Product Overview

The Braided Self-closing Wrap-SW2202 is a polyester protective sleeve manufactured from monofilament and multifilament yarns. Its open-braid construction combined with a self-closing overlap mechanism delivers mechanical protection, effective heat dissipation, and tool-free maintenance access for wire harnesses across automotive, electronic, railway, telecommunications, and industrial pipeline applications.

When comparing the Braided Self-closing Wrap-SW2202 against alternatives such as metal wire loom or rigid conduit systems, its re-enterable design stands out for environments where harness access is required after installation. Unlike 1 2 heat shrink tubing, which requires heat application for permanent bundle sealing, the SW2202 can be opened, adjusted, and reclosed throughout the harness service life without tools or additional materials.

Verified Performance Characteristics

The Braided Self-closing Wrap-SW2202 is validated by three verified performance criteria addressing the most common failure points in harness protection projects.

Temperature Range: -40°C to +150°C. Verified by a 4-hour low-temperature test at -40°C and a 240-hour heat aging test at 175°C, both completed without brittle cracking or degradation. For designs in high-temperature environments such as engine bays, this documented test baseline removes uncertainty about thermal performance.

Abrasion Resistance: Over 10,000 Cycles (ISO 6722-1). Abrasion typically concentrates at bend points in complex routing geometries, not at entry and exit connectors. The Braided Self-closing Wrap-SW2202 is validated against this specific failure mode with ISO 6722-1 abrasion data, providing a measurable performance reference for specification work.

Flame Retardancy: FMVSS 302, Burn Rate Below 100 mm/min. In automotive interior and railway carriage installations, flammability compliance is a mandatory requirement. The Braided Self-closing Wrap-SW2202 meets FMVSS 302 requirements, eliminating the need for a separate flame-retardant layer in these regulated applications.

Application Scenarios

Automotive Harnesses and Engine Bay

Engine bay harness assemblies face simultaneous demands: sustained heat above 100°C, exposure to gasoline and engine fluids, mechanical vibration from the powertrain, and FMVSS 302 compliance for vehicle interior safety. The Braided Self-closing Wrap-SW2202 addresses all four requirements. Its gasoline and engine chemical resistance supports fuel-system adjacent routing. The open-braid structure dissipates heat from dense harness sections, reducing thermal aging of wire insulation under sustained load conditions.

Electronic Equipment and Industrial Wiring

In control cabinets, server enclosures, and telecommunications base stations, cable management routines require both thermal performance and periodic maintenance access. The Braided Self-closing Wrap-SW2202 provides heat-dissipating protection without sacrificing accessibility. The open-braid structure allows airflow through the cable bundle, preventing heat accumulation in high-density cable runs where elevated temperatures accelerate insulation degradation. The self-closing design allows cable additions and rerouting without destroying or replacing existing protection — a direct reduction in maintenance time over the equipment service life.

Railway and Pipeline Protection

Railway carriage cable runs and industrial hose bundles require protection withstanding vibration-induced contact wear over multi-year service intervals. The SW2202 braid construction maintains consistent mechanical protection at structural contact points where repeated vibration wears away less robust materials. Available in nominal inner diameters from 5 mm to 50 mm, the product covers a full range of standard hose and cable bundle sizes. Reel lengths vary from 25 m to 200 m depending on diameter, and the product can be field-cut to required lengths.

Key Features

• Working Temperature -40°C to +150°C: Validated by heat aging and low-temperature tests with no cracking or degradation. Reliable in both sustained high-temperature automotive environments and cold installation conditions.
• ISO 6722-1 Abrasion Over 10,000 Cycles: Consistent mechanical protection at bend locations where abrasion concentrates most in complex harness routing paths.
• FMVSS 302 Flame Retardant: Burn rate below 100 mm/min. Meets flame retardancy requirements for automotive and rail interior applications without additional protective layers.
• Open-Braid Heat Dissipation: Airflow through the braid prevents heat build-up in cable bundles, extending service life of both sleeving and cable insulation under thermal load.
• Self-Closing with 25% Edge Overlap: Minimum 25% edge overlap for secure closure. Opens without tools for cable modification or maintenance access at any point during service life.
• Chemical Resistance — Gasoline and Engine Fluids: Suitable for engine-bay routing where contact with hydrocarbon fluids is a normal operating condition.

Quality and Certifications

The Braided Self-closing Wrap-SW2202 is manufactured at a facility certified to ISO 9001, IATF 16949, ISO 14001, ISO 45001, and military standard GJB9001C. IATF 16949 certification supports supplier qualification from automotive OEMs and Tier 1 harness manufacturers, addressing batch consistency and audit readiness. Technical documentation including product specification sheets, material data reference sheets, and test report summaries is available to support procurement qualification and incoming inspection reviews.

Selection Notes

The Braided Self-closing Wrap-SW2202 is designed for applications requiring re-entry access, wide operating temperature range, chemical resistance, and flame retardancy in a single product. When comparing it against metal wire loom or conventional braid sleeving without self-closing capability, the primary differentiator is the overlap mechanism eliminating tools and fasteners for cable access.

For applications where 1 2 heat shrink tubing is specified at termination points for permanent sealing, the Braided Self-closing Wrap-SW2202 serves the bundle run between those terminations, where thermal management and future access are the governing design requirements.
