Is acetal copolymer a dangerous good? Request help to provide a basis.

Acetal copolymer is a hazardous chemical, which can be checked in detail in the "Catalogue of Hazardous Chemicals".

Article 269 in the 2015 version, which clearly states paraformaldehyde.

That is, acetal copolymer is a hazardous chemical.

First of all, acetal copolymer is a dangerous good, you can check the MSDS provided by the factory, or search on the Internet yourself, you can see it. Then you look at item 14 of his MSDS and you will see that he belongs to several categories of dangerous goods.

Specifically, copolymer formaldehyde (paraformaldehyde) is another name: polymeric formaldehyde, CAS number: 30525-89-4, UN2213, dangerous goods grade flammable solid), packaging category:

iii. Import and export need to be operated in accordance with dangerous goods.

If you have any other questions, please feel free to contact us.

If you look at this name, yes, because formaldehyde is originally a dangerous good, and if it is copolymerized, according to the knowledge of chemistry, it is also a dangerous good, I hope mine will help you.

The hazard label for paraformaldehyde is 8;

Dangerous goods have a hazmat class code table, where 8 is corrosive.

Because paraformaldehyde belongs to Class 8 dangerous goods, it is a dangerous good.

Generally, formaldehyde is toxic, toxic substances belong to 6 categories of dangerous goods, and details can be found in the "Catalogue of Hazardous Chemicals".

These two items are not dangerous goods, if we use them in a safe situation in accordance with the instructions, in fact, there is not much problem, we must pay attention to the use of each step and the amount of use.

Acetal copolymer is a class 4 dangerous goods un is 2213, and some customers have exported it.

There are paraformaldehyde and paraformaldehyde; Acetaldehyde copolymer is not a general term; If it is a mixture, then the components should be tested; to be defined. Because this product is not included in the hazardous chemicals catalog.

When it comes to paraformaldehyde, you may quickly think of "formaldehyde". That's right, as a polymer of formaldehyde, paraformaldehyde is a solid powder that is convenient for storage and transportation, and is widely used in industry, and is also a common dangerous goods in import and export links.

Formaldehyde aqueous solutions polymerize during long-term storage or concentration operations to form paraformaldehyde. At present, the industry basically uses catalytic polymerization to prepare paraformaldehyde. The rapid polymerization of formaldehyde is promoted by the addition of catalysts such as alkali (NaOH), acid (H2SO4), alkaline earth metals and their oxides (MGO), etc., which also leads to the introduction of catalyst impurities into the resulting paraformaldehyde end product.

Paraformaldehyde is widely used, and is used in a large number of pesticides, coatings, resin synthetic raw materials and papermaking additives, among which paraformaldehyde synthetic resin, that is, solid formaldehyde is used to replace the traditional liquid formaldehyde, which can avoid the danger of the synthesis process of liquid formaldehyde as raw materials, and at the same time, greatly reduces the generation of wastewater, and makes the survival process more safe and environmentally friendly while ensuring the high stability of the product.

Paraformaldehyde is a kind of dangerous goods listed in the United Nations TDG regulation "List of Dangerous Goods" (referred to as DGL) in the transportation link

UN number 2213 is classified as a Class 1 flammable solid.

Correct shipping English name: paraformaldehyde

Correct transportation Chinese name: Semi-formaldehyde.

Is co-methanol a dangerous good? Ask for help to provide evidence, of course it is a dangerous good, formaldehyde is a hazardous substance, it is so it is a dangerous good.

I think this kind of normal situation should also belong to one of the dangerous goods, so we still need to be cautious at this time, it will be better.

It should be dangerous goods, you can go to the Internet to check his specific meaning, what chemical reaction his ingredients will cause.

Chemical products are still dangerous, and there are many detailed descriptions of the severity of these ---.

Summary. Toxic and harmful hazardous chemicals include: formaldehyde, formaldehyde chloride, vinyl chloride, chlorine, chloromethane, chloropropane, acetaldehyde, ammonia, chlorofluorothane, propylene, ethylene, chloroacetaldehyde, etc.

Toxic and harmful hazardous chemicals include: formaldehyde, formaldehyde chloride, vinyl chloride, dust closed chlorine, chloromethane pyrochlorohydrin, chloropropane, acetaldehyde, ammonia, chloroflurane, propylene, ethylene, chloroacetaldehyde, etc.

Generally speaking, the hazardous chemicals used in polyoxymethylene plants include: formaldehyde, formaldehyde ethylene, vinyl chloride, vinyl chloride, chloroethylene, chlorofluorocalyptine, acrylic emulsion, chloropropylene, acrylic resin, polyurethane resin, solvent oil, chloroprene, chloropreneethylene, silicone grease, vinyl chloride, etc.

The World Health Organization (WHO) issued Bulletin No. 153 announcing that formaldehyde can cause cancer in humans as confirmed by the International Agency for Research on Cancer.

Long-term repeated exposure to low concentrations of benzene can cause chronic poisoning, mainly due to the damage of Suitan to the nervous system and hematopoietic system, manifested as headache, dizziness, insomnia, continuous decrease in white blood cells, thrombocytopenia, and can lead to various types of leukemia. The International Agency for Research on Cancer has confirmed benzene as a human carcinogen.

Formaldehyde and benzene are the main substances in decoration pollution, so decoration pollution causes or increases the probability of childhood leukemia to varying degrees. In addition, the decoration pollution harmful gases are also easy to cause pregnant women to have a higher chance of miscarriage and malformed babies.

For the sake of good health, we should take elimination measures as soon as possible, and recommend to you a product that we commonly use with good results, ZXL-002 photocatalyst, which can effectively remove harmful gases such as formaldehyde, and sterilize and disinfect, with a comprehensive long-lasting effect.
