3M™ Membrane Switch Spacer 7956MP, Clear, 24 in x 36 in, 6 mil, 100 Sheet/Case

3M™ Membrane Switch Spacer 7956MP is an ideal solution for switch actuation over long periods. It features 3M™ High Performance Acrylic Adhesive 200MP that is formulated for excellent shear strength. This double-sided spacer forms a durable bond with plastics and other smooth surfaces with less oozing at the edges. This allows for easier slitting and die-cutting, faster part processing, and minimal waste. The adhesive is applied at 2.0 mils to each side of a 2.0 mil polyester film carrier which adds structural strength.

Double 4.2 mil 58 lb. polycoated kraft (PCK) paper lay-flat liners are designed to cover adhesive consistently for full bonding performance after application. Liners resist curling, tunneling, and buckling, increase dimensional stability, and hold up even under high humidity for efficient storage and processing. Liner design also enables improved rotary die-cutting at high speeds, as well as improved sheet processing.

3M™ Membrane Switch Spacer 7956MP is constructed with 2.0 mil high performance acrylic adhesive that is coated on each side of a 2.0 mil polyester film carrier. This membrane switch spacer comes double-linered with a 4.2 mil, 58 lb. moisture-resistant, lay-flat, PCK paper. Designed to separate switch circuitry until actuation, Membrane Switch Spacer 7956MP provides excellent temperature resistance (up to 400⁰F/204⁰C short-term heat resistance), solvents, and UV resistance.

3M™ High Performance Acrylic Adhesive 200MP is an industry standard for graphic attachment and general industrial joining applications. It features outstanding adhesion to metal, polycarbonate (PC), ABS, and polyester (PET), making it popular across many industries. 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, providing confidence that the switch will perform through difficult environmental conditions and millions of actuations.

Membrane switches are found in more and more applications due to their low cost, long life, outstanding environmental performance, and eye-catching graphics. They range from farm tractors and medical test systems to microwave ovens and fish finders. Whatever the need, 3M has a membrane switch construction suited for the job.

The 3M Industrial Adhesives and Tapes Division applies the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, 3M IATD technologies help customers like you deliver competitive products to the market faster and more efficiently.
