3M™ Membrane Switch Spacer Double Linered 9045MP features 3M™ High Performance Acrylic Adhesive 200MP, formulated for excellent shear strength, on a 1 mil PET film carrier. Adhesive withstands repeated switch actuation and forms clean edges for precise slitting and die-cutting. Heavy 94# PCK paper liners resist humidity, curling, tunneling and buckling and add stability for improved processing.
A Top Performer Before, During and After Application
Featuring 3M™ High Performance Acrylic Adhesive 200MP, our 3M™ Membrane Switch Spacer Double Linered 9045MP is ideal for the stresses of switch actuation over long periods. The adhesive on this double-sided spacer is formulated for excellent shear strength – forming 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 mils to each side of a 1 mil polyester film carrier which adds structural strength.
Double 94# polycoated kraft (PCK) paper liners are heavier than standard liners for improved handling and lay-flat properties. They are designed to cover adhesive consistently for full bonding performance after application. Durable 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.
Resilient and Ready
3M™ Membrane Switch Spacer Double Linered 9045MP is constructed with 2 mil high performance acrylic adhesive that is coated on each side of a 1 mil polyester film carrier. This membrane switch spacer comes double-linered with a heavy 94# moisture-resistant PCK paper. Designed to separate switch circuitry until actuation, our 3M™ Membrane Switch Spacer Double Linered 9045MP provides excellent high temperature resistance (up to 400°F/204°C short-term heat resistance), as well as chemical and UV resistance.
About Our High Performance Acrylic Adhesive 200MP
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.
The Right Choice for a Range of Applications
With low cost, long life, outstanding environmental performance and eye-catching graphics, membrane switches are found in more and more applications. 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.
Better Science for Better Adhesives from 3M
Since 1925 when one of our lab assistants invented masking tape, 3M has been applying science to life –developing adhesive products and technologies that help entire industries and individual businesses worldwide. The work that began with a single 3M engineer now spans decades and generations. And all of it goes into each of our industrial labeling and adhesive products like 3M™ Membrane Switch Spacer Double Linered 9045MP, to help businesses like yours operate faster, better and more efficiently.
