China best selling silicone fiberglass sleeve 2.5kv/4kv high tear strength slight expandability for easy installation

Product Description:

The Silicone Fiberglass Sleeve is a high-performance protective component engineered to deliver reliable insulation and structural durability for critical industrial components in harsh operating environments. Crafted from premium composite materials, it exhibits excellent resistance to high temperatures, chemical corrosion, and mechanical stress, rendering it a versatile protective solution for a broad spectrum of industrial applications including wiring, hydraulic hoses, and cable assemblies. 1. Mechanical Performance The product features a tensile strength of 4.5MPa, a core mechanical attribute that enables it to withstand sustained mechanical loads, abrasion, impact, and tensile forces without tearing or permanent deformation. This structural robustness ensures the integrity of wrapped components even in high-vibration or high-stress working scenarios, providing long-term stable protection for internal parts. 2. Installation Adaptability With inherent high flexibility, the sleeve can be seamlessly conformed to components of various shapes and dimensions, streamlining the installation process and improving construction efficiency. Its flexibility also allows it to adapt to the dynamic movement and vibration of equipment (such as in automotive, aerospace, and manufacturing equipment) without compromising its protective performance, making it suitable for both static and dynamic application scenarios. 3. Dimensional and Appearance Attributes • Color: The product adopts a uniform bright white finish, which not only ensures a neat and standardized appearance of the equipment but also facilitates rapid identification and visual inspection of insulated components during daily maintenance and safety checks. • Width Specification: The 50mm width is optimized for universal applicability, balancing full coverage of most cables, wires, and hoses with convenient operation. It can meet the protection needs of most conventional projects without additional customized processing, reducing procurement and application costs.  4. Corrosion Resistance The composite structure of fiberglass base material and silicone coating forms a dense protective barrier, which can effectively isolate internal components from moisture, corrosive chemicals, and salt spray. This performance makes it applicable to harsh industrial scenarios such as marine engineering, chemical processing plants, and outdoor open-air installations, where it can resist the erosion of corrosive media and extend the service life of wrapped components. 5. Thermal and Flame Retardant Protection As a specialized fire-resistant fiberglass sleeve, it integrates the inherent high-temperature resistance of the fiberglass core and the enhanced thermal stability of the silicone outer layer. It can maintain structural integrity and protective performance under conditions of direct flame exposure or long-term high-temperature operation, effectively preventing heat damage to electrical wiring, hydraulic pipelines, and other precision components, and is suitable for high-temperature working environments such as engine compartments and industrial furnaces. 6. Electrical Insulation Performance In addition to thermal protection, the sleeve has excellent dielectric properties, which can effectively isolate electrical interference and electromagnetic noise, reduce the risk of short circuits and electrical faults, and enhance the operational safety and stability of the protected system. It is widely applicable to electrical safety-critical fields such as power generation systems, automotive electronic components, and industrial control cabinets. Product Overview The Silicone Fiberglass Sleeve is a multi-functional protective component with comprehensive performance advantages including high tensile strength, flexible adaptability, strong corrosion resistance, and excellent thermal and electrical insulation. It can meet the diverse application needs of fiberglass fire sleeves, silicone insulation sleeves, and high-temperature resistant fiberglass sleeves, and provides reliable safety protection and service longevity for industrial components in extreme working conditions, fully meeting and exceeding the professional requirements for industrial protective materials.
