Abstract
Authors investigated the property of water-soluble surface active agents as external antistatic agents for plastic resins. Sheets, films and monofilaments from plastic resins were dipped into aqueous solutions of surface active agents, picked up and dried at room temperature. The surface resistivity and charge generation by rubbing with Nylon were measured at 20°C and RH 65%.
Anionic and nonionic surface active agents did not exhibit good antistatic property for plastic resins, but cationic and amphoteric surface active agents, which were very substantive with plastic resins, were demonstrated as the excellent antistatic agents.
The property of external antistatic agents was diminished away by washing, long storage and rubbing with other articles.
