Antistatic masterbatch is obtained by high-speed mixing, extrusion molding, and pelletizing of carrier and antistatic system. It is used to reduce the surface resistance of materials and prevent the adverse effects of static electricity on various industrial sectors and humans. It is also called antistatic masterbatch. Polymers are insulators under normal circumstances, and usually have a surface resistance of more than 10^12Ω. Antistatic packaging materials require a surface resistance of 10^7-10^11Ω. So what are the application ranges of antistatic masterbatch?
Antistatic masterbatch is suitable for blow molding, injection molding, extrusion and other molding processing methods; it can be evenly dispersed inside the plastic product, and the active factors and nanomaterials in the masterbatch migrate to the surface of the plastic product to reduce its surface resistivity and disperse the surface charge density, thereby achieving an antistatic effect; and the following undesirable phenomena of plastic products can be improved:
1. From the perspective of aesthetics and hygiene, for most plastic products, dust adsorption must be prevented during storage and use to avoid affecting the appearance and performance of the product.
2. When processing plastic products with a large area such as film and fiber, the force generated by static charge greatly interferes with the processing process, which will hinder the normal winding of film and fiber, and the printability of the product is also interfered by static charge.
3. High static charge leads to discharge, which will damage the performance of the product: such as the packaging and disassembly of electronic chips, and the normal operation of high-precision instruments such as electronic communications and medical devices.
4. Spark discharge can cause serious accidents: for example, in flammable and explosive places, charge discharge can cause fire or explosion.
