Automotive adhesive tapes bond, mount, mask, and protect components throughout vehicle manufacturing. The main types are wire harness tape for wiring loom bundling, double-sided foam tape for trim and emblem mounting, masking tape for paint and coating lines, and surface protection tape for finished panels and glass.
Why Adhesive Tape Is Used in Automotive Manufacturing
Modern vehicle assembly lines use adhesive tape across dozens of applications because tape bonds deliver advantages mechanical fasteners cannot replicate. Tape reduces component weight by replacing screws and rivets. It distributes load across the full bond area, damps vibration and noise, and seals the joint against moisture and dust simultaneously.
Automotive adhesive tapes reduce vehicle weight, dampen noise and vibration, and bond dissimilar materials without drilling or mechanical fasteners.
Wire Harness Tape: Bundling and Protecting Wiring Looms
Wire harness tape is the most widely used tape in automotive manufacturing by volume. It wraps and bundles the wiring looms that carry power and data throughout the vehicle, protecting cables from abrasion, heat, and fluid exposure along their routing path.
- PVC harness tape: Chemical resistance and moisture protection for engine bay and underbody routing
- Cloth harness tape: Tears by hand, conforms around bends, abrasion-resistant for cabin wiring
- Fleece harness tape: Highest NVH damping for cabin interiors where noise reduction is a priority
Wire harness tape bundles and protects automotive wiring looms against abrasion, heat, and fluid exposure along the routing path.
Fleece wire harness tape provides noise and vibration damping for wiring looms in automotive cabin interiors.

Double-Sided Foam Tape: Trim and Emblem Mounting
Double-sided acrylic foam tape mounts trim strips, body moldings, emblems, and nameplates without drilling. The foam core compresses to fill surface irregularities and absorbs vibration. Acrylic adhesive resists UV degradation, plasticizer migration from plastic substrates, and temperature cycling on vehicle exteriors.
Double-sided acrylic foam tape mounts automotive emblems and trim strips without drilling, dampening vibration and sealing the joint simultaneously.
Acrylic foam tape distributes stress across the bond line and resists UV and temperature cycling in automotive exterior applications.
Masking Tape in Automotive Paint and Coating
Automotive paint shops use masking tape to create clean, sharp paint lines through spray painting and oven bake cycles. The tape must hold the paint edge cleanly through the curing process and remove without tearing or leaving adhesive residue on the painted surface.
High-temperature automotive masking tape holds clean paint edges through spray and bake cycles without bleed-through or residue.
Surface Protection Tape in Assembly and Transit
Finished painted panels, glass, and polished trim are vulnerable to scratching during body assembly and vehicle transport. Surface protection tape is applied at the paint shop and removed on delivery. It must release cleanly without adhesive transfer even after outdoor transit exposure.
Surface protection tape shields painted panels and glass from scratches during vehicle assembly, transport, and dealer handling.
Other Automotive Tape Applications

Frequently Asked Questions
What tapes are used in automotive manufacturing?
Wire harness tape, double-sided foam tape, high-temperature masking tape, and surface protection tape are the main automotive tapes, used for wiring, trim mounting, paint masking, and panel protection respectively.
Why use tape instead of screws in automotive assembly?
Tape reduces vehicle weight, damps noise and vibration, distributes stress evenly, seals the joint, and bonds dissimilar materials without drilling.
Does foam tape work on automotive plastics?
Double-sided acrylic foam tape bonds to automotive plastics when the surface is clean and properly prepared. Low surface energy plastics often need a primer for full bond strength.
What tape bundles car wiring looms?
Wire harness tape in PVC, cloth, or fleece grades, each suited to different routing environments and NVH requirements.
