AC blowing foaming agent is a yellow to orange crystalline powder. As a chemical blowing agent, it can be used in many industries, especially plastics and rubber.
According to the way the foaming agent produces bubbles in the foaming process, the foaming agent can be divided into two categories: physical foaming agent and chemical foaming agent, in general, the physical foaming agent is the use of its change in the physical state within a certain temperature range to produce pores, and the chemical foaming agent is one or more gases produced by chemical changes in the foaming process, which can make the polymer foaming.
The
AC blowing agent is commonly used as a chemical blowing agent, which has a wider range of applications.
So what is the difference between it and the traditional physical blowing agent?
(1) Physical blowing agent (such as nitrogen, carbon dioxide) requires special high-pressure equipment for injection, which is complex and costly, while AC blowing agent can be directly disintegrated into gas under heating conditions, simple operation and low equipment requirements.
(2) The so-called chemical blowing agent refers to those substances that produce gas and then foam through chemical changes in the foaming process. There are two ways to produce the general gas: one is the by-product of polymer chain expansion or crosslinking; the other is by adding a chemical blowing agent to produce foaming gas.
(3) In addition, blowing agents can also be divided into two categories according to their chemical properties: organic blowing agents and inorganic blowing agents. Among them, the common organic blowing agents mainly include azo (AC, AIBN, etc.), hydrazine (BSH, TSH, OBSH, etc.), amino urea (TSSC), tetrazoles (5-PT, etc.), nitroso compounds (DNPT, etc.) and so on.
What are the advantages of using organic blowing agents?
1. Narrow decomposition temperature range, easy to control.
2. Good dispersion in polymer.
3. The N2 gas generated is not easy to escape from the foam, so the foaming rate is high.
4. Small particles, small foam pores.
Therefore, the
AC blowing agent can be favored by manufacturers and manufacturers, not only depends on the AC is more favorable than other chemical blowing agents, but also because the AC blowing agent itself has many advantages.
(1) Efficient gas release
High capacity: ADC blowing agent can produce a large amount of gas during decomposition, which allows workers to achieve good foaming results even when using small amounts.
Uniform foaming: In the decomposition process, uniform gas release can help the material form a regular bubble structure, thereby improving product quality and thus improving the productivity of the assembly line. As a professional manufacturer of blowing agents, we help industry customers and provide high quality blowing agents to distributors and manufacturers.
(2) Thermal stability and processing adaptability
Strong thermal stability: Blowing agent AC has good thermal stability in the temperature range of 200-220°C during the decomposition process. It will not be decomposed in advance to ensure security during use.
Wide temperature range: AC blowing agents can be adapted to many processing temperatures of plastics and rubber, which promotes their use in mass production processes.
(3) Excellent physical and mechanical properties
Uniform bubble structure: Through symmetrical gas release, AC blowing agent can form a stable and uniform structure inside the material, which greatly improves the mechanical properties and quality of the product.
Improved material properties: Product materials through the use of AC blowing agents generally have better elasticity, thermal insulation and vibration damping properties.
(4) Compatibility
A variety of polymers: Blowing agent AC can be used in different polymer materials, such as PVC, EVA, PE, PP, rubber, etc. Therefore, AC blowing agent can be applied in different fields. In addition, in the process of plastic processing, blowing agent AC can also be applied to a variety of processing technologies, including plastic injection molding, plastic extrusion and plastic blow molding.
(5) Economic and environmental protection
The high gas yield of AC blowing agent means that less blowing agent is required in production, which can effectively reduce the cost of use.
Environmentally friendly: Compared with other chemical blowing agents, AC blowing agents leave less residue after use and are easier to handle.
(6) Safety and controllability
Temperature control: The decomposition temperature of AC blowing agent is between 200-220°C, easy to control. Helps ensure the safety of the foaming process.
Less toxic: The gas produced by AC blowing agent is mainly nitrogen, carbon dioxide and a small amount of carbon monoxide, which produces less toxic.
To sum up,
AC blowing agents are an essential component in many industries due to their high purity and wide-ranging applications. If you need foaming agents in your industry,please don't hesitate to contact us at any time.
