3M™ Glass Cloth Electrical Tape 27 with Pressure-Sensitive Rubber Thermosetting Data Sheet Description October 2008 3M™ Glass Cloth Electrical Tape 27 is a 7-mil woven insulating glass cloth tape with pressure-sensitive rubber thermosetting adhesive. This tape is designed to operate in 600-volt dry applications requiring high mechanical strength and resistance to high temperatures. The glass cloth is specially treated and prepared to provide corrosion-free protection. The glass cloth will not shrink, rot or burn, has a high tensile strength and is printable. Agency Approvals, Self Certifications, MIL Specs Meets Requirements of: • UL Recognized Component listing for 302° F (150° C), Guide OANZ2, File E17385 • CSA Accepted Component 266° F,(130° C), File LR93411 RoHS Compliant 2002/95/EC” means that the product or part (“Product”) does not contain any of the substances in excess of the maximum concentration values in EU Directive 2002/95/EC, as amended by Commission Decision 2002/618/EC, unless the substance is in an application that is exempt under RoHS.
