tesa® 51970

Transparent double-sided filmic tape

Product description

tesa® 51970 is a transparent, double sided tape consisting of a PP film backing and a tackified adhesive. tesa® 51970 features an excellent combination of high tack and adhesive strength. It bonds securely even on critical materials such as PP, PE and rough surfaces. The mounting tape's good temperature resistance, as well as UV and humidity resistance make it ideal for outdoor use. The tape can withstand chemicals and softeners. tesa® 51970 is frequently used for industrial mounting applications, for instance, the mounting of plastic or decorative materials.
