Details
Highlights
- 9 mil (0.23mm) double-coated spacer is ideal for withstanding repeated stress of switch actuation
- 2 mil (0.05 mm) acrylic adhesive on each side delivers excellent shear strength, resists slippage and edge lifting
- 5 mil (0.13 mm) polyester film carrier provides strength and stability
- Adhesive resists oozing at edges and die-cuts for faster part processing
- Layflat polycoated kraft (PCK) liners add dimensional stability for various die-cutting operations
The 3M™ Membrane Switch Spacer 7959MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 5 mil (0.13 mm) PET film carrier. This adhesive withstands repeated switch actuation and forms neat, clean edges for precise slitting and die-cutting. Double PCK paper liners resist humidity, curling, tunneling and buckling, and add stability for improved sheet processing.
The 3M™ Membrane Switch Spacer 7959MP provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles. This tape features up to 400°F (204.4°C) short term heat resistance, excellent solvent resistance, and excellent shear strength to resist slippage and edge lifting. 3M™ High Performance Acrylic Adhesive 200MP is a popular choice, and industry standard, for graphic attachment and general industrial joining applications.
