Professional-grade double-coated adhesive tape with acrylic and silicone adhesives for bonding silicone materials, elastomers, and foam. Features 48-inch width, 108-yard length, 5.5 mil thickness, and operates from -40°F to 250°F with exceptional temperature and chemical resistance.
3M™ Double Coated Tape 9731 is a high-performance adhesive tape engineered for specialized bonding applications involving silicone materials, elastomers, and foam. This professional-grade tape features a unique dual-adhesive system with acrylic Adhesive 350 on the face side and silicone adhesive on the liner side, mounted on a 1 mil clear polyester film carrier. The combination of these two distinct adhesive types enables exceptional performance across demanding industrial applications where silicone substrates must be bonded to various materials.
The tape measures 48 inches in width and 108 yards in length with an overall thickness of 5.5 mil, making it ideal for large-scale industrial applications and die-cutting operations. It features double-lined construction with a 58# polycoated kraft paper (PCK) liner on one side and a 3 mil polyester film (PET) liner on the other, providing superior dimensional stability and reliable performance in automated dispensing systems. The thin, flexible polyester carrier offers excellent handling characteristics and is designed for ease of die-cutting and lamination processes.
This tape excels in gasketing applications, filter assembly, and bonding silicone foams and rubber components. The silicone adhesive on the back side bonds exceptionally well to silicone substrates, while the face-side acrylic adhesive provides very high adhesion to a wide variety of materials including metals, plastics, and composites. With a maximum operating temperature of 250°F (121°C) and minimum temperature of -40°F (-40°C), this tape delivers consistent performance across extreme temperature ranges. It offers excellent UV resistance, superior solvent resistance, and outstanding holding power, making it suitable for aerospace, automotive, electronics, medical device manufacturing, and general industrial applications.
