A high-temperature silicone sleeve is a flexible, protective tubing made from a braided fiberglass base coated in a thick layer of silicone rubber. The combination of materials provides exceptional heat resistance, fire protection, and electrical insulation for critical hoses, cables, and wires in extreme environments. Key properties

• Thermal protection: While pure silicone rubber has a high-temperature rating, the addition of the fiberglass braid can significantly increase the continuous operating temperature and provide short-term protection from extreme heat and molten metal splash. Some products can withstand temperatures over 1,200°C (2,200°F) for short periods.
• Flame and splash resistance: The thick silicone rubber coating sheds molten metal splash and resists direct flame, preventing heat transfer and damage to the components inside.
• Excellent flexibility: Despite its durability, the braided construction allows the sleeve to remain highly flexible, making installation easier over irregular shapes, bends, and flanges.
• Good electrical insulation: The fiberglass base provides excellent dielectric strength, and the silicone coating ensures that the sleeve maintains its insulating properties even when wet.
• Fluid resistance: Silicone rubber is resistant to hydraulic fluids, lubricating oils, and fuels, protecting cables and hoses from corrosive chemicals.
• Abrasion resistance: The combination of fiberglass and silicone creates a tough, durable sleeve that resists abrasion and environmental damage. 

Common applicationsHigh-temperature silicone sleeving is essential in applications where heat, flame, or molten splash pose a risk to sensitive components. 

• Automotive: Protection for wiring, hoses, and fuel lines near hot engine parts and spark plugs.
• Industrial machinery: Used in manufacturing processes, furnaces, and smelters to protect electrical cables, hydraulic hoses, and pneumatic lines.
• Metalworking: Guards against molten metal splash and welding splatter in foundries and welding shops.
• Aerospace: Provides protection for wires and fluid lines in aircraft where high temperatures are a concern.
• Electrical appliances: Insulates wiring in household appliances like heaters and ovens.
• Marine: Shields fuel lines and wiring from heat and corrosion in demanding marine environments. 

Pure silicone vs. coated fiberglass

• Pure silicone: Sleeving made from pure silicone is typically softer and more flexible. It excels at maintaining its properties across a wide temperature range, but generally has a lower maximum continuous operating temperature than a silicone-coated fiberglass sleeve.
• Silicone-coated fiberglass: Combining the structural strength of a braided fiberglass interior with an exterior silicone rubber coating, this type of sleeve offers superior abrasion and high-heat resistance, making it better for extreme industrial and flame-resistant applications. 

Heat shrinkable sleeves are protective tubing designed to insulate, seal, and protect wires, cables, and joints when exposed to heat. Made from polyolefin or other thermoplastic materials, they shrink uniformly when heated, forming a tight fit around the application. These sleeves provide excellent electrical insulation, mechanical protection, and resistance to moisture, abrasion, chemicals, and environmental stress. Widely used in electrical, electronics, automotive, and industrial applications, heat shrink sleeves enhance safety and durability of connections. Available in various shrink ratios, colors, and sizes, they are easy to install using a heat gun and are suitable for both low- and high-voltage applications.
