Recently, the Russian President hosted a meeting with oil and gas industry representatives.  He said that the refusal of some Western countries to cooperate normally with Russia and deny some Russian energy resources has hit millions of European people deeply and caused an energy crisis. These "unfriendly countries" are experiencing severe inflation, and Russia is also facing the three major challenges of increasing domestic consumption of energy concrete foaming agent are still very uncertain.

Introduction to Foaming Agents

The foaming agent is a kind of material that makes the object matter into pores. It can be divided into chemical foaming agents, physical foaming agents, and surface-active agents.  The chemical foaming agent is a compound which can release gas such as carbon dioxide and nitrogen and form fine pores in polymer composition after decomposition by heating.  The physical foaming agent is the change of the physical form of a certain kind of material through the fine pores of foam, namely through the expansion of compressed gas, liquid volatilization, or solid dissolution and the formation of the compound.

In the last article, the physical foaming agents of hydrocarbon foaming agents and hydrofluorane (HFC) foaming agents have been mentioned. In this article, the chemical foaming agents of OBSH and DPT will be talked about.

 

Chemical Foaming Agents

There are many kinds of substances used as chemical foaming agents. According to the chemical structure, there are mainly N-nitrite compounds, such as N, N-nitroso pentamethylenetetramine (DPT), N, N-dimethyl-N, N-dimethyl-p-benzarbonamide (NTA), etc.  Azo compounds, such as azodicarbonamide (ADC), azodiisobutyronitrile, isopropyl azodicarbonate, diethyl azodicarbonate, diazo-aminobenzene, barium azodicarbonate, etc.  Hydrazide compounds, such as 4, 4-disulfonyl hydrazide diphenyl ether (OBSH), p-benzene sulfonyl hydrazide, 3, 3-disulfonyl hydrazide diphenyl sulfone, 4, 4-diphenyl sulfonyl hydrazide, 1, 3-benzene sulfonyl hydrazide, 1, 4-benzene sulfonyl hydrazide, etc.  The main varieties used are foaming agents ADC, DPT, DBSH, and so on. 

 

1.    Foaming Agents OBSH 

OBSH foaming agent with the chemical name 4, 4' -disulfonyl hydrazine diphenyl ether, is a low-temperature foaming agent commonly used in the plastic and rubber industry. It is mainly obtained from the reaction of sulfonated diphenyl ether with hydrazine hydrate. It was first developed and used in Japan, widely used in the field of UHF wire and cable. The advantages of OBSH foaming agents are: low decomposition temperature, no need to add decomposition additives, suitable for a variety of synthetic materials; Very low toxicity, suitable for contact with food packaging materials; Good electrical insulation performance; Vulcanizing agent and foaming agent dual role; The bubbles are fine and uniform. 

 

2. Foaming Agents DPT 

The chemical name is N, N'- two nitro five methyl tetramine. It is mainly used for the rubber foaming agent, has great decomposition heat, is often added with urea, urea derivatives, and melamine to prevent irritating smell generation, basically not used for plastic foaming.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the concrete foaming agent will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of concrete foaming agent.
