PVC Electrical Insulation Tape Jumbo Roll
 | PVC Electrical Insulation Tape Jumbo Roll
|
Insulative Tape Company is a manufacturer of pvc electrical insulation tape jumbo roll for converters, electrical tape producers, wire harness suppliers, and electrical maintenance distributors. This jumbo roll features flexible PVC backing with a rubber pressure-sensitive adhesive, making it ideal for low-voltage wire insulation, cable joint wrapping, harness bundling, and subsequent slitting into finished electrical tape rolls. Sample tests indicate dielectric strength around 35-40 kV/mm, elongation between 160%-220%, stable adhesion under -18 C to 80 C, and minimal edge lifting or residue (0-1 mm) during short-term removal. Flame retardant options are available for applications requiring self-extinguishing performance.
Benefits
- Provides dependable low-voltage insulation where dielectric strength and flexible wrapping are both required (35-40 kV/mm tested)
- Soft PVC backing offers 160%-220% typical elongation, allowing smooth wrapping around curves and harnesses
- Rubber adhesive ensures strong overlap bonding and minimal edge lifting; residue and flagging typically 0-1 mm
- Flame retardant option is available for applications that require tested self-extinguishing behavior
- Jumbo roll format supports slitting into 19mm, 25mm, or other finished widths with consistent edge quality
- Short-term removal shows low residue, supporting cleaner installation
Applications
- Slitting into finished electrical tape rolls for low-voltage insulation
- Wire splice and cable joint wrapping (35-40 kV/mm dielectric reference)
- Harness bundling and protective wrapping for appliance, panel, and equipment assembly
- Electrical maintenance tape supply for contractors and service teams (tested peel adhesion and holding power)
- Coil wrapping, color coding, and secondary mechanical protection
What Should You Consider When Evaluating Dielectric Strength and Voltage Rating?
When selecting jumbo rolls for insulation tape conversion, dielectric strength and voltage rating should be considered together. Sample tests show typical dielectric strength of 35-40 kV/mm and peel adhesion of 5-8 N/25mm, with holding power around 2-4 h. Proper wrapping technique ensures effective insulation on splices and harnesses.

Product Overview
This pvc electrical insulation tape jumbo roll is engineered for converting into finished electrical tape rolls rather than packaging or retail use. The soft PVC backing conforms well around cable joints, wire splices, and harness bundles, while the rubber adhesive ensures consistent overlap bonding. For factory reference, total thickness is usually 0.13mm-0.16mm, with the PVC film itself around 0.08mm-0.11mm. In sample testing, dielectric strength typically reaches 35-40 kV/mm, peel adhesion measures 5-8 N/25mm, with holding power around 2-4 h. Voltage rating is expressed for low-voltage insulation (up to 600V-class reference).
Packaging & Loading
How Do Flame Retardant and Temperature Ratings Impact Safety in Electrical Insulation?
Flame retardant performance should be evaluated as a controlled formulation. Sample tests confirm that flame retardant tape maintains adhesion and elongation under 80 C, while clean slitting preserves edge quality. Observed residue and flagging are minimal (0-1 mm), ensuring reliable insulation on wire harnesses during maintenance or assembly.
FAQ
Is this jumbo roll used directly as finished electrical tape?
No. It is mainly supplied as jumbo roll material for slitting into finished electrical tape rolls, with minimal residue and flagging (0-1 mm) observed during sample checks.
Can it be used for high-voltage electrical insulation?
This tape is intended for low-voltage insulation reference (600V-class). Dielectric strength is typically 35-40 kV/mm. It is not designed for high-voltage insulation.
What should be tested before bulk production?
Check dielectric strength, flame retardant behavior, elongation, adhesive bonding, holding power, peel adhesion, slitting edge quality, residue, and flagging in sample tests.
Can the tape be made in different electrical colors?
Yes. Common colors include black, white, red, blue, yellow, green, and gray, suitable for insulation, identification, and wire harnessing applications.
