3M Membrane Switch Spacer 7957MP Clear, 24 in x 36 in 7 mil, 100 sheets per case

3M™ Membrane Switch Spacer 7957MP is a high-performance spacer specifically engineered for demanding switch applications. It features the renowned 3M™ High Performance Acrylic Adhesive 200MP, which provides exceptional shear strength and durability. This adhesive is applied on both sides of a 3 mil PET film carrier, ensuring robust performance in repeated switch actuation scenarios.

• High Performance Adhesive: The 3M™ High Performance Acrylic Adhesive 200MP offers outstanding shear strength, forming durable bonds with plastics and other smooth surfaces. This minimizes adhesive oozing at the edges, allowing for precise slitting and die-cutting.
• Durable PET Film Carrier: The 3 mil polyester film carrier enhances the spacer's structural strength, making it highly suitable for repeated switch actuation over long periods.
• Double PCK Paper Liners: The double 4.2 mil 58 lb. polycoated kraft (PCK) paper liners provide consistent adhesive coverage, resisting humidity, curling, tunneling, and buckling. This improves dimensional stability and facilitates efficient storage and processing.
• Enhanced Processing: The liner design allows for improved rotary die-cutting at high speeds and enhanced sheet processing, making it ideal for high-volume production environments.

Recommended Applications:

• Membrane switch spacers
• Switch mounting
• Circuit layer assembly
• Metal dome placement
• Lead protection
• Die-cut laminations

Usage and Maintenance: Ensure surfaces are clean and dry before applying the membrane switch spacer. Apply with firm pressure to achieve maximum adhesion. Store the product in a cool, dry place away from direct sunlight to maintain its properties. The high-performance adhesive and durable liners make this spacer suitable for long-term use in demanding switch applications.
