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.
3M™ Double Coated Polyester Tape 442KW features 3M™ Adhesive 830, a firm rubber adhesive system that combines adhesion, temperature performance and solvent resistance and provides a quick stick to a wide variety of materials. This adhesive has been chosen specifically for use in semiconductor CMP applications, as it laminates easily to polishing pads. It also removes cleanly from many surfaces, excellent for use with semiconductor platen.
