Global concrete foaming agents market trend 2024-2026 Different Types of Foaming Agents (4) by Newsmensmentore

The purchasing pace at the demand end of the international thermal coal market continues to slow down and the international thermal coal price continues to decline. Prices for thermal coal at major international ports continued to fall last week as buyers in Europe slowed in recent days for April, coupled with weaker-than-expected import demand from End users in China. According to China Coal Market net monitoring:  Australia Newcastle port thermal coal price index was 253 USD/ton, compared with 309.02 USD/ton, down 56.02 USD/ton, down 18.13%. South Africa's Port Richards thermal coal price Index was $264.5 / mt, down the US $62.72 / mt or 19.17% from US $327.22 / mt. The European ARA Tri-port thermal coal price Index was $281.8 / ton. Does the price of thermal coal in major international ports continue to decline to affect the price of the concrete foaming agents? 

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, we talked about the chemical foaming agents of OBSH and DPT. In this article, ADC foaming agents will be talked about.

 

3.    ADC Foaming Agents

With the development of the plastic industry, a single ADC foaming agent can no longer meet the demand, so the modified ADC foaming agent came into being. Abundant modification methods bring diversity, specialization, and serialization of ADC. Modification research has become the key to the development of ADC in recent years. Moreover, the ADC modification process basically has no waste, needs less investment, and has considerable economic and social benefits. 

The modification of ADC products is to optimize the gas generation, particle size, color, and thermal decomposition temperature of the foaming agent, mainly through changing certain reaction conditions or adding certain additives in the preparation process. ADC particle micro refinements; Add additives in ADC powder; Different types of foaming agents were mixed to achieve the modification effect.

 

Currently, the main types of modified products are: 

1. Particle micro refinements type

2. Low-temperature type. The decomposition temperature of ordinary ADC is generally higher than 200. Many resins with low softening points and easy aging under heat hope to have low-temperature decomposition products. At present, the development of low-temperature ADC is one of the main research topics in its modification field. It mainly selects one or more activators and combines them with ADC in a certain proportion. The activators can choose metal compounds such as chromium, zinc, lead, urea derivatives and nitroguanidine, etc. After modification, the lowest decomposition temperature of the ADC foaming agent can reach 80

3. Highly dispersed type. In order to obtain a uniform polymer with a smooth surface without holes, it is necessary to completely disperse the foaming agent proportionally in the polymer. Generally, ADC foaming agents are susceptible to static electricity and other factors, which agglomerate and affect product quality. It is very important to develop highly dispersed products. ADC foaming agents can be mixed with fine powder of some inert inorganic compounds, and highly dispersed products can be prepared by adding surfactants to ADC products. 

4. Inhibit foaming. Dicarboxylic acids and their hydrazides, phenols, amines, and triazoles can inhibit the decomposition of ADC, and the inhibition effect is better when a metal ion activator is available. For example, the addition of inhibiting foaming foaming agent materials will cause uneven patterns due to the difference in foaming effect, from which the production of foaming wallpaper and other interior decoration materials; 

5. Compound. Other additives with specific functions can be mixed with ADC, or several foaming agents can be mixed with each other, according to the principle of synergy between various additives, compound into one. Compound additives have become the mainstream of the development of the plastic additives industry. 

6. Foaming agent masterbatch. Like other synthetic material additives, master leasing has become one of the modification trends of foaming agent ADC. Mixing ADC, foaming agent, and polymer to get masterbatch, effectively solving the problems of dispersion and dust pollution.

The war in Russia and Ukraine is roiling global financial markets. Russia and Ukraine are important commodity suppliers in the world, so their conflict is bound to make a full impact on the global commodity supply. In view of this, the price of the concrete foaming agents may continue to rise in the future.
