Material Features

Orange PET Insulation Tape — ≥5kV Dielectric Strength

Biaxially oriented orange PET film provides dielectric strength ≥ 5kV — delivering reliable electrical insulation for EV high-voltage harnesses, motor windings, transformer components, and capacitor assemblies. The orange color provides mandatory IEC-standard high-voltage hazard identification simultaneously with electrical insulation function.

Orange Polyester Tape for EV High Voltage Harness — IEC Color Compliance

Thisorange polyester acrylic tape delivers the standardized orange color identification required by IEC 60445 and ISO 6469 for high-voltage cables in electric vehicles — ensuring service technician safety and regulatory compliance in EV, HEV, and PHEV powertrain wiring systems, battery pack assemblies, and charging system components.

Orange Polyester Masking Tape — 150°C Heat Resistance

Withstands continuous temperatures up to 150°C and short-term peaks up to 180°C — covering EV powertrain thermal environments, powder coating oven cycles, and electronics assembly processes without adhesive migration or orange PET film color fading or deformation.

Solvent-Based Acrylic Adhesive — Long-Term Stability

Thispolyester tape uses solvent-based acrylic adhesive — offering superior aging resistance, chemical resistance to automotive fluids, and moisture resistance versus rubber-based alternatives, with clean residue-free removal from high-voltage cable jackets, connector housings, and electronic components.

Clean & Stable Removal

Leaves zero adhesive residue after removal — critical for EV harness assembly where adhesive contamination on connector contacts or cable insulation affects high-voltage system reliability and service life.

Applications of Orange Polyester Acrylic Tape

• EV High Voltage Harness Insulation — IEC 60445 / ISO 6469 Compliant
  The primary application for orange polyester tape in modern manufacturing — used for wrapping, bundling, and insulating high-voltage cables in electric vehicle battery packs, motor drive systems, and charging infrastructure. Orange color complies with IEC 60445 and ISO 6469 mandatory color identification requirements for HV systems above 60V DC / 25V AC in EV powertrains.
• Orange PET Tape — Industrial Safety Warning Marking
  Used for floor marking, equipment hazard identification, and safety zone delineation in manufacturing facilities — orange is the international standard color for warning and caution identification in industrial safety systems (ANSI Z535 / ISO 3864), providing high-visibility hazard marking that withstands production floor temperatures and cleaning chemicals.
• Electrical Insulation — Motor & Transformer Components
  Provides reliable inter-layer insulation for transformer coils, motor windings, and capacitor assemblies in industrial electrical equipment — dielectric strength ≥ 5kV ensures safe electrical separation between winding layers. Orange color provides clear identification in quality control inspection of winding processes.
• Orange Polyester Masking Tape — Powder Coating & Surface Treatment
  Used for masking precision surfaces during powder coating, anodizing, and electroplating — orange provides high-visibility confirmation of masked areas during complex multi-zone masking operations on automotive components and industrial parts.
• Lithium Battery Pack Assembly & Cable Color Coding
  Used in EV battery module assembly for high-voltage cable identification, cell interconnect insulation, and battery management system (BMS) wiring color coding — orange color coding ensures compliance with EV safety standards throughout the battery pack assembly and servicing lifecycle.

Q1 | What is orange polyester acrylic tape used for?

Orange polyester acrylic tape is primarily used for EV high voltage wire harness insulation and color identification (per IEC 60445 / ISO 6469), industrial safety warning marking, and high-temperature electrical insulation in applications up to 150°C. The IEC-standard orange color provides mandatory high-voltage hazard identification while simultaneously delivering ≥5kV dielectric insulation performance.

Q2 | Why is orange the standard color for EV high voltage cables?

IEC 60445 and ISO 6469 standards internationally mandate orange as the identification color for high-voltage cables in electric vehicles, hybrid vehicles, and related charging infrastructure. This standardization ensures that service technicians worldwide can immediately identify high-voltage hazards — typically defined as systems above 60V DC or 25V AC. This orange PET insulation tape provides specification-compliant color coding for EV, HEV, and PHEV powertrain wiring.

Q3 | Can orange polyester tape withstand EV powertrain temperatures?

Yes. This orange polyester acrylic tape withstands continuous temperatures up to 150°C and short-term peaks up to 180°C — covering the thermal environments of EV motor compartments, battery pack assemblies, and power electronics enclosures without adhesive migration or orange color fading.

Q4 | Is orange PET tape suitable for industrial safety floor marking?

Yes. Orange is the international standard warning/caution color in industrial safety systems (ANSI Z535 / ISO 3864). This orange polyester masking tape provides high-visibility floor marking and equipment hazard identification that withstands manufacturing floor temperatures, cleaning chemicals, and physical abrasion.

Q5 | Do you support OEM customization?

Yes. We offer full OEM services including custom width, thickness, color, die-cutting, and private label packaging with low MOQ.

Q6 | Are free samples available?

Yes. We provide free samples; express shipping cost is covered by the buyer.

Q7 | What payment methods are accepted?

We accept T/T, PayPal, and L/C.

Q8 | What is the MOQ?

Q9 | How long does shipping take?

We ship via DHL, UPS, FedEx, or TNT. Delivery typically takes 5–8 business days worldwide.

Q10 | How is orange polyester tape different from standard orange PVC tape or wire harness tape?

Standard orange PVC tape (max 80°C) and orange cloth wire harness tape lack the thermal and dielectric performance required for EV high-voltage applications. This orange polyester acrylic tape uses a biaxially oriented PET film backing — providing 150°C heat resistance, ≥5kV dielectric strength, superior tensile strength ≥120 N/25mm, chemical resistance to automotive fluids, and clean residue-free removal. It meets IEC color standard requirements with the performance specifications demanded by EV powertrain engineering.
