PET Cloth Wire Harness Tape
OPALUS PACK manufactures PET Cloth Wire Harness Tape with woven polyester backing and acrylic or rubber pressure-sensitive adhesive for abrasion-focused automotive harness protection. The woven surface is intended for cable bundles that contact clips, brackets, body panels, connector branches, or warmer routing areas where a softer fleece construction may not provide enough mechanical protection.
This product should remain a PET-cloth page: thickness, peel adhesion, tensile strength, elongation, temperature grade, unwind, flagging, and cable-jacket compatibility are evaluated on the selected cloth construction rather than mixed with fleece or PVC harness-tape claims.

- Colors: Black, orange, gray, white, or project color
- Widths: 9 mm, 19 mm, 25 mm, 32 mm, 50 mm
- Use: Body harness, engine compartment harness, EV harness
Key Features
Product Overview
PET Cloth Wire Harness Tape is selected when the harness needs woven mechanical protection rather than only soft noise damping. The backing helps resist repeated rubbing at cable edges, clips, brackets, body panels, and branch points while remaining flexible enough for curved bundles and compact routing areas.
Rubber-PSA and acrylic-PSA grades should be separated by the approved harness duty. Rubber systems are generally evaluated for fast tack and manual wrapping behavior, while acrylic systems are used where higher-temperature ageing and longer-term bond stability are required. Do not transfer one grade’s abrasion, temperature, VOC, fogging, or flammability result to another adhesive construction. For wrapping sequence, overlap, branch points, and finishing checks, use How to Use Automotive Wiring Tape.
During sample review, customers check more than adhesion. Typical factory test ranges include 0.15 mm-0.30 mm thickness, 2.5-6.5 N/cm peel adhesion, 60-250 N/cm tensile strength, and 10%-40% elongation. Trial wrapping should also check edge curling, flagging after bending, unwind feel, odor, fogging reference, and compatibility with PVC, PE, PP, XLPE, or halogen-free cable jackets.
Benefits
- Polyester cloth backing: Resists abrasion from movement, clips, brackets, and cable-edge contact.
- Route-based adhesive: Rubber PSA supports quick tack; acrylic PSA supports heat and aging resistance.
- Flexible fitting: Sits closely around cable branches without making the harness bulky.
- Stable unwind: Helps workers keep consistent tension during manual or semi-automatic assembly.
- Interior approval support: Low odor, low VOC, and fogging reference can be checked.
- Specification control: Width tolerance, roll edge quality, adhesion, strength, and elongation can be confirmed.
How does PET cloth backing improve harness protection?
The woven PET structure adds a mechanically stable surface around cable bundles exposed to clips, brackets, body-panel edges, vibration, and repeated movement. Performance still depends on the exact yarn / backing construction, adhesive, thickness, test mandrel, and harness geometry. Use the LV312 or customer-specific abrasion / noise class only when it is documented for the selected grade; do not infer a class from the backing name alone.

Applications
- Body harnesses needing abrasion protection, flexible fitting, and steady unwind
- Dashboard wiring, door harnesses, seat wiring, and trunk cable routing
- Engine compartment harnesses using acrylic grades with -40 C to +125 C or +150 C options
- EV wire harness production requiring orange identification and cable jacket compatibility
- Harness assembly plants using manual or semi-automatic taping with controlled roll edge quality
Which adhesive system is better for your wire harness assembly?
The adhesive system should be selected by harness location, temperature requirement, and installation method. Rubber PSA is practical when fast initial tack, hand tearability, and flexible fitting are needed for interior body harnesses. Acrylic PSA is usually selected for higher heat resistance, stronger aging performance, cleaner holding, and better resistance to automotive operating conditions. For engine compartment or EV harness production, acrylic grades should be checked with abrasion class, peel adhesion, VOC or fogging reference, and cable jacket compatibility before sample approval.
FAQ
Is this tape the same as ordinary auto wire harness tape?
No. It focuses on PET cloth backing with a pressure-sensitive adhesive system for automotive harness protection.
Should I choose rubber PSA or acrylic PSA?
Rubber PSA is useful for hand tearability and fast tack. Acrylic PSA is selected for heat resistance and aging resistance.
Can it be used for EV wire harness production?
Yes. Suitable grades support orange identification, abrasion protection, stable unwind, and cable jacket compatibility.
What should be tested before batch use?
Check thickness, peel adhesion, tensile strength, elongation, temperature grade, abrasion reference, odor, fogging, unwind force, flagging, and cable jacket compatibility.
