2753 Silicone Coated Fiberglass Sleeving

2753 Silicone Fiberglass  Sleeve is Self-extinguishing sleeve which is designed for superior insulation and mechanical protection. Constructed from non-alkali fiberglass braid and coated with a resilient silicone resin, it offers high dielectric strength, with breakdown voltage options of 2.5kV, 4kV, and 7kV. It features excellent stiffness, cold resistance, and a self-extinguishing time of less than 10 seconds.

Chengrui Insulation supplies silicone coated fiberglass sleeves in various diameters 1 - 30mm, lengths, and thicknesses, supporting custom orders, bulk supply, and sample testing for global customers.

• Base Material: Fiberglass braided sleeving

• Coating: Self-extinguishing silicone resin varnish

Features and Advantages:

★High Temperature Resistance: Continuous operating temperature up to 180℃ (H-class), capable of withstanding even higher temperatures for short periods.

★Self-Extinguishing Flame Retardant: Meets flame retardant standards, with a self-extinguishing time of less than 10 seconds, forming insulating ash after combustion, and is non-conductive.

★Excellent Electrical Insulation: Provides high breakdown voltage (selectable 2.5kV, 4kV, and 7kV classes), with reliable insulation performance.

★Combining Mechanical Strength and Flexibility: Possesses good wear and tear resistance, maintaining a certain degree of rigidity and cold bending toughness, facilitating wiring and bundling in confined spaces.

It is specifically designed for the insulation and mechanical protection of wires, cables, and hoses under high-temperature and high-electrical-stress environments. It can operate stably within a temperature range of -70℃ to 200℃ (up to higher temperatures) and belongs to Class H insulation materials.
