Premium double-sided polyester tape for semiconductor CMP applications with rubber-based adhesive, clean removal, and dimensional stability for polishing pad attachment.
3M™ Double Coated Polyester Tape 442KW is a premium double-sided adhesive tape specifically engineered for semiconductor chemical mechanical planarization (CMP) applications. This industrial-grade tape features a rubber-based adhesive system (3M™ Adhesive 830) applied to both sides of a thin polyester (PET) film carrier, providing exceptional bonding strength while ensuring clean removal from platens. The tape measures 32 inches in width and comes in a 60-yard roll with a polycoated paper release liner that provides excellent dimensional stability for precise conversion and application.
The 442KW tape is specifically formulated for attaching polishing pads to platens in semiconductor manufacturing processes, offering fast and reliable bonding with superior adhesion characteristics. Its natural rubber adhesive combines exceptional adhesion, temperature performance, and solvent resistance, making it ideal for laminated bonding applications. The polyester carrier film improves handling capabilities and ensures uniform application across the platen surface, while the release liner maintains dimensional stability for consistent performance throughout the conversion process.
Beyond semiconductor CMP applications, this versatile tape is also applicable for polishing pad attachment in HDD (Hard Disk Drive) and glass manufacturing processes. With a shelf life of 18 months and indoor operation capabilities between 10°C to 38°C (50°F to 100°F), the 442KW tape delivers consistent performance in controlled manufacturing environments. The tape's clean removal characteristics make it particularly valuable for applications requiring residue-free adhesion, ensuring platens remain in optimal condition for continued use.
