D-Encapsulant Cable Filler

Vertellus D-Encapsulant Cable Filler

D-Encapsulant Cable Filler

describe
Vertellus D-Encapsulant is a two-component elastic polyurethane compound for fiber optic and copper cable fill applications. It has low viscosity and extended pot life to form an effective water seal, as well as excellent flexibility, electrical properties and long-term stability. This product is especially suitable for environmental protection of electrical equipment.
