In February 2026, the article "Antistatic Properties of Plastics" was released, systematically analyzing the core points of plastic antistatic technology. Plastics are divided into three categories based on charge mobility: insulating, antistatic, and conductive. Insulating plastics have a surface resistance >10¹²Ω and no free-moving charges; antistatic plastics have a surface resistance of 10⁶-10⁹Ω and require antistatic agents or conductive fillers to build charge leakage channels; conductive plastics have a surface resistance of 10⁴-10⁶Ω and rely on continuous conductive paths for current flow. Antistatic technology is divided into short-term and long-term. Short-term technology relies on migratory antistatic agents, which need to migrate to the surface to absorb water and form a conductive layer, easily failing due to wiping and greatly affected by humidity. Long-term technology uses permanent antistatic agents or fillers such as carbon black and carbon fiber to form a stable ionic conductive network, not affected by environmental humidity. In addition, resin polarity and molding temperature affect the selection of antistatic agents. For example, strongly polar materials like PA and PBT are suitable for ionic antistatic agents, while non-polar materials like PP and PE use non-ionic ones, with relevant properties tested according to ASTM D257 standard.
