Copaco-125  is a very robust electrical insulation presspaper with extremely high tensile, elongation, tear, burst and dielectric properties. It is normally supplied in with a high density, very smooth “Glazed Roll” finish .The product is well suited to be punched, formed or creased. 

While having all the mechanical properties of Copaco the Copaco-125 Super Stretch insulating papers are manufactured under an extensible paper process that provides this material with twice the stretch of ordinary electrical insulating papers. This unusual elongation permits Copaco-125 to stretch and absorb energy when subjected to extreme stress. The high tear resistance will virtually eliminate torn or split insulators when used under standard practices. The extensible paper process is entirely mechanical and in no way affects the high purity or chemical properties.

COPACO-125 is available from .003″ to .125″ in rolls, sheets, or coils slit to your specifications.
