Hotmelt Adhesive Heat Shrink Wrapid Tape for Joint Wrap Coating
Hotmelt Adhesive Heat Shrink Wrapid Tape is a high-performance corrosion protection solution designed for pipeline joints, field repairs, and girth weld coatings. Utilizing advanced radiation cross-linked polyolefin backing and a specially formulated hotmelt adhesive system, it provides a seamless, waterproof barrier against corrosive elements in oil & gas, water, and chemical pipelines.
✔ Superior Corrosion Protection
Forms a permanent, monolithic barrier with >99% water resistance (tested per ISO 21809)
Excellent resistance to cathodic disbondment (<5mm at 65°C per NACE TM0316)
✔ Engineered for Field Efficiency
Fast Installation: Shrinks uniformly at 120-150°C with propane torch (1-2 minutes per joint)
Self-Repairing Adhesive: Fills irregularities up to 3mm during heating process
UV Stability: 12-month outdoor exposure resistance without degradation
✔ Material Science Innovation
Backing: 3-layer co-extruded polyolefin (2.5mm nominal thickness)
Adhesive: Butyl rubber-based hotmelt with 85% solids content
Operating Range: -50°C to 110°C continuous service
| Parameter | Value | Standard |
|---|---|---|
| Peel Strength | ≥80 N/cm | ASTM D1000 |
| Dielectric Strength | ≥30 kV/mm | IEC 60243 |
| Impact Resistance | 10J at -30°C | ISO 21809-1 Annex G |
| Soil Stress Resistance | 1.5N/mm² after 30 days | DIN 30672 |
