Why Sunbow Leads the PET Cable Sleeving Segment

Sunbow has spent over two decades building a focused, vertically integrated operation dedicated entirely to insulation sleeve R&D, production, and sales. Its PET cable sleeving lineup directly addresses the core pain points facing harness engineers today: protecting wires in high-flex, high-abrasion, and thermally demanding environments while meeting increasingly strict flame retardancy and halogen-free standards. With a monthly output exceeding 40 million meters across all sleeve categories and 2025 annual sales of USD 24.31 million, Sunbow operates at a scale that supports consistent global delivery.

Core PET Cable Sleeving Product Lines

Expandable PET Braided Sleeves (SB-PET-ES)
Designed for wiring harnesses that require frequent bending and expansion, the SB-PET-ES operates across a temperature range of -50 to 150°C. Its hallmark advantage is excellent elasticity and softness, allowing easy threading over pre-terminated harnesses. The sleeve provides expandable wrapping for physical protection and bundling of irregular wiring harnesses, making it especially suitable for scenarios requiring air circulation and heat dissipation. Full-color safety certifications are available to support color-coded harness identification systems.

Self-Wrap Braided Sleeves (SB-SC-B)
Manufactured from eco flame retardant PET monofilament and polyester braid, the SB-SC-B combines wear resistance, heat dissipation, and flame retardancy in a tightly wrapped format. Operating temperature: -50 to 150°C. The self-wrapping design simplifies installation in tight spaces, and full-color safety certifications support color coding across assembly lines.

Self-Woven Split Sleeves (SB-SC-W)
The SB-SC-W features a polyester woven open-split construction that provides flame retardancy, wear resistance, acid resistance, and dust protection. Its open structure allows easy wiring maintenance, replacement, and inspection without disassembling the harness — a significant productivity advantage for automotive and industrial automation applications. Temperature range: -50 to 150°C.

Velcro Braided Sleeves (SB-ES-V)
Built from polyester braid stitched with velcro closures, the SB-ES-V offers heat dissipation, elasticity, flame retardancy, and wear resistance in a format designed for cable organization and protection of power cords, computer wires, and heater cables. Temperature range: -50 to 150°C.

Heat Shrinkable Braided Sleeves (SB-PET-ES-HST)
Combining PET fiber with polyolefin monofilament braid, this sleeve shrinks to 50% of its original inner diameter upon heating, delivering a 2:1 shrink ratio. It serves as an effective noise reduction, flexibility, wear resistance, and thermal insulation solution for irregular-shaped pipes including automotive rubber tubes and plastic conduits. Temperature range: -50 to 150°C.
