Designed for high-performance electrical insulation, sealing, and protection in harsh environments. It shrinks uniformly when heated, forming a tight seal around wires, connectors, or components. Made from high-purity silicone rubber, it offers excellent thermal stability and flexibility. Ideal for aerospace, medical devices, automotive, and high-voltage electrical systems. Resistant to heat, chemicals, UV, and moisture, ensuring long-term reliability. Available in various shrink ratios, wall thicknesses, and custom colors to meet application needs
