Polypropylene Fiber-Reinforced Anti-Corrosion Adhesive Tape
PRODUCT PARAMETERS
Description
Product Description
Polypropylene reinforced fiber anti-corrosion tape is a high-performance pipe wrapping tape manufactured by coating a butyl rubber modified asphalt adhesive onto a unique net-like polypropylene fiber backing. This reinforced structure provides significantly higher tensile strength (≥60 MPa) and impact resistance compared to conventional tapes.
The tape is typically used with an anti-corrosion primer to enhance adhesion and sealing performance. It can be applied as a standalone anti-corrosion system for buried pipelines or as an outer protective wrap for visco-elastic systems, providing additional mechanical protection for exposed valves, flanges, and fittings.
Key Features & Applications
- Fiber-reinforced backing — delivers superior tensile strength and puncture resistance
- Cold application — no heating required, ready for backfilling immediately after wrapping
- Strong adhesion when used with primer
- UV resistant, aging resistant, and high compressive strength
- Ideal for oil & gas pipelines, water transmission lines, industrial piping systems, and as a protective outer wrap for visco-elastic tape
System Composition
The standard anti-corrosion system consists of anti-corrosion primer (applied directly to the steel pipe) + polypropylene reinforced fiber tape. For enhanced mechanical protection over visco-elastic systems, the tape can be wrapped directly over the visco-elastic tape layer.
Polypropylene fiber-reinforced adhesive tape performance index:
| The tensile strength | ≥18 |
| Nominal fracture strain(％) | ≥200 |
| 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
Installation Methods
The polypropylene reinforced fiber tape can be applied by manual wrapping or mechanical wrapping machine. Due to its high tensile strength, a mechanical wrapper is recommended for large-diameter pipelines to ensure consistent tension and avoid wrinkling.
Quick Installation Steps (as standalone system)
- 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.
Quick Installation Steps (as outer wrap for visco-elastic tape)
- Apply visco-elastic tape to the flange, valve, or irregular surface following standard procedures.
- Immediately wrap the polypropylene reinforced fiber tape over the visco-elastic tape with 50-55% overlap.
- Maintain uniform tension during wrapping to ensure tight contact and mechanical protection.
- Press the tape ends firmly to prevent lifting.
Key Reminders
- Backfilling can be done immediately after wrapping — no curing time required.
- For mechanized wrapping, avoid excessive tension which may stretch or damage the fiber backing.
- When used as an outer wrap, ensure the underlying visco-elastic tape is properly applied without gaps.
- Store in a dry, cool place between -10°C and 35°C, away from direct sunlight and heat sources.
