Membrane Switch Spacer

Model # 7979

A 9.0 mil. polyester backed tape with #600 “isotac” acrylic adhesive primarily used for membrane switches and keyboards. Isotac adhesive for switches must withstand high temperatures of harsh chemical environments. The 2.0 mils. of adhesive on each side of backing ensures secure bond that prevents channeling or buckling. 7979 tape has high internal strength to withstand repeated stresses from switch actuation. Use steel rule die cutting and sharp, lubricated dies through processing, and a combination of metal and rubber rollers with moderate pressure is recommended.
