Abstract:
Antistatic agents and their use in processing textiles or formed plastic substrates. The antistatic agent comprises a compound having a fluorocarbon moiety and an ethoxylated quaternary ammonium moiety. The antistatic composition increases the electrolytic conductivity of treated textile or plastic materials, thereby increasing the rate of electrostatic charge dissipation thereof. The antistatic agents remain effective after exposure of the treated substrate to an aqueous environment.

THE COMPOUND HAS A MOLECULAR WEIGHT BETWEEN ABOUT 4,000 AND 135,000 AND THE ETHYLENE OXIDE MOIETY MAKES UP 10 TO 90% OF THE MOLECULAR WEIGHT OF THE COMPOUND.
Abstract:
A method of forming an antistatic plastic includes providing a mixture containing 10 parts by weight of crystalline silicon particles, 1 to 30 parts by weight of an encapsulant, and 0.5 to 25 parts by weight of a backsheet material. The mixture is compounded to form an antistatic plastic, wherein the encapsulant is different from the backsheet material.
