Acetate Adhesive Cloth Tape

Acetate Adhesive Cloth Tape  Backing: acetate cloth Adhesive: acrylic or rubber Color: black or white Thickness: 0.20mm-0.25mm typical Roll length: 30m, 50m or custom Use: insulation, harnesses, coils Contact Us

PVC Electrical Tape Company is an acetate adhesive cloth tape manufacturer producing flexible insulation tape for electrical insulation, harness binding and coil wrapping. Made with acetate cloth backing and acrylic or rubber pressure-sensitive adhesive, this tape tears easily by hand and fits well around uneven surfaces, wire exits and coil edges. It is supplied in clean slit rolls for transformers, power supplies, motors and electronic assemblies where stable wrapping, varnish compatibility and practical insulation support matter.

Benefits 

• Acetate cloth backing conforms well around curved coils, wire groups and irregular insulation surfaces.
• Easy hand tearing helps operators finish wraps without using blades near wires, windings or soldered leads.
• Rubber adhesive grades give stronger initial tack for harness bundling and coil edge holding.
• Acrylic adhesive grades support cleaner handling, lower odor and better aging stability.
• The cloth structure can absorb varnish or resin during coil finishing and insulation treatment.
• Clean slit edges help reduce fuzz, uneven overlap and loose fibers on narrow-width rolls.
• Reference peel adhesion of 5-10 N/25mm helps compare tack levels between adhesive grades.
• Tensile strength around 120-156 N/25mm supports manual wrapping tension without making the tape too rigid.
• A 24-hour edge lift check on cable jackets or varnished coils is recommended before mass use.

Applications 

1. Wire harness bundling inside appliances, control units and electronic equipment.
2. Flexible wrapping on internal cable groups, branch points and lead exits.
3. Outer wrapping on transformer coils, relay coils and small motor windings.
4. Transformer coil areas that need varnish absorption and conformable wrapping.
5. Local insulation around bobbin edges, soldered joints, crossover points and component corners.
6. Power supply assembly fixing where wires, coils and insulation layers need neat positioning.
7. Temporary holding of insulation layers before varnish, resin treatment or final assembly.
8. Narrow-width wrapping where clean slit rolls reduce edge fray and uneven overlap.
9. Electrical harness binding tape use where cable jacket compatibility must be checked first.

How does acetate cloth backing help during coil wrapping?

Acetate cloth backing gives the tape a soft but stable structure, so it can follow coil edges, winding turns and small-radius bends without lifting too quickly. During transformer, motor and power supply assembly, cloth tape for coil wrapping should lie flat over uneven insulation layers and component leads. The typical 10%-20% elongation range gives slight working tolerance during manual application, but it should not be treated as a high-stretch film tape. When the coil is dipped, brushed or finished with insulating varnish, the cloth surface can take in part of the coating instead of acting like a slick barrier. After curing, adhesion should be checked at lead exits, outer wraps and inter-layer fixing points.

Technical Data Sheet

Product Overview

Our acetate cloth electrical insulation tape is made for electrical assembly work where the tape needs to feel soft in the hand but still stay controlled during wrapping. The acetate fabric backing bends around bobbin edges, soldered lead exits, harness branches and small component corners without the stiffness often found in film-backed tapes. With a typical total thickness of 0.20mm-0.25mm, it gives enough body for insulation wrapping while still allowing operators to tear and press it into place by hand.

Different surfaces need different adhesive behavior. Rubber adhesive is often chosen when stronger initial tack is needed on wire bundles, coil edges or rough insulation layers. Acrylic adhesive is better suited when cleaner handling, lower odor and stable aging are more important. Before repeated production, we recommend testing the tape on the actual cable jacket, varnished coil surface or insulation layer to check adhesion, edge lift and possible adhesive transfer.

In coil work, this acetate fabric insulating tape offers a useful advantage: the cloth surface can absorb part of the insulating varnish or resin during finishing. That makes it suitable for outer coil wraps, lead holding points and inter-layer fixing areas before varnish curing. Roll quality also matters in daily use. Clean slitting, stable unwind and typical +/-0.5mm slit width tolerance on narrow rolls help reduce edge fray, loose fibers and uneven overlap near tight component areas.

Where is acetate adhesive cloth tape normally used in electrical assemblies?

Acetate adhesive cloth tape is used where flexible insulation, neat hand wrapping and surface conformity are more important than heavy mechanical reinforcement. In harness work, it can hold appliance wires, electronic leads and internal cable groups while keeping the wrap controlled around bends and branch points. In coil production, it is used for outer wrapping, tabbing, component holding and local insulation around transformer coils, relay coils, solenoids and small motor windings. For narrow spaces, clean slit rolls help operators work close to bobbins, soldered lead exits and irregular surfaces without excessive edge fray. If the assembly involves heat exposure or varnish curing, sample rolls should be checked for edge lift, adhesive transfer and surface staining on the actual part.

FAQ

Is this tape the same as ordinary cloth tape?

No. This product uses acetate cloth backing for electrical insulation, harness binding and coil wrapping. It is not designed as packaging tape, bookbinding tape or ordinary clear acetate film tape.

Can the tape be torn by hand?

Yes. The acetate cloth backing allows easy hand tearing during manual wrapping. This helps operators finish a wire bundle, coil edge or lead exit area without using a knife near electrical parts.

Which adhesive should be selected?

Rubber adhesive is suitable when stronger initial tack is needed. Acrylic adhesive is better when the application needs cleaner handling, stable aging and lower odor. Final selection should be tested on the actual cable jacket, insulation surface or varnished coil.

Can this tape be used at 260 C?

No general 260 C claim should be made for standard acetate cloth tape. Typical working grades are normally selected within lower electrical insulation temperature ranges, such as 85 C-130 C depending on adhesive system and tested grade.
