Premium 3.5 mil double coated, double linered membrane switch spacer tape with clear polyester carrier and 3M 200MP acrylic adhesive for industrial switch applications
3M™ Double Coated Double Linered Tape 7953MPD is a premium membrane switch spacer product engineered for demanding industrial applications. This 3.5 mil thick double linered, double coated tape features a clear polyester film carrier with 3M™ 200MP High Performance Acrylic Adhesive on both sides, specifically designed to aid in the separation of switch circuitry until actuation. The product combines exceptional adhesion properties with superior durability, making it ideal for applications requiring repeated stress cycles and precise switch actuation performance.
This innovative membrane switch solution delivers outstanding performance through its high shear strength formulation that withstands repeated stresses of switch actuation while resisting slippage and edge lifting. The clear polyester carrier brightens overlays and key pads, effectively eliminating the need for additional floodcoat applications. With dual polycoated kraft paper liners on both sides, this product provides moisture stability for easy, layflat processing and ensures clean application with excellent die-cuttability.
The 6 inch wide by 540 yard roll format provides substantial material for high-volume manufacturing operations. Engineered with 3M™ 200MP High Performance Acrylic Adhesive, this tape offers outstanding adhesion to metal and high surface energy (HSE) plastics, with proven performance through difficult environmental conditions and millions of actuations. The product is specifically formulated for industrial and occupational use, meeting stringent requirements for aerospace, automotive, electronics, medical device, and general industrial applications.
