Material Features

Purple PET Insulation Tape — ≥5kV Dielectric Strength

Biaxially oriented purple PET film provides dielectric strength ≥ 5kV — delivering reliable electrical insulation for motor windings, transformer components, capacitor wrapping, and PCB assemblies in demanding electronics manufacturing and industrial applications.

Purple Anodizing Masking Tape — Chemical Resistance

Thispurple polyester acrylic tape resists sulfuric acid anodizing baths, chromic acid solutions, and electroplating chemicals — the acrylic adhesive seals tightly to aluminum and metal substrates, preventing bath solution penetration and ensuring precise anodization boundaries during Type I and Type II anodizing processes.

Purple Polyester Masking Tape — 150°C Heat Resistance

Withstands continuous temperatures up to 150°C and short-term peaks up to 180°C — covering anodizing oven cycles, powder coating processes, and automotive wire harness heat exposure without adhesive migration or purple PET film deformation.

Solvent-Based Acrylic Adhesive — Long-Term Stability

Thispolyester tape uses solvent-based acrylic adhesive — offering superior aging resistance, chemical resistance, and moisture resistance versus rubber-based alternatives, with clean residue-free removal from anodized aluminum surfaces, wire harnesses, and electronic components.

Clean & Stable Removal

Leaves zero adhesive residue after removal — critical for anodizing masking where surface contamination directly impacts coating quality and finish consistency.

Applications of Purple Polyester Acrylic Tape

• Purple Anodizing Masking Tape — Type I & II Anodization
  Protects non-anodized surface areas during sulfuric acid (Type II) and chromic acid (Type I) anodizing processes — the purple PET backing and acrylic adhesive seal against bath chemical penetration, ensuring clean, precise anodization boundaries on aluminum components and CNC machined parts.
• Wire Harness Color Coding — Automotive & Industrial
  Used for wrapping, bundling, and identifying wire harnesses in automotive manufacturing, industrial control panels, and aerospace wiring systems — purple serves as a standard identification color enabling instant visual differentiation in multi-color wiring assemblies.
• Electrical Insulation — Motor & Transformer Components
  Provides reliable inter-layer insulation for transformer coils, motor windings, and capacitor assemblies — dielectric strength ≥ 5kV ensures safe electrical separation between components in industrial electrical equipment.
• Purple Polyester Masking Tape — Powder Coating & Plating
  Used for masking precision surfaces during powder coating, electroplating, and Cerakote finishing — the purple color provides clear visual confirmation of covered areas, and clean adhesive removal protects finished surface quality.
• Cable Phase Identification & Medical Device Color Coding
  Purple is a recognized color code in medical device manufacturing and cable phase identification systems — this purple PET tape provides autoclavable-compatible (check specifications) color marking for instrument identification and cable management in controlled environments.

Q1 | What is purple polyester acrylic tape used for?

Purple polyester acrylic tape is primarily used for anodizing masking, wire harness color coding, and electrical insulation in industrial applications up to 150°C. The purple PET backing resists anodizing bath chemicals, and the distinctive purple color enables instant visual identification in multi-color wire harness and cable assemblies.

Q2 | Can purple polyester tape be used for anodizing masking?

Yes. This purple anodizing masking tape provides strong chemical resistance against sulfuric acid and chromic acid anodizing bath solutions — the solvent-based acrylic adhesive seals tightly to aluminum substrates, preventing bath penetration and ensuring precise anodization boundaries during Type I and Type II anodizing processes.

Q3 | What temperature can purple polyester tape withstand?

Thispurple PET insulation tape withstands continuous temperatures up to 150°C and short-term exposure up to 180°C — covering anodizing oven curing cycles, powder coating processes, and automotive wire harness heat exposure without adhesive migration or film deformation.

Q4 | Is purple PET tape suitable for wire harness color coding?

Yes. Purple is a standard identification color in automotive wire harness manufacturing and industrial cable systems. This purple polyester tape enables reliable visual differentiation between cable phases and wire bundles, reducing mis-assembly risk in complex multi-color wiring production.

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?

Low MOQ — 1 piece accepted for sample testing. Contact us for bulk order pricing.

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 purple polyester tape different from violet electrical tape or PVC tape?

Unlike standard PVC electrical tape (max 80°C) or vinyl color coding tape, this purple polyester acrylic tape uses a biaxially oriented PET film backing — providing 150°C heat resistance, ≥5kV dielectric strength, superior chemical resistance to anodizing bath solutions, and clean residue-free removal. It is engineered for demanding industrial environments rather than general-purpose electrical applications.
