ET-20S consists of a copper tape coated on single side with an special ethylene copolymer color-coded green. The coating forms a strong moisture-resistant bond to the copper substrate that will not delaminate from contact with the copper. The coatings also form strong polymeric bonds to zero halogen, polyethene and chlorinated polyethylene jacketing resins during the jacket extrusion process thereby allowing fabrication ofbonded jacket or laminate sheath, cable. ET-20S lamination tape mainly use as sheath for medium and high voltage power cables, or as the combination shield/moisture barrier over a wire or tape screen.
