Tesa 50UM Strong Self-Adhesive Aluminum Tape 50?m DIN 4102 B1 UL 510A 50m x 50mm

Product Overview

Tesa 50UM Strong self-adhesive aluminum tape is designed for demanding industrial and commercial sealing, insulation, and electrical applications. It features a transparent acrylic adhesive for strong bonding and comes in a 50 m roll with 50 mm width. The tape offers operational stability across extreme temperatures from -40°C to +160°C and is certified to DIN 4102 (class B1 fire resistance) as well as UL 510A, suitable for fire-protected installations and projects that require conformity to international standards.

A key differentiating feature is its removable protective strip made of 85 ?m white silicone paper, which facilitates quick and precise placement during installation. This reduces waste and installation errors, making it highly suited for bulk procurement in HVAC, electrical, and construction sectors where reliability and compliance are critical.
