Product description
tesa® 51865 Next Gen – Team 4965 Differential is a transparent, double-sided industrial mounting tape, produced with a biomass balanced adhesive and a 90% PCR PET backing which leads to a reduction in CO₂ emissions of -37%1 compared to tesa® 51865. The asymmetrical double-sided tape is the differential version of tesa® 4965 Original Next Gen and its adhesive is based on a patented and protected product technology. The liner-covered side of tesa® 51865 Next Gen –Team 4965 Differential has a high coating weight for maximum flexibility and versatility for multiple surface demands. The open side has a reduced coating weight that delivers a secure bond to flat profiles laminated under controlled conditions. tesa® 51865 Next Gen – 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 biomass balanced tackified acrylic adhesive offers excellent hold on various surfaces, high tack, and good shear strength.
Several products are equipped with this unique and high-performing product design. 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:
