The use of azodicarbonamide as blowing agent

In the production of foams as blowing agent azodicarbonamide used. When thermal decomposition of the allocated nitrogen, carbon dioxide, carbon monoxide, ammonia. In the polymer they form a foam layer in the form of bubbles.

The product finds application in the manufacture of plastics, artificial leather and other industries. It can be cleaned and modified. Special additives in its composition are called activators. They reduce the decomposition temperature.

The chemical blowing agent used in the production of vinyl (PVC). At high temperatures it promotes the formation of bubbles. Vinyl foam is springy and does not slip on smooth surfaces. It allows to use it in the manufacture of rugs and carpet backings.

The expander has the form of a powder from light yellow to orange. All major brands in the decomposition give about 230 ml/g of gas. Blowing agent approved for use in the production of products in contact with food products, according to American and European legislation.

During the reaction forms a gas (35%), solid residue (40%) and sublimate (25%). The gas consists of 65% nitrogen, it is 32% carbon monoxide and 3% other gases. Ammonia is formed at high temperatures.

Company GOROS21.RU implements high quality azodicarbonamide brand as-5. The product is available in our warehouse in Moscow region. We supply it under a direct contract from the manufacturer.

Properties, the use of potassium iodide

Potassium iodide — a compound iodomethane acid and potassium. Used as the main active ingredient in the manufacture of medicines (for both people and animals). Potassium iodide can also be used in food industry for production of iodized products (salt, etc.)

Physical and chemical properties of potassium iodide

The substance is a white-gray crystals or fine powder of the same color. Soluble in water, alcohol and glycerine, does not change color when coming into reaction with oxidising agents (ozone, chlorine, etc.). Due to this feature can be used in analytical chemistry.


Potassium iodide is primarily used in the pharmaceutical industry. It is the main active ingredient of drugs for the treatment and prevention of:

Iodine-deficiency States, including endemic goiter, cretinism, and others.

Endocrine diseases, mainly thyroid abnormalities: Hypo - and hyperthyroidism, thyrotoxic crisis, and others.

Radiation sickness.

Diseases of the upper respiratory tract: bronchial asthma, actinomycosis, inflammatory processes of different origin.

In ophthalmology, limited: cataract, hemorrhage in the iris of the eye, fungal invasion in the conjunctiva and cornea.

Of sialadenitis (inflammation of salivary glands) and xerostomia.

Potassium iodide is rapidly absorbed and excreted from the body. Preparations on its basis (in the absence of inclusion in the composition of other chemically active substances) used for the treatment of pregnant women and infants, children and adolescents, elderly patients.

Pharmacokinetics and pharmacodynamics

Potassium iodide has diverse and multidirectional action. In the first place it compensates the deficiency of iodine and at a certain level, regulates the production of thyroid hormones. Depending on the dosage of potassium iodide can restore its operation to normal (when filling the lack of iodine in several other cases) or, conversely, block (with an excess of iodine, the thyroid gland slows down the production of hormones).

In addition, potassium iodide stimulates the cough reflex and is mucolitics — due to these effects it can be used for the treatment of respiratory diseases. Finally, the substance also has antifungal activity.

The ingestion of potassium iodide for 1-2 hours absorbed by the mucous membrane of the small intestine and is evenly distributed into the intracellular spaces. When exceeding physiological doses of the substance accumulates mainly in the thyroid gland, in smaller amounts in the salivary and mammary glands. Potassium iodide is excreted by the kidneys. Statistically reliable data on the dangers of substances for the kidneys is not.


We have provided potassium iodide is made by G. Amphray Laboratories (India). GOROS21.RU is their official and exclusive dealer in Russia and thus guarantee the best prices.
