High-Temperature Special Fiberglass Sleeving
Grade TGS-1W-600C · Continuous Duty to +600 °C

Technical datasheet · WCW (Shenzhen Wahchangwei Industrial Co., Ltd.)
DS-TGS-2026-01
Rev. 2026-10
Flame rating: UL VW-1
Construction: high-temperature fiberglass braid finished with a specialized heat-resistant treatment. Stays flexible and smooth at sustained temperatures where conventional coated sleeving turns brittle, and resists shedding and flaking in hot-air flow. Not intended as a primary electrical insulator — use as mechanical and thermal protection over pre-insulated leads. All sizes share one rating: −10 °C to +600 °C, 300–700 V, UL VW-1. Custom colors and constructions on request.

2 · Typical Applications

Hot-runner systems and manifold zones in plastics processing, smelting and casting equipment, automotive engine bays and exhaust-adjacent harnesses, ovens, air-fryer and heating appliances, continuously hot machinery — anywhere lead protection must survive sustained +600 °C service while the wire inside keeps its own insulation. The smooth braid also slides easily over bundles during assembly.
