3M™ metalized film tape 8437 is comprised of a relatively thin polyester backing with a metalized coating on both side of the film providing a mirror-like finish with low emissivity and a versatile, long lasting acrylic adhesive. A silicone coated release liner helps with ease of handling and allows for large area applications and die cutting custom shapes. Our 3M™ metalized film tape 8437 is generally used for splicing and web applications. The backing is a thin, high tensile strength polyester with a metalized coating on both sides. The metalized surface gives many of the advantages of metal tape without the associated weight. This backing provides some conductivity and maintains a bright, mirror-like appearance. It also meets low-caliper requirements to ensure it won't interfere with most machinery. The tape can withstand a wide temperature range from -60 deg F/-50 deg C to 300 deg F/150 deg C. A pressure sensitive acrylic adhesive grabs on contact and holds securely. 3M™ metalized film tape 8437 is mounted on a liner to allow for large area applications and die-cutting.
