Polyethylene Anti-Corrosion Adhesive Tape
Product Highlights
Product Description
Polyethylene anti-corrosion tape is a high-performance pipe wrapping tape manufactured by thermally laminating a butyl rubber-based adhesive onto a polyethylene backing film. It is available in three protection levels — Ordinary, Reinforced, and Extra Reinforced — allowing customers to select the appropriate grade for inner tape (corrosion insulation) and outer tape (mechanical protection) based on specific project requirements.
Recommended Applications
- Steel pipeline corrosion protection in oil and gas industries
- Water transmission pipeline anti-corrosion
- Chemical plant piping systems
- Power industry pipeline protection
- Field joint coating and external pipe wrapping
System Composition
The complete anti-corrosion system consists of polyethylene anti-corrosion tape (inner layer) + polyethylene protective tape (outer layer) + anti-corrosion primer. The primer fills surface irregularities and enhances bonding strength between the tape and steel pipe.

| Peeling strength（N/cm） | ≥25 |
| Base film dielectric strength(MV/m) | ≥30 |
| Volume resistivity(Ω·m) | ≥1×10¹² |
| Heat-proof aging(％) | ≥75 |
| Moisture absorption(％) | ≤0.20 |
| Water-vapor permeability(mg/[24h·cm²]) | ≤0.25 |
Installation Guide & Precautions
Two Installation Methods
The polyethylene anti-corrosion tape can be applied by manual wrapping or mechanical wrapping machine, depending on project scale and site conditions.
Quick Installation Steps
- Surface preparation: Remove rust to Sa2.5 (blasting) or St3 (manual).
- Primer application: Apply anti-corrosion primer evenly on the prepared steel surface.
- Tape wrapping: Wind the tape spirally with 50-55% overlap, maintaining uniform tension.
- Inspection: Check for smooth overlap edges, no bubbles, wrinkles, or lifted ends.
Key Reminders
- Backfilling can be done immediately after wrapping — no curing time required
- For mechanized wrapping, adjust the tensioner to apply proper tension
- Store in a dry, cool place between -10°C and 35°C, avoid direct sunlight
