Fiberglass sleeving coated with silicone resin is a flexible, high-temperature insulation sleeve woven from non-alkali fiberglass and impregnated with silicone resin under controlled thermal curing. It operates reliably between -60°C and 200°C and provides dielectric strength levels of 1.2 kV, 1.5 kV, 2.5 kV, 4 kV, and 7 kV depending on thickness and weave density. The coating ensures thermal stability and electrical isolation without brittleness or cracking under thermal cycling.
The base material is continuous filament non-alkali fiberglass, which offers superior tensile integrity compared to alkali-containing fibers. The silicone resin coating is applied to meet standard flammability self-extinguishing requirements per UL 1441 and provides resistance to abrasion, tearing, and chemical exposure. This sleeving is compatible with common Class H impregnation varnishes used in motor and transformer winding processes. Typical diameters range from 1.5 mm to 25 mm, with wall thicknesses of 0.2 mm to 0.8 mm, though exact dimensions vary by order.
This sleeving is commonly used in electric motors, transformers, generators, and high-temperature wiring harnesses where thermal and electrical protection is critical. Buyers include manufacturers of industrial motors, aerospace component suppliers, and transformer rewinders in North America, Europe, and Southeast Asia. Standard packaging is on cardboard cores or plastic spools, with lengths from 50 m to 500 m per roll. MOQ and lead time must be confirmed directly with the supplier as they vary by specification and order volume.

Before ordering, verify the exact dielectric strength rating and wall thickness of the sleeving sample against your application’s voltage and clearance requirements. Request test reports for flammability, tensile strength, and chemical compatibility with your varnish system. Confirm that the supplier can provide traceable batch documentation, even if certifications are not pre-issued. Do not rely on generic claims of UL, ROHS, or ISO without certificate numbers and issuing authority details.
Lead time typically ranges from 15 to 30 days for standard sizes, depending on order volume and production scheduling. Incoterms are usually FOB Shenzhen or CIF port of destination, but EXW is common for smaller orders. Payment terms are often 30% advance, 70% against copy of B/L. Confirm packaging method, spool type, and labeling requirements to avoid customs delays or handling damage. Always request a pre-shipment inspection report if ordering over 1000 meters.
Perform visual inspection for uniform coating, absence of bubbles or gaps, and consistent diameter. Use a micrometer to measure wall thickness at multiple points. Test dielectric strength with a high-pot tester per IEC 60243-1. Check for flexibility at low temperatures by bending a sample at -20°C. Request a Certificate of Conformity for each batch, including material composition, test results, and production date. Retain samples for future quality audits.
