Details
Highlights
- 5 mil (0.13 mm) total thickness spacer is ideal for withstanding repeated stress of switch actuation
- 1 mil (0.03 mm) polyester film carrier provides strength and stability
- 2 mil (0.05 mm) acrylic adhesive on each side delivers excellent shear strength, resists slippage and edge lifting
- 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 7945MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 1 mil (0.03 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.
3M™ High Performance Acrylic Adhesive 200MP is a popular choice, and industry standard, for graphic attachment and general industrial joining applications. This adhesive 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 short-term heat resistance, excellent solvent resistance, and excellent shear strength to resist slippage and edge lifting. High shear strength withstands repeat stresses of switch actuation. Designed to separate switch circuitry until actuation.
Suggested applications
- Ideal for circuit separation in switches until actuation
- Used for steel rule die-cutting
- Ideal for circuit separation in switches until actuation
- Appliance, electronics, industrial controls equipment, medical equipment, medical devices, automotive, tam machines, gas pumps
