High-Temp PPS Woven Wrap Around Sleeve

The STW-PPS Woven Wrap Around Sleeve is a high-performance protective solution engineered for extreme environments, featuring superior 200°C thermal stability and exceptional chemical resistance against oils, fuels, and solvents. Its innovative self-closing split design allows for rapid installation and effortless maintenance without disconnecting complex cable harnesses, providing a heavy-duty, inherently flame-retardant shield that is ideal for transit bus underbody wiring, engine compartments, and demanding industrial applications.


 

PPS Woven Wrap-Around Cable Sleeve is a premier, self-closing protective solution engineered for mission-critical wiring systems in harsh environments. Woven from high-tenacity Polyphenylene Sulfide (PPS) monofilaments, it delivers an unparalleled balance of extreme thermal stability (up to 200°C), chemical inertness, and mechanical toughness.

Its innovative split-side design with a persistent overlap allows for rapid retrofitting and effortless maintenance without the need to disconnect complex connectors or terminals.

 


 

Why Choose PPS Wrap-Around Sleeving for Your Application?

While standard Braided Cable Sleeving meets general needs, PPS Wrap-Around Sleeving is the definitive choice for high-exposure zones.
Unlike PET sleeves that soften at high temperatures, PPS remains structurally sound when exposed to engine heat, hydraulic fluids, and aggressive road salts. It is the industry standard for underbody harnesses in transit buses and heavy-duty EVs, where long-term reliability is non-negotiable.

 


 

Technical Features

  • High-Temperature Reliability
    Specifically designed for Class D/E environments, this wrap around sleeve withstands continuous operating temperatures up to 200°C. It is the ideal thermal barrier for heavy-duty vehicle exhaust and engine systems.
  • Chemical & Fluid Immunity
    PPS is globally recognized for its chemical inertness. This wrap around sleeve is impervious to hydraulic fluids, antifreeze, and aggressive solvents, making it a “fit-and-forget” solution for industrial machinery.
  • Innovative Self-Closing Design
    The “memory-effect” weave allows the wrap around sleeve to be wrapped onto existing cable harnesses without tools. This drastically reduces labor costs during retrofitting, maintenance, or repair.
  • Enhanced Abrasion Resistance
    The tight, woven structure acts as a sacrificial layer, protecting critical wiring from road debris, vibration-induced friction, and mechanical wear in harsh transit environments.
