tesa® 51966

200µm double sided transparent PET film tape with 90% PCR PET content in backing.

Product Description:

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 the 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 5% post-consumer recycled content, consisting of 90% recycled PET backing. The tape core is considered packaging material and is 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.
