Tesa 50UM Strong Self-Adhesive Aluminum Tape 50?m Flame Retardant DIN 4102 UL 510A

Product Overview

Tesa 50UM Strong Self-Adhesive Aluminum Tape is designed for sealing, bonding, and repair tasks requiring high durability and environmental resistance. Used in HVAC installations, insulation work, and industrial maintenance, this tape meets stringent B2B requirements for mechanical and thermal performance. It operates reliably between -40°C and +160°C, maintains chemical stability, and fulfills fire resistance standards DIN 4102 (class B1) and UL 510A.

A transparent acrylic adhesive layer sets this product apart, ensuring strong adhesion to varied surfaces while enabling clean, efficient application and repositioning when necessary. This eliminates the risk of installation errors and improves productivity in professional and industrial environments. Especially suitable for HVAC contractors, facility maintenance teams, and commercial insulation projects demanding certified flame resistance and all-condition adhesion.
