Global foaming agent market trend 2025-2029 Different Types of Foaming Agents (1) by Newsinwin-style

Since 2022, Russia-Ukraine geopolitical conflicts have intensified, and global energy prices have risen sharply, with international natural gas prices hitting historic highs. As the most important transitional energy source in the transition from fossil energy to non-fossil energy, the share of natural gas in primary energy has increased from 14.6% in 1965 to 24.7% in 2020.  The global gas price indices showed a unilateral downward trend from 2018, bottomed out in 2020, and remained low for a long time. However, since July 2020, the global gas prices have gradually fluctuated upward, and the impact of geopolitical events made the Dutch TTF gas price even hit record highs repeatedly.

An analyst of a securities company believes that the core catalyst of this round of global gas market lies in the lack of investment in upstream oil and gas resources caused by long-term low prices. Since 2020, although the epidemic has led to a decline in demand, the decline in supply has been faster, resulting in a large inventory consumption. In 2021, demand will recover faster than supply (the supply-side is less sensitive to prices, which will be reflected in investment).  

As the world's two largest gas foaming agent are also expected to change significantly.

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 this article, the physical foaming agents of carbon dioxide foaming agents and hydrochlorofluorocarbon foaming agents will be talked about.

 

Physical foaming agents

There are many kinds of physical foaming agents, such as aliphatic hydrocarbons, chlorofluorocarbons, hydrochlorofluorocarbons, carbon dioxide gas, etc. Since the 1950s, CFC-11 has been widely used as the preferred foaming agent of polyurethane. In order to protect the earth's ecological environment, the use of CFCS compounds must be banned because of their destructive effect on the ozone layer. People have been looking for and developing ideal alternative products for many years. In addition to considering the properties of the foaming agent itself, it is generally necessary to adjust and improve the raw materials such as polyether polyol, foaming agent, and catalyst to optimize the formulation system. At present, there are mainly four alternatives to foaming agent CFC11. 

 

1.    Carbon dioxide foaming agents

There are two kinds of carbon dioxide foaming agents, one is the reaction of isocyanate and water to produce carbon dioxide as foaming agents (water foaming), and the other is liquid carbon dioxide. 

Compared with CFC-11, water foaming has the advantages of zero carbon dioxide ODP (ozone loss value), is non-toxic, safe, has no recycling problems, and no need to invest in foaming equipment. The disadvantage is that the polyol component viscosity is higher in the foaming process, the foaming pressure and the foam temperature are higher, the adhesion of the foam plastic and the base material becomes worse, especially the thermal conductivity of the hard foam product is high. Due to the rapid diffusion of carbon dioxide from the bubble hole and the slow entry of air into the bubble hole, the dimensional stability of foam plastics is affected. Although it can be improved by modification, it is still inferior to the CFC-11 foam material. At present, it is mainly used for heat supply pipeline insulation, packaging foam and agricultural foam, and other fields with low requirements for insulation. Liquid carbon dioxide foaming has the same advantages and disadvantages as water foaming. It is mainly used for polyurethane soft foam at present. For hard foam, it can overcome the disadvantages of water foaming, which increases the consumption of isocyanate, foam brittle, and poor adhesion with the base material. But liquid foam to improve the foaming machine, liquid carbon dioxide storage, and transportation costs increased.

 

2.    Hydrochlorofluorocarbon foaming agents

Hydrogenated hydrochlorofluorocarbons (HCFC) foaming agents contain hydrogen in their molecules, have unstable chemical properties, and are easy to decompose, so their ODP is far less than CFC-11. Therefore, HCFC is regarded as the first generation of CFC foaming agent replacement products, which are used temporarily during the transition period and should be replaced by chlorine-free compounds as soon as possible. The European Union, the United States, and Japan banned the use of HCFC foaming agents at the end of 2004. Currently, the most developed product that can replace CFC-11 commercially is HCFC-14LB, which is soluble in polyols and isocyanates. When replacing CFC-11 with HCFC-14LB, the needed amount of foam in order to get the same level of density and similar physical properties is less than CFC-11. The defects of HCFC-141B lie in the high price of raw materials, the solubility of certain ABS and high-impact polystyrene, and its thermal conductivity is higher than that of CFC-11, so the foam density is higher to achieve the heat insulation effect. Another hydrochlorofluorocarbon product to replace CFC-11 is the 60:40 HCFC-22/HCFC-14LB mixture. This kind of mixture is the most commonly used solvent in industrial production. The production technology is developed and the price is moderate. The disadvantage is that the solubility of the HCFC-22/HCFC-141B system in general polyols is relatively low, and the processing of polyols containing HCFC-22 is relatively difficult. In addition, the ODP value of HCFC-124 is only 1/5 of that of HCFC-141B, allowing longer service life.

Since February, gold has enjoyed a smooth upward run on the back of surging US inflation and the brewing of war. While expectations of rate rises have also risen in tandem over this period, gold had been largely pre-priced and the underlying driver of tightening expectations had come from inflation continuing to rise to record highs. The risk aversion caused by the continued tension in the war also provided an important short-term support for gold. This will have a certain impact on the price of the foaming agent and the market of the foaming agent.
