Product information

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.

Main applications

  • tesa® 51970 is a highly adhesive mounting tape for various industrial uses
  • The optimal balance of adhesion properties makes tesa® 51970 ideal for various applications in the blinds industry, such as roller blind core starting and laminating hard to adhere fabrics and meshes
  • The tape can be used for mounting plastic and wooden trims
  • Suitable for mounting decorative materials and displays
  • tesa® 51970 is used for mounting transparent signs and scales
