KAPTON TAPE 12mm -300 DEGREE

KAPTON TAPE 12mm -300 DEGREE

KAPTON TAPE 12mm -300 DEGREE is a narrow high-temperature electrical insulation tape used for controlled masking, wire protection and insulation work in battery-pack assembly, electronics and heat-exposed production processes. Buyers commonly search for 12mm Kapton tape, 300 degree Kapton tape, polyimide electrical tape, high temperature insulation tape, battery pack insulation tape and lithium battery assembly tape, so the product is most useful when its size, electrical role and installation method are matched to the actual battery pack, enclosure or wiring job rather than selected by appearance alone.

For lithium battery, EV, inverter and energy-storage assembly, small accessories often influence serviceability and long-term reliability as much as the main electronic modules. Correct selection helps keep wiring organized, insulated and mechanically supported, while poor fit can create abrasion, loose joints, heat concentration or difficult maintenance. Use the exact product dimensions and electrical ratings as design inputs, and avoid treating a general accessory as a substitute for a correctly engineered protection component.

The 12mm width is useful where installers need accurate placement around cell edges, nickel tabs, BMS harnesses, terminal areas or compact electrical joints without covering a large surface. Kapton-type polyimide tape is widely searched as high temperature insulation tape, battery pack insulation tape and electronics masking tape because it combines a thin profile with dependable electrical isolation when the correct grade is selected. The 300-degree designation distinguishes this version from standard tape in the product range, but the final continuous-temperature limit should always be checked against the exact roll specification and adhesive system. Tape should not be used to compensate for damaged primary insulation or inadequate clearance between live conductors.

Choose by tape width, roll length, film thickness, adhesive type and the real operating-temperature requirement. For battery work, also check whether the tape must wrap cylindrical cells, protect prismatic cell edges, secure sense wires or insulate spot-welded nickel areas, because each use can require a different thickness and overlap.

Applications

• Lithium battery cell and module insulation.

• BMS balance-wire and harness protection.

• Nickel-tab and busbar masking during assembly.

• Electronics soldering and high-temperature masking.

• EV, inverter and ESS battery-pack workshop work.

Installation Guide

Clean and dry the target surface before applying the tape. Isolate battery circuits before placing insulation near live terminals or cell interconnects. Apply the tape without sharp folds, wrinkles or trapped metal debris, and maintain adequate overlap where the tape is being used as secondary electrical insulation. Do not stretch the tape so aggressively that it lifts from corners after installation. Keep sharp busbar edges and hot components from cutting or degrading the film, and inspect the taped area before the enclosure is closed.

Why Choose ARB Accessories?

ARB Accessories focuses on lithium-battery, EV, energy-storage and battery-pack assembly components. The catalog brings together BMS boards, connectors, insulation materials, battery wiring, terminals, fuses, enclosures, testing equipment and assembly tools. For battery builders, repair workshops and OEM buyers, sourcing related components from one specialist catalog can make specification matching and procurement easier. Final suitability should still be checked against the exact battery design, equipment model and electrical requirements before installation.
