Nonconductive Adhesive Tapes

Kapton^® Polyimide Film, 3M™ Tape 5413

This single sided tape consists of a Kapton^® polyimide film with a silicone adhesive, compatible with a wide temperature range. Kapton^® tape with silicone adhesive exhibits better adhesion to "difficult surfaces", but at the same time the high adhesive film bond greatly reduces adhesive transfer to leave a cleaner surface. This tape can be used in harsh environments and has a specified temperature use range is -75° to +260°C (-100° to +500°F). However, successful applications have been reported in the temperature range of -196° to +400°C (-321° to +752°F). Kapton^® film thickness is 1.0mil (0.03mm), total tape thickness with adhesive is 2.7 mil (0.07mm). Standard 76mm (3") plastic core.

Applications are as diverse as tape for elevated temperatures, masking for protection of contacts on printed circuit boards during wave solder or dip solder process, masking during vacuum deposition and positioning tape for cryo applications. Relatively low outgassing in vacuum.

Single Sided Kapton^® Polyimide Tape

This single sided Kapton^® tape consists of a thin Kapton^® film with a silicone adhesive on one side of the Kapton^® polyimide film. Designed to use in harsh environments and offer high performance, high reliability and durability. The Kapton tape has a high dielectric strength. Silicon adhesive protection does not leave a residue. Can withstand temperatures up to 260°C/500°F. Kapton^® film thickness is 1 mil (0.03mm), silicon adhesive is 1.5 mil (0.04mm) thick which give a total thickness of 2.5 mil (0.07mm). Length is 32.9m (36 yards). Standard 76mm (3") plastic core.

Low Static Kapton^® Polyimide Tape

This low static single sided Kapton^® tape consists of a thin Kapton^® film with a silicone adhesive with ESD additive to reduce the static charge. Designed to use in harsh environments and offer high performance, high reliability and durability. The Kapton tape has a high dielectric strength. Silicon adhesive protection does not leave a residue. Can withstand temperatures up to 260°C/500°F. Kapton^® film thickness is 1 mil (0.03mm), silicon adhesive is 1.6 mil (0.04mm) thick which give a total thickness of 2.6 mil (0.07mm). Length is 32.9m (36 yards). Standard 76mm (3") plastic core.

Double Sided Kapton^® Polyimide Tape

This double sided Kapton^® tape consists of a thin Kapton^® film with a silicone adhesive on both sides of the Kapton^® polyimide film. This product is designed to bond on silicon substrates and can be used in harsh environments with temperatures up to 260°C / 500°F. Removes cleanly from smooth surfaces with minimal chance of adhesive transfer. Kapton^® film thickness is 1.0mil (0.03mm), total tape thickness with adhesives is 4 mil (0.10mm) with 1.5 mil (0.04mm) adhesive on each side. Standard 76mm (3") plastic core.

Used for a wide variety of applications such as secure masking and/or sample in vacuum systems. Relatively low outgassing, cryo compatible.

3M™ 465 Adhesive Transfer Tape

This tape is clear and has an adhesive thickness of 2.0mil (0.002") (50µm). The double sided acrylic adhesive (high tack) also has a 4.0mil (100µm) 60lb densified kraft paper liner. The adhesive film on the paper liner transfers to most surfaces on contact. Remove the liner and the adhesive remains in place. Used for mounting or attaching. 76mm (3") core. Medium adhesive strength on both sides: 27.7g/mm (25oz/in). Available as 1/2" x 60 yards and 3/4" x 36 yards in length.

3M™ Weather Resistant Film Tape, 838

long term weather resistant and protecting applications

This single sided tape can be used for many long-term weather resistant and protecting requirements. It is a white Tedlar^® PVD with acrylic adhesive.

• Good aging properties because it contains no plasticizers.
• It remains tough and flexible over a broad temperature range.
• The properties of Tedlar^® film include excellent resistance to weathering, outstanding mechanical properties and inertness toward a wide variety of chemicals, solvents, and staining agents.
• Tedlar^® film tape is strong, flexible, and fatigue resistant.
• Can be certified to meet Mil Spec MIL-T-22085, Amendment 3, Type IV.

Temperature use range: -100° to 225°F (-73° to 107°C)
Further typical physical properties are listed on 3M™ Technical Sheet.

3M™ Silver Polyester Tape, Nonconductive, 850

Single sided silver polyester tape is used for making ultramicrotome boats, and for other applications. The tape is 1.0mil (0.025mm) thick. Silver appearance due to aluminum coating on the polyester film. Acrylic adhesive is used. Standard 76mm (3") plastic core.
9.5 W x 66m L (3/8" x 72 yd)

3M™ Multiple Tape Dispenser

Holds multiple tape rolls with a 76mm (3") inside diameter core; up to 15.2cm (6") total width. The special weight holds the dispenser steady during pulling/cutting. Maximum roll outside diameter 17.5cm (6-7/8").

Scotch^® Magic™ Tape 810
