90% PCR PET in the backing
tesa® 51966 is a transparent double-sided industrial mounting tape with a 90% post-consumer recycled (PCR) PET backing and a highly tackified acrylic adhesive. The double-sided tape is especially designed for converter and tape specialist business and is able to withstand numerous environmental factors such as humidity, UV light and temperatures of up to 130°C for limited periods of time. The tackified acrylic adhesive provides excellent adhesion on various surfaces, very high tack, and good shear strength.
tesa® 51966 contains an average of 8% post-consumer recycled content, consisting of 90% recycled PET backing. Liner and tape core are considered packaging materials and are excluded from recycled content calculations. This is a third-party environmental claim validated against the UL Environmental Claim Validation Procedure 2809 for recycled content. The UL Environmental Claim Validation Program falls under UL’s ISO/IEC 17025 accreditation. Find more information on the UL SPOT® database
