PEL Conductive Functional Additive

PEL is an ion-conductive functional additive produced by combining a polyglycol-based polymer, primarily PAG, with salts such as lithium perchlorate.
Based on compatibility with various resins, the product line consists of several grades centered on PEL-20A and is used in a variety of polyurethane products.

Principle of PEL Ionic Conduction

Normally, perchlorate salts such as lithium perchlorate exist as solid salts with their anions and cations bound together under anhydrous conditions or in the presence of solvents, and they do not exhibit ionic conductivity when directly mixed into polymers.
In PEL, the cations of salts such as lithium perchlorate are first dissociated through solvation by ether oxygen atoms in the polyglycol (PAG).
The dissociated ions become mobile through molecular vibration of the polyglycol (PAG) and move toward the corresponding electrodes under an external electric field, generating ionic conductivity.
Unlike conductive additives based on quaternary-ammonium surfactants, this mechanism does not require moisture from the air for ionic conduction and therefore maintains conductivity even at low humidity.

Application Examples

Adding 10% to Polyurethane PEL-20Aachieves surface resistivity on the order of 10⁹Ω/□

Surface resistivity at various humidity levels after films were formed using different PEL conductive additives and an isocyanate cross-linking agent.Stable antistatic performance is maintained over a wide range of humidity conditions.

Precautions

PEL is manufactured and sold under conditions designed to maximize safety. During use and storage, keep it away from flammable environments.
Do not heat PEL above the decomposition temperature of the compounded polymer, and avoid contact with reducing substances.
Refer to the SDS before use and contact us with any questions.
