Antistatic agents

Antistatic agents (also known as antistatic additives) are substances that are added to materials, such as plastics, coatings, and textiles, in order to reduce static electricity. These agents typically provide a static dissipative coating on the surface of the material to which they are applied. The use of antistatic agents is widespread in many industries such as electronics, automotive, aerospace, and medical device manufacturing.

Antistatic agents have been used for decades to prevent short circuits and other incidents of static electricity. When static builds up on an electronic component, it can cause arcing or sparking across contacts, which can damage or destroy components. As technology becomes increasingly integrated, it is necessary to keep static electricity under control in order to maintain component reliability. Antistatic agents provide an effective way to reduce the effects of static electricity on electronics.

Antistatic agents are often applied as a liquid coating to a material, but they can also be incorporated into the material itself during the manufacturing process. Coatings made from antistatic agents can significantly reduce the build-up of static electricity on the material. This can greatly reduce the amount of arcing or sparking across component contacts, reducing component damage and failure.

Antistatic agents also help improve product reliability by protecting electronics from dust and moisture. The coating on electronic components prevents dust and other particles from being able to penetrate the component and damage it. The coating also helps protect the component from moisture, which can cause corrosion and other damage.

In addition to preventing static electricity and protecting electronic components, antistatic agents are used to reduce sliding friction on plastic components. The molecules of the coating create a barrier between the surfaces of the material, reducing the amount of friction when they come into contact with each other. This reduces wear and tear on the material, improving its lifespan and reducing the need for replacements.

Antistatic agents are often used in conjunction with other additives, such as lubricants and plasticizers. This combination can help to further improve the performance of the material, making it better suited for long-term use.

Overall, antistatic agents are an essential component of any manufacturing process, helping to improve the safety, reliability, and performance of products. In the electronics, automotive, aerospace, and medical device industries, antistatic agents are invaluable for preventing static electricity, arcing, and sparking, as well as protecting components from dust and moisture. They are also used to reduce friction and improve the lifespan of plastic parts, making them a necessary component in many manufacturing processes.

Antistatic agents refer to a type of material that reduces or prevents the generation of static electricity by adding antistatic substances to plastics, fibers, ceramics, rubbers, coatings, paper and other materials. At present, it mainly includes organic antistatic agents and inorganic antistatic agents.

Organic antistatic agents, also called organic conductive polymer antistatic agents, integrate conductive particles and polymers, or water-soluble polymers in a molecular chain, and endow electroconductivity to the material by adding them. Organic antistatic agents are generally divided into three categories according to their properties and electrification sublimation. One is that the surface resistivity is 10^8 - 10^9 Ω, the static dissipative agent; the second is 10^7 - 10^8 Ω, the static shielding agent; the third is 10^3 - 10^7 Ω, the static conducting agent.

Inorganic antistatic agents refer to antistatic agents that transfer electrons by combination chemical to reduce the electrostatic charge of materials, such as metal compounds and metal oxides. Common inorganic antistatic agents are aluminum chloride, calcium stearate, lithium stearate, aluminum stearate, zinc stearate, etc. Inorganic antistatic agents mainly used in plastics, rubber and other plastics or polymers materials with low surface resistivity.
