3M™ Double Coated Polyester Tape 442KW is a double sided tape featuring a rubber based adhesive, ideal for laminated bonding with semiconductor CMP polishing pads and clean removal from platens. A thin polyester (PET) film carrier helps the adhesive bond firmly to both platen and pad. A polycoated paper release liner provides excellent dimensional stability.

Adhesive is applied to film carrier on both sides for effective lamination to pads and clean removal from platens. Also applicable for polishing pad attachment to platens in HDD and glass manufacturing. Attaches polishing pads to platens for chemical mechanical planarization (CMP) in semiconductor manufacturing. Polyester carrier film helps improve handling for uniform application. Release liner adds dimensional stability for fast and efficient conversion. Rubber based adhesive provides fast, reliable bonding strength and removes cleanly
