Variants
The spacer films in the 3M 200MP adhesive series are designed in particular for the manufacture of membrane keypads and front panels, are shear-resistant (even with narrow webs), permanently elastic and highly resistant to ageing. The spacer films, which are temperature-resistant from -40°C and up to +120°C (up to +150°C for short periods), are chemically compatible with various conductive pastes and special colours and offer a high level of transparency. The spacer films do not bleed at the punched edges.
