Copaco
is a very robust electrical insulation product with
extremely high tensile, tear, burst and dielectric
properties. It is normally supplied with a high density,
very smooth “Glazed Roll” finish which eases the insertion
into slot cells, and provides excellent abrasion resistance.
The product is well suited to be punched, formed or creased.
Copaco electrical insulating rag papers are manufactured
from only high-grade new cotton cuttings, the stock is
extensively cleaned and specially refined to insure maximum
purity and physical strength. No sizing, clay, fillers, or
other chemical additives are used in Copaco. The absence of
impurities ensures that Copaco's aging characteristics will
meet your most exacting requirements
Copaco is available from .003" to .060" in rolls, sheets, or
coils slit to your specifications.
