3M 431 aluminum tape
Description
[3M Industrial Adhesives and Tapes Division] A 2ml wide nominal shiny silver-color tape adhesive tape with dead soft Aluminum foil backing and highly engineered pressure sensitive, transparent Acrylic adhesive. Aluminum tape is reflective, UV resistant and thermally conductive. The flexible metal allows the tape to conform to curves and uneven surfaces. Its thermally conductivity helps dissipate heat and improves heating and cooling efficiency to protect temperature sensitive materials. The acrylic adhesive that adheres well in a wide range of temperatures and humidities. Additionally, the its ability to reflect heat and light protects surfaces and enhances lighting efficiency.
