Global foaming agent market trend 2025-2028 Different Types of Foaming Agents (1) by Newsduotonic

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many foaming agent.

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.

Recently, the first press conference of the Boao Forum For Asia Annual Conference 2022 was held. Two flagship reports were released at the conference: "Asia's Economic Prospects and Integration Process 2022" and "Sustainable Asia and the World 2022-Green Transformation in Action in Asia".

The flagship report points out that the global economy will recover in 2021, and the pace of economic integration in the Asia-Pacific has not stopped even in the face of the impact of COVID-19. The Asia-Pacific region has provided new impetus for the world's economic recovery and institutional building.  

The report gives an outlook on the Asian economy, noting that a number of factors will affect Asian economic growth. For example, mutated strains such as Delta and Omicron have become more transmissible, and many economies are experiencing epidemic peaks again. The Ukraine crisis has triggered geopolitical changes in Asia and Europe, leading to higher commodity prices, which may affect the global energy supply and energy transformation.

The report pointed out that the Asian economy will still be in the process of recovery in 2022, but the growth rate may moderate. According to the report, Asia's economic growth in 2022 is likely to be lower than the current IMF forecast, which is projected at 4.8%.

Affected by several factors, the supply of the foaming agent is erratic and thus its prices are expected to go higher in the future.
