Product description

  • tesa® 51865 - Team 4965 Differential is a transparent, double-sided industrial mounting tape consisting of a PET backing and a tackified acrylic adhesive. The asymmetrical double-sided tape is the differential version of tesa® 4965 Original and its adhesive is based on a patented and protected product technology. The liner covered side of tesa® 51865 - Team 4965 Differential has a high coating weight for maximum flexibility and versatility on multiple surface demands. The open side has a reduced coating weight which delivers a secure bond to flat profiles laminated under controlled conditions. tesa® 51865 - Team 4965 Differential is able to withstand numerous environmental factors such as humidity, UV-light and temperatures of up to 200°C for limited periods of time. The tackified acrylic adhesive makes for an excellent hold on various surfaces, high tack, and good shear strength.
Several products are equipped with this unique and high performing product design and together these products make up Team 4965. This double-sided film tape assortment helps to easily select the most efficient tape based on customer demands, products, and processes. Explore the benefits of the full tesa® 4965 assortment here:
