Lightweight Battery Insulation Sleeve SMC Insulation Cylinder High Strength

SMC Insulation Cylinder

The SMC insulation cylinder is a core structural insulation component manufactured through a precision compression molding process using glass-fiber-reinforced sheet molding compound (SMC) as the primary raw material. Designed to be compatible with the company’s main SMC insulation material system, it integrates multiple functions—including structural support, high-voltage insulation, and safety protection—and is widely applicable to battery equipment in various scenarios, such as new energy and industrial energy storage.

I. Key Product Advantages

• Excellent Insulation Performance: Leveraging the inherently high dielectric properties of SMC material, these sleeves provide high-voltage insulation protection, effectively isolating battery cells from metal structures and eliminating the risk of electrical leakage. They eliminate the need for additional insulation components, thereby simplifying the module assembly process.

• Lightweight, High-Strength, and Durable: The glass-fiber composite structure balances lightweight design with high rigidity, reducing weight by 30%–40% compared to traditional metal end plates, while offering excellent tensile strength and impact resistance, making it suitable for long-term load-bearing applications.

• Strong Environmental Adaptability: Meets the UL94 V-0 flame retardant rating to suppress fire spread, while also offering corrosion resistance, moisture resistance, and salt spray resistance. It operates reliably across a wide temperature range of -50°C to 250°C and in complex, harsh operating conditions.

• High Customizability and Excellent Cost-Effectiveness: The compression molding process accommodates irregular shapes, embedded components, and multi-size customization to fit various battery module specifications, with controllable production costs at scale.

II. Main Application Scenarios

Suitable for new energy vehicle battery modules, residential and commercial energy storage systems, and grid energy storage equipment; also applicable for industrial backup battery enclosures in UPS power supplies, AGV forklifts, construction machinery, and marine equipment.
