thioglycolic acid, chloroacetic acid, barium hydroxide or ion exchange resins.
